welcome to energy evolution iithe changing face of canadian energy supply
The natural gas industry has undergone dramatic changes over the past few years both globally
and within Canada. Unconventional gas has emerged as an abundant low-cost energy source
that has the potential to form the foundation upon which North American energy strategies and
security can be built. It is estimated that there is greater than 100+ years of potential supply at
current consumption levels in North America. Although a market oversupply of natural gas con-
tinues to impact prices, interest in unconventional resource development remains significant,
specifically where shale gas is involved. Industry continues to show amazing resilience and an
unrelenting commitment to evolve and remain competitive.
Natural gas is the cleanest-burning fossil fuel with only half the greenhouse gas (GHG)
emissions of coal and 25 per cent less GHG emissions than diesel fuel. Increased utilization
of natural gas will not only play a key role in meeting Canadian emissions reduction targets,
but also ensures that our country has sufficient energy supplies to meet our growing de-
mands while other forms of renewable energy technology are developed.
The key to unlocking the unconventional natural gas resources of Canada and North
America has been the application of new and emerging technologies. Horizontal drilling,
multi-stage hydraulic fracturing and reservoir monitoring technologies are some examples
of the technologies that have led to the dramatic growth of natural gas supply and economic
production. Unconventional resources development now encompasses numerous geo-
graphic regions of the continent and, in many cases, regions that are relatively new to the
oil and gas industry. Development of our country’s oil and gas resources continues to drive
the economic engine in Canada and provides economic growth and opportunity to many
regions from coast to coast.
While at times we as Canadians take our energy supply for granted, it is worthwhile to
reflect on the positive impact that unconventional resource development is having on our
economy. This guidebook and directory furthers the understanding of the technology be-
hind the exploration for and development of unconventional resources, the opportunities for
reduction of Canada’s GHG emissions and the important benefits to our energy supply and
economy. A comprehensive list of businesses, associations and individuals with interest in
unconventional resources is also included.
The Canadian Society for Unconventional Gas will continue to play an important role in
the transfer of technical unconventional gas knowledge from industry to the public. The so-
ciety has a wealth of information about the unconventional resource industry and we en-
courage you to visit www.csug.ca for more information.

greetings from the ministry of energy, government of alberta
I am pleased to have this opportunity to welcome you to Energy Evolution II-The Changing
Face of Canadian Energy Supply. This is an exciting and rewarding time in the unconven-
tional resource development industry in Canada. The vast potential of unconventional gas in
Canada and in the United States has created a fundamental shift in North America’s natural
gas industry. Over the last several years, the North American natural gas market has shifted
from one of scarcity to one of abundance.
Unconventional gas production in North America has increased significantly as industry
has overcome the challenge of unlocking enormous unconventional gas resources using
technologies like horizontal drilling and hydraulic fracturing. This has had a significant im-
pact on Alberta and is presenting industry with new opportunities and challenges. These
challenges offer the chance to learn and to adapt new techniques and technologies.
This guidebook and directory will help add new perspectives and I know you will find it a
useful resource.
The Honourable Ron Liepert
Minister of Energy
“The vast potential of unconventional
gas in Canada and in the United States
has created a fundamental shift in North
America’s natural gas industry.”

greetings from the ministry of energy and mines, government of british columbia
Just a few short years ago, British Columbia was on the verge of reaching peak production
from natural gas. Now, production of our largest energy commodity could double by the end
of the decade.
Unconventional gas changed everything, creating an abundant supply of natural gas
available to respond to growing market demands.
Despite the uncertainty created by low commodity prices, British Columbia’s competi-
tive advantages retain long-term confidence in the province’s natural gas sector. Our royalty
programs stimulate growth and maintain production. Industry activity provides jobs, sup-
ports families and strengthens our rural communities.
Liquefied natural gas (LNG) projects are gaining momentum, with global LNG trade ex-
pected to increase by 50 per cent by 2020. With abundant reserves and a close proximity to
new markets, British Columbia is in a unique position to take advantage. We recently joined
Alberta and Saskatchewan to forge a commitment to target overseas areas looking to re-
place carbon-intensive technologies. Industry-led projects now in development would give
British Columbia the ability to supply our natural gas—the world’s cleanest-burning fossil
fuel—to these new markets.
At the same time, modernized regulations brought in last year encourage the use of in-
novation and increase our commitment to responsible development. The province and the
BC Oil and Gas Commission will continue to work with First Nations, communities and in-
dustry to maintain North American–leading standards for unconventional gas practices.
It is crucial that we continue to work together to keep British Columbia’s natural gas sector re-
sponsible and competitive. The sector remains an economic engine for our province, and giving
it the opportunity to grow and diversify will only strengthen the prospects of the future.
The Honourable Rich Coleman
Minister of Energy and Mines and Minister Responsible for Housing
“It is crucial that we continue to work
together to keep British Columbia’s natural
gas sector responsible and competitive.”

greetings from the ministry of energy and resources, government of saskatchewan
In recent years, Saskatchewan has quietly and confidently become a force in Canadian
energy supply. Our province accounts for over one-quarter of Canada’s primary energy pro-
duction and our per capita energy production is the highest in Canada.
Our primary energy production comes from coal, oil, natural gas, hydro, uranium, wind
and biofuels. We are the only province in Canada that has commercial production from all
these sources.
Saskatchewan is Canada’s second-largest oil producer and its third-largest producer of
natural gas. Oil and gas is now our largest industry, and thus while we are still known as
wheat country, we now proudly wear the mantle of oil country as well.
Our province has more than 40 billion barrels of conventional oil in place and nearly 13 trillion
cubic feet of natural gas in place. While much of this resource wealth is beyond reach for now,
new technology continues to unlock our oil and gas plays through leading-edge enhanced oil
recovery techniques and through world-renowned CO2 capture and storage methods.
Even though natural gas has been produced in the province since the 1930s, new chap-
ters in our gas story are still being written. We have untapped shale gas potential on the
west and east sides of the province and are still evaluating the extent of our natural gas in
coal resources, which are primarily in the southeast and southwest parts of the province.
The oil and gas industry operates in a very favourable business climate in Saskatchewan,
with a supportive government and fiscal and regulatory regimes that are appreciated by
industry for their certainty and stability. Our government continues to support technological
innovation, and last year provided an incentive to encourage horizontal drilling of gas wells.
The possibilities are endless in Saskatchewan for companies developing conventional
and unconventional resources. We encourage you to explore the energy opportunities in our
province and discover for yourself the Saskatchewan advantage.
The Honourable Bill Boyd
Minister of Energy and Resources
“The possibilities are endless in Saskatchewan
for companies developing conventional and
unconventional resources. ”

greetings from the department of natural resources, government of new brunswick
New Brunswick has a rich history in the development of oil and natural gas. One of the first
oil wells in North America was drilled in New Brunswick in 1859, as four wells were drilled
near what is now the city of Moncton.
The search for oil and natural gas in this province has been ongoing ever since.
The Government of New Brunswick has identified shale gas exploration and development
as well as related industrial activity as potentially having significant economic benefits for
our province. The government was elected on a commitment to “support the responsible
expansion of the natural gas sector while ensuring the safety and security of homeowners
and our groundwater supply.’’
Since the year 2000, more than 65 oil and natural gas wells have been drilled in the prov-
ince. About half of these are currently producing natural gas and four are producing oil.
There are another 12 producing oil wells that were drilled prior to 2000.
As of April 2011, there are 71 oil and natural gas agreements in place with nine companies
that cover approximately 1.4 million hectares.
The commissioning of the Maritimes and Northeast Pipeline that runs through southern
New Brunswick in 1999 and the discovery of natural gas in Sussex in 2000 sparked an ex-
ploration boom. Since then, more than $374 million has been invested in the exploration and
development of oil and natural gas in New Brunswick.
The oil and gas industry in New Brunswick plans at least an additional $200 million in ac-
tivity to be completed within the next two years.
The continued growth of New Brunswick’s oil and natural gas industry is important to
contributing to the province’s economy.
The Honourable Bruce Northrup
Minister of Natural Resources
“Support the responsible expansion of the natural
gas sector while ensuring the safety and security of
homeowners and our groundwater supply. ”

Natural gas was until recently touted as the perfect bridge to a future world of renewable resources. With today’s low prices and long-term supply, it’s looking more like the future itself.
By Graham Chandler
“Clean, renewable and transitional energy resources in Alberta are
more than capable of meeting future demand in the province, even
if electricity consumption doubles over the next 20 years,” reads
Greening the Grid. The paper’s most ambitious scenario says wind
power, natural gas cogeneration and improved efficiencies could lead
the way in reducing coal’s contribution—currently 74 per cent—to just
seven per cent.
Could it happen that fast?
“That would be on a war footing,” says Simon Mauger, director of
gas services for Ziff Energy Group. “But you could do it in that kind of
time frame. I think at least 30 per cent would have to be natural gas.”
Importantly, the study demonstrates the prospects for natural gas
going forward.
The role of natural gas in North America’s energy future has
been revolutionized in recent years. From its perception as a fuel
to bridge us into a sustainable future powered by renewable re-
sources, it is instead now presenting itself as the foundation fuel
of the future.
“The language of gas as a bridge was popular a couple of years
ago when we hadn’t seen this shale gas revolution,” says Tim Egan,
president and chief executive officer of the Canadian Gas Association.
“We had higher gas prices and they were much more volatile.”
Moreover, the assumption was that natural gas was a more lim-
ited resource than it’s proving to be; certain technologies weren’t
as affordable with gas. “Gas is part of the energy future that can
partner with a number of things,” says Egan.
A major driver is of course the looming requirement for all new coal-fired
generating plants to meet stringent greenhouse gas emission targets.
In June last year, Jim Prentice, then federal minister of the en-
vironment, announced plans to impose new regulations on coal-
fired electricity-generation plants that would eventually force them
to match natural gas combined-cycle plant emissions—or shut
down. Many of Alberta’s active coal plants are nearing retirement:
three-quarters of them were built in the 1970s and 1980s. Much the
same goes for coal-fired generation in the United States.
“Even before the announcement, gas was capturing a large part of
the new electrical-generation market in North America,” says Mauger.
“The main reason is they are cheaper to build. And you can build them
with all the regulatory approvals sometimes in as little as two years.”
Currently the only way any new coal plants will be able to comply
with the proposed rules is through carbon capture and storage—never
before done on a commercial scale—and the cost of adding that infra-
structure will be no match for the price of natural gas plants.
“Long term, for coal, it’s not a great development,” says Egan.
“It requires an even greater focus on the development of new tech-
nology. For gas, it is a good-news story in the long term. We think
the more opportunities to use gas, the more appreciation people will
have for the fuel.”

He adds that, generally speaking, it’s becoming more and more
difficult to build big plants and transmission lines, too.
“There is a social reaction against very large infrastructure,” he
says. “Because we are increasingly an urban society, people are
moving more and more into larger centres and don’t want big indus-
trial facilities nearby.”
Egan sees that trend boosting opportunities for gas. “In a
more distributed generation [network], more use of gas as a
foundation fuel in integrated domestic systems [can occur],”
he says, citing deployment of new technologies in transporta-
tion, for example, and biomethane, which is a renewable nat-
ural gas from biomass sources.
Domestic systems can include “micro-CHP [combined heat and
power],” says Egan. “These are very small units where you can use
a gas unit in your home that would generate both heat and electri-
city—they offer incredible efficiencies and environmental benefits,
and the affordable delivery of energy services to people.” He says
today they are more for small industrial installations and buildings
but will ultimately be available for individual homes.
A more regionalized, natural gas–powered promise for the future
would then shape up as the major source complementing clean
renewables. Other technologies, especially renewables like wind
and solar, are expensive alternatives that generally need heavy
subsidization.
“The cost of wind and solar is significantly higher than other sources
that are available today,” says Mauger. “And where we have the wind
isn’t necessarily where the people are. We can look at and talk about
renewables, however, there are fundamental principles: the sun doesn’t
always shine; the wind doesn’t always blow. Consequently, whenever
we look at renewable rapid growth, which we include in our forecast,
[we have] that as a very small component.”
And in the current climate of high government debt and growing
public resentment to wind power turbines, chances those will be
powering the future are slimming more with time. Witness the recent
Ontario government decision to hold off indefinitely from an ambi-
tious Great Lakes wind power program and the United Kingdom’s
proposal to cut government financial support for large solar-
generation plants.
“How practical are they?” asks Mauger. “They’re practical if
you’ve got subsidies.”
These and other barriers to the penetration of renewable tech-
nologies bode well for natural gas.
“In the short to medium term, it’s really the fuel of choice,” says
Mauger. “We have found a negative correlation between natural gas
prices and electrical generation using gas. The reason behind that is
natural gas can be used for peak shaving or peak generation; you can
spool the plants up very quickly and turn them off very fast. You can do
the same to a lesser extent with coal, but you have a lot of waste heat.” ›
ENERGY EVOLUTION II // 17
SUSTAINABILITY
It’s not just electricity generation that makes natural gas the fuel for the
future; liquefied natural gas (LNG) can be used in trucks and buses.
“The Port of Los Angeles uses it in their on-site fleet,” says
Mauger. “I might be a little dubious on the safety factor, but proof-
of-concept projects are working out there today.”
On the positive side, however, the attraction of LNG is it’s much
greater range than compressed natural gas—more potential energy
can be packed into a similarly sized fuel tank.
Then there’s the refuelling infrastructure needed for the LNG op-
tion, which the Canadian Gas Association’s Egan says has been
studied thoroughly by the association.
“We have been focusing on key heavy transport corridors, for
example, from Fort McMurray to Edmonton and Vancouver,” he
says. “Where there are significant volumes of trucking you can look
at strategic placement of refuelling [stations], so that it is viable for
trucking companies.”
He notes that it’s already happening: a Quebec-based truck fleet
has been partnering with Gaz Métro to develop refuelling stations
along busy intercity corridors. As these smaller projects prove up
the concept it can expand.
Or, trucks’ tanks might be filled with another natural gas product that
wouldn’t even require vehicle conversions: diesel. Right now it’s expen-
sive, but as crude prices climb, it approaches competitiveness.
“We’ve reached the peak of light sweet crude,” says Mauger. “In
general, a barrel is becoming heavier, sourer and needing modifica-
tions to refineries.” Ziff’s recent economic analyses of available gas-
to-liquids technologies suggest capital costs “of maybe $50 or $60
a barrel and feedstock costs of $4 per mcf [thousand cubic feet].
Each barrel takes 10 mcf to produce, so that’s $40 a barrel for feed-
stock. So, [that’s a] total cost of $90 to $100 a barrel. And what’s oil
today? A hundred and change.” So, he reckons, we are within “spit-
ting distance of the economics.”
It’s apparently behind the South African firm Sasol’s decision to
take a 50 per cent stake in Talisman Energy Inc.’s shale gas assets
in British Columbia’s Montney basin.
“If they can get the capital cost down, that’s the key issue in terms
of economics,” says Mauger.
But with all these transport and electrical power generation con-
versions to gas, how will it affect the 100-year supply trumpeted by
the natural gas devotees?
“Phenomenally,” says Mauger. “Personally, I don’t believe the
100-year number—it’s just the total amount of gas in place divided
by today’s consumption. Even if prices were to rise and make some
of the marginal fields economic then we are looking at a number,
which is substantially lower than that.”
His group has modelled what would happen if the “Prentice rules”
were applied to the United States. “We would see an incremental
30 [bcf] to 35 bcf [billion cubic feet] a day by 2025 or 2030,” says
Mauger. “To put that into perspective, we currently consume in
North America around 20 bcf a day for electrical generation, so if
you want to replace all the coal plants, you’d have to take today’s 20
bcf up to 50 bcf a day.”
On top of that, he adds, Ziff Energy’s analysis assumes growth of
electrical demand that would need to be covered by gas to be an-
other 10 billion to 15 billion cubic feet per day by 2025.
Egan feels the long-term supply picture still looks good. “The fact
is, more gas is being found,” he says. “When I talk to producers I get
no sense they feel they have exhausted finds. That’s a good signal
for continuing low prices.”
Moreover, the infrastructure in North America is robust, which
contributes to stable prices in the long term.
“And if hydrates can be made economic, that will be incredible—
Japan has plans to commercialize hydrates very soon. We’ve got
that stuff in extraordinary quantities; it bodes well for gas as a foun-
dation rather than a bridge. The way we talk about it is we do see it
as a foundation fuel, and I don’t see that changing in the foreseeable
future. I’m not a believer that we will go off hydrocarbons in my chil-
dren’s lifetimes. Gas is just too effective a fuel source. It’s the right
fuel in the right place at the right time.”
So from Mauger’s view, is natural gas a bridge to an alternative fuel?
“Yes, it has to be,” he says. “The question is, over what time
frame?” Is there something on the horizon that could cost- effectively
replace natural gas? “No, at least not one that can meet environ-
mental standards.” ■
“In the short to medium term [natural gas is] really the fuel
of choice. We have found a negative correlation between
natural gas prices and electrical generation using gas.
The reason behind that is natural gas can be used for
peak shaving or peak generation....”— Simon Mauger, Director of Gas Services, Ziff Energy Group

Participation in more than 9,000 shale wells worldwide shows that sustainable results are achieved when the reality of vertical and lateral shale heterogeneity is addressed in drilling, evaluation, and completion programs. When you determine the best reservoir quality and achieve the best completion quality, you maximize production, decrease cost, and ultimately tap into more productive intervals.

Explorers are putting together the technologies to optimize light tight oil developments in western Canada
By Darrell Stonehouse
Efforts to exploit tight oil resources began in the Bakken formation
in North Dakota and Montana over a decade ago. Explorers ex-
tended the effort north to Saskatchewan and it has now moved west
into a number of legacy fields across Alberta and Saskatchewan.
Along the way, the horizontal drilling, multi-stage fracturing and as-
sociated technologies have been advanced and adapted to optimize
exploration and production.
PetroBakken Energy Ltd. has been a pioneer in evolving the tech-
nical know-how to exploit light tight oil. Company president and
chief operating officer Gregg Smith outlines how the technology
used to produce the Bakken has changed over the years.
Smith says the company first used extended reach horizontals in
the play to expose as much of the reservoir as possible. Production
in the wells came in at 10-30 barrels per day. These wells were fol-
lowed by open-hole coiled-tubing fracture treatments, which pro-
duced at around 100 barrels per day. The problem with this system
was fracture heights were difficult to control, which resulted in water
incursion from an overlying zone, and saline/brackish water cuts
were as high as 75 per cent within five months.
Then, about five years ago came the multi-stage fracturing revo-
lution, led by Calgary-based Packers Plus Energy Services Inc. The
Packers Plus ball-drop system provided the ability to do multiple
fracture stimulations quickly and without multiple coiled-tubing trips
used with earlier technologies.
Production per well in the Bakken quickly increased. The extended
horizontal wells stretched up to 1,400 metres, and early multi-stage
treatments averaged seven or eight per well. Wells came on at around
200 barrels per day of initial production. With the ability to effectively
control fracture heights, water cuts were also minimized.
“We discovered by playing with the technology that more fracs
equalled more oil,” Smith says. “But the only way to increase the
fracture density at the time was to drill shorter wells. The interest-
ing thing that came out of drilling the shorter wells was that with the
same number of fracs that we used on the long wells, the short wells
performed initially at exactly the same or slightly higher rates—again
taking us to the conclusion that more fracs make more oil.”
PetroBakken began drilling 600-metre horizontal legs and placing eight
40-tonne frac stages per well. From there, Smith says as the multi-stage

fracturing technology evolved the company was able to increase fractur-
ing density over longer horizontal legs, yielding increased recoverable re-
serves. The company was the first to execute a 20-stage fracture in the
play. Well production has increased to up to 250 barrels per day.
“We saw some operators starting to drill two long horizontal wells
on each quarter-section,” he adds. “We thought if that’s the way the
play is going to go, we need a more capital-efficient way to do that.”
PetroBakken came up with a scheme to drill bilateral wells off of a
single vertical well to cut costs.
“In the subsurface, it’s exactly the same impact. That’s the conclu-
sion of the reserve auditor,” explains Smith. “If you add a second hori-
zontal leg the reserve auditor says it results in an increase of 50 per
cent of the reserves the original well would have recovered. But with
the bilateral wells there are tremendous capital efficiencies. A bilateral
costs $2.58 million to drill while it costs $4 million to drill two wells.”
While light tight oil is now commercial, the technological evolu-
tion of drilling and completions hasn’t stopped. As the Bakken has
matured and explorers have moved into new tight oil plays, other
technologies are being tested.
Many operators are re-examining their well designs and switching
to a monobore design rather than the traditional horizontal layout.
Monobore wells maintain the same diameter casing from the inter-
mediate casing through the entire horizontal leg.
Albert Stark, vice-president of operations for Spartan Exploration
Ltd., told a recent tight oil conference the move to monobore well
designs combined with open-hole ball-drop multi-stage fracture
completions is part of an ongoing effort to cut drilling costs.
Spartan operated 14 wells in the Pembina Cardium in 2010,
and all were monobores. Using the design saved Spartan around
$160,000 per well, or 10 per cent of drilling costs.
Stark said the monobore design combined with the ball-drop
system isn’t without its challenges. Debris issues in the wells re-
sulting from milling out the staging tool and wiper plug can lead
to fracking issues. So proper milling procedures must be fol-
lowed. Despite the debris concern, the company plans to con-
tinue use of the monobore design.
Explorers are also testing different completions technologies with
the goal of exposing more rock and increasing production.
Penn West Exploration has become a dominant player in the
Cardium light tight oil play around Drayton Valley, in west-central Alberta.

ENERGY EVOLUTION II // 21
LIghT TIghT OIL
Robert Hawkes, team leader for reservoir services at BJ Services,
told a recent Society of Petroleum Engineers meeting in Calgary
the ball-drop system designed by Packers Plus, now used by most
major service companies, has proved itself in tight oil plays across
western Canada and beyond. Packers Plus has used the system
in over 5,200 wells and completed over 45,000 fracture stages. BJ
Services has used the ball-drop system on 1,400 wells, completing
almost 13,000 stages.
Hawkes said the ball-drop system has a number of advantages. It
can complete more than 22 stages and allows for continuous pumping.
The entire open-hole wellbore has contact with the reservoir. Using the
system, crews can isolate out undesirable intervals. And most import-
antly, the system can complete multiple zones in a single day.
The downside of the ball-drop system is it becomes expensive
when more than 20 zones need to be fractured. On some occasions,
costly cleanouts are needed for the system to function, and the ball
sets need to be milled out for well interventions or production work.
Still, Hawkes said, “the ball-drop multi-stage fracturing system has
proven to be a workhorse system in horizontal completions in Canada.”
A competitor technology used in the tight oil completions mar-
ket is the pump-down wireline gun and plug system. In this system,
anywhere from three to 10 perforating guns are lowered to the per-
forating depth using the frac pumps and fluid. A composite plug is
run with the assembly to isolate the lower intervals to be fracked.
Then the assembly is moved to the next interval.
Hawkes said the advantages to this system are that it is efficient,
low-cost and provides for exact depth control. The downsides are
the need for extra fluid pumping and the risk of fishing operations if
the plugs or perforating guns fail.
Annular fracturing techniques are also gaining momentum in light
tight oil plays. With annular fracturing, coiled-tubing units are in the
wellbore during the fracture treatment. Abrasive perforating is used,
rather than charges, with a nozzle spraying a concentrated stream
of abrasives into the formation.
Sand plugs are used for isolation to fracture the different inter-
vals. Two big advantages of using sand plugs are they work with ce-
mented liners and there is no limit to the number of stages that can
be drilled, said Hawkes. Their downside is they are slower than ball-
drop systems, the annulus is bull-headed on each frac and pressure
has to be maintained on the plug to keep it in place.
To overcome this, packers can be used to replace the sand plugs.
The problem? Exxon Mobil Corporation owns the patent on this
technology and there is a six-stage limit in Alberta and a three per
cent royalty for using the system.
BJ Services has completed over 200 wells using abrasive perfor-
ating and has fractured as many as 40 stages in a single trip.
“Abrasive perforating and annular fracturing are becoming the
method of choice in the Bakken, Viking and Cardium formations,”
said Hawkes.
Operators are also taking a new look at the type of fracturing flu-
ids being used in light tight oil formations. In the Cardium, produ-
cers have been using oil to carry proppant deep into fractures.
But Spartan’s Stark says many are now looking at water-based
fluids as a means of reducing costs. The two main systems being
tested are a nitrified surfactant gel and the slickwater (typically 98+
per cent water and sand) common in tight gas stimulation. Stark
said the cost difference between the used oil frac system designed
by Trican for the Cardium and water-based fluids is around $94,000
on an average well. Other systems being tested include foamed
water fracs, nitrified oil fracs and gas fracs.
“The preferred system may ultimately be determined by well per-
formance rather than cost,” said Stark.
Microseismic technology has also played a key role in the ex-
ploitation of tight oil plays, and the tool is evolving as field de-
velopment accelerates. Microseismic uses geophones on the
surface, buried near the surface, or inserted via wireline into
existing wells, where available, to measure the tiny seismic ac-
tivities created during hydraulic fracturing. From there, the data
is interpreted and mapped, showing the penetration and direc-
tion of the fractures. The information is delivered in real time.
Operators can adjust their fracking stimulation program as it ad-
vances stage by stage down the length of the horizontal wellbore,
based on the information generated.
Microseismic was first used on individual wells to understand how
fractures move within the reservoir under stimulation. In the Bakken,
the goal is to keep fractures out of the overlying Lodgepole formation,
which is saturated with saline/brackish water in many locations.
A new technique, pioneered by MicroSeismic, Inc., uses an array of
buried geophones to monitor entire oilfields passively. Last March, the
company installed a buried array system for Whiting Oil & Gas Corp.
covering 150 square miles in the Bakken play in North Dakota. With
1,200 geophone channels in place, the system will enable microseis-
mic monitoring, mapping and analysis of the hydraulic fracturing
operations for Whiting’s Sanish Field development program. It will
also permit Whiting to monitor the primary, secondary and tertiary
activity in a variety of reservoir conditions for its Bakken and Three
Forks formation wells on a long-term basis. ■

The ensuing global recession turned out to be a lot like a trusty com-
puter reboot. It reset the money markets, economic outputs and ener-
gy supply and demand algorithms. A new cycle began and the fuel of
choice for this new, more cautious cycle of economic growth in North
America, at least, seems to be clean-burning natural gas from shale.
As oil prices, at the bottom of the recession, began their relentless
upward march to the current US$100 per barrel mark, natural gas prices
have remained flat in the range of US$3 to US$4 per thousand cubic feet.
This reflects the disparity between the vast supplies unleashed by shale
gas development in North America and the yet-to-be-tapped demand to
take advantage of this incredible resource, estimated at 4,471 trillion cubic
feet in place just on this continent. To put that in perspective, Canada’s
total consumption in one year is about three trillion cubic feet.
Decades of innovation and perseverance have succeeded in unlocking
natural gas from the world’s most common rock formation and launched
a paradigm shift in supply. Natural gas production has been declining for
years in Canada and for decades in the United States, but now it’s in as-
cent. A relatively low-cost energy source, shale gas currently adds about
10 billion cubic feet per day of production. By 2020, its production is ex-
pected to grow to 24 billion cubic feet a day.
And this has game-changing implications.
ProduCerSThe meteoric rise of shale gas opened a new frontier of growth for
producers. The technology that unlocked shale gas—horizontal
drilling coupled with multi-stage fracture stimulations—emerged in
its current incarnation shortly after U.S. independent Devon Energy
Corporation entered the Barnett shale in Texas in 2002.
Devon Energy showed shale gas was commercial and repeatable.
Soon, other companies joined the play and, just as quickly, they found
Barnett analogues in other shale basins in the United States and
Canada. In British Columbia, companies like Encana Corporation and
Apache Corporation secured first-mover advantage in the Horn River
shales, picking up vast, low-cost contiguous tracks of the most pro-
spective lands for this production -style resource play development.
Producers that waited later paid their way into these plays.
There were also some eyebrow-raising attitude shifts along the way.
Talisman Energy Inc., for example, displayed a Saul-to-Paul transformation as
one top executive, Jim Buckee, who shunned resource plays, retired and was
replaced by John Manzoni, who steered Talisman straight into the Montney in
British Columbia and the Marcellus shale basin in the United States.
But what definitively announced to the world the importance of shale gas
was Exxon Mobil Corporation’s purchase of shale gas maverick XTO Energy
Inc. for a whopping $41 billion in December 2009. Exxon Mobil, arguably the
closest entity to a U.S. national oil company, faced with declining conventional
reserves and seemingly limited growth prospects worldwide, sailed into new
reserves and growth with its embrace of shale gas.
“Today all the major producers are in shales,” says Mike Adams, Talisman’s
senior manager of corporate projects and business development. He spoke
at the Canadian Institute’s seventh annual Shale Gas Symposium in Calgary
last January. “Unlike the oilsands, where some majors are not playing for
whatever reason, they’re all there in the shales.”
Adams tracked some 97 shale gas transactions worth a total of
about $100 billion in the last two years in North America. And new en-
trants are coming to North America’s shales—the Chinese, the Japanese,
the Koreans.
Adams notes that the North American shale gas business has also
changed hugely over the last two years and continues to reshape itself.
“There’s going to be lots of activity. There’s going to be more consolida-
tions because it’s a scale business. It’s hugely capital intensive and it will
need well-capitalized companies,” he says.
GLoBAL CoNTexTThe natural gas abundance story in North America seems well
understood now. Various estimates suggest the continent has more
than 100 years of natural gas supply. By 2030, more than half of

its natural gas will come from unconventional sources—mostly
shales—according to World Energy Council forecasts.
And what works in North America stands a good chance of working in
other parts of the world. The biggest producers are now looking to under-
stand the global potential for shale gas.
Drawing upon the data collected by U.S.-based Core Laboratories N.V. for
its Global Shale Project, Randy Miller, Core’s president of integrated reservoir
solutions, says 2011 will see much assessment work and many pilot wells
drilled worldwide. The areas that have traditionally seen oil and gas develop-
ment and benefit from existing infrastructure will be the first in line.
“But, right now, Poland is certainly where most of the activity is going
on outside of North America,” Miller says. “A lot of acreage has been taken
out by various companies. The major players there are ConocoPhillips,
Talisman, Chevron [Corporation], Marathon [Oil Corporation], Lane Energy
[Holdings plc], BNK [Petroleum Inc.], Exxon Mobil, Shell, Eni and others.”
Strangely enough, Russia, which has the world’s largest in-place shale
gas potential, according to the World Energy Council, has been throwing cold
water on the shale gas revolution. Its top officials have dusted off Cold War–
era rhetoric and cast doubt on the significance of foreign shale projects. State-
owned Gazprom’s executive chairman Alexey Miller has been reported saying
shale gas should be regarded only as a “temporary local source” of hydrocar-
bons that will never become a major global energy sector.
Then he tipped his hand, adding “shale gas will never compete with
traditional gas,” which Russia has plenty of and has a vested interest in
continuing to supply to countries like Poland, which currently is entirely de-
pendant on Russia’s conventional gas.
redrAWiNG The eNerGy mAPFaced with natural gas declines and growing demand prior to shale
gas, the United States started building up its liquefied natural gas
(LNG) import capability in the last decade. Many of those projects
came to completion just as growing shale gas production hit the
market. Shale gas turned out to be cheaper than LNG so the North
African and Middle Eastern LNG producers that were eyeing the
United States as a potential market have today largely redirected
their marketing efforts back to Egypt, Japan, Europe and Asia.
The combination of large U.S. shale gas resources and current low nat-
ural gas prices in North America has even prompted discussion around
converting some United States. LNG terminals into liquefaction facilities
to export natural gas. While some consider that even a small volume of
exports could open a window to world-level natural gas pricing and shore
up the low North American price environment, the downside is that lique-
faction facilities aren’t cheap, they take time to build and, perhaps most
importantly, the export idea is at loggerheads with U.S. political objectives
of energy security and reducing reliance on foreign energy.
NeW mArkeTSThe oil and gas industry itself admits that commodity prices languish-
ing in the doldrums of US$3 to US$4 per thousand cubic feet aren’t
sustainable for most shale gas production. Prices need to be closer
to $5 and $6 per thousand cubic feet over the long run. So what is the
answer to firming up North America’s natural gas price environment?
It’s finding new markets for natural gas in North America.
Transportation may be a part of this. Transportation represents roughly
one-quarter of North America’s energy usage, so expanding natural gas
penetration in this market would certainly help the supply and demand
balance. California is at the forefront of using natural gas as a transporta-
tion fuel largely due to its pollution problems, which have brought in en-
vironmental legislation and incentive programs to get more clean-burning
natural gas vehicles on the road.
In Canada, Encana has taken up the challenge of reigniting inter-
est in natural gas vehicles. (Canada was one of the first countries to
develop natural gas vehicle technologies in the 1980s and 1990s and
found markets around the world; uptake at home, however, has been
slow, to say the least.) So Encana is telling the shale gas abundance
story and working with Canada’s NGV association and the NGV

equipment manufacturing industry to promote wider usage of natural
gas in transportation.
The transportation sector, however, has only limited potential for moving
North American natural gas prices. “Even if we had 10 per cent NGV pene-
tration each and every year,” says Simon Mauger, director of gas services for
Calgary-based consultancy Ziff Energy Group, “we would end up with one
[bcf] or two bcf [billion cubic feet per day of incremental] demand. So natural
gas for vehicles really is not the answer. From a pollution perspective, from
reducing reliance on external oil, it’s not a bad idea. But going from nothing to
next to nothing [in demand] doesn’t make for much of the market.”
The real potential for increasing natural gas demand is in power gen-
eration. Building coal plants in today’s carbon-wary world is a tough sell.
Alternatives such as wind power are growing, but they currently supply
only about two per cent of North American energy needs. According to
Ziff, this may grow to over six per cent during this decade, but that still isn’t
particularly significant. So relatively clean-burning natural gas in power
generation has the most potential for growth.
“The U.S. fleet of coal plants, which provides 50 per cent of their
power generation, is aging, particularly here in the Midwest and the
Southeast,” Mauger says. “If we were to replace those coal plants as
they end their economic life at the end of this decade or [over] the next
15 years, we would need an incremental 30 [billion cubic feet] a day of
natural gas. So this is the real wild card in how shale fits into the eco-
nomic picture of North America.”
deCLiNiNG exPorTSWhat has been good for the United States hasn’t been so good for
Canada. Canada produces more gas than it consumes and exports
the rest. Largely as a result of shale gas, Canadian natural gas ex-
ports to the United States have been declining and so has Canada’s
overall natural gas production.
From a high point of about 15.8 billion cubic feet per day of production in
2008, Canadian production has been losing about a billion cubic feet per day
each year. The National Energy Board expects that 2010 production, when the
figures finally come in, will have dipped to about 13.04 billion cubic feet per day.
AJM Petroleum Consultants’ vice-president of geoscience, Dave Russum,
explains some of the economics behind this decline. He says natural gas
prices have come down while the Canadian dollar has strengthened. Because
many Lower-48 shale plays are on the doorstep of densely populated natural
gas consuming regions, they have, in some cases, a competitive advantage
over Canadian natural gas exports. That advantage can mean as much as a
$1 per thousand cubic feet, according to other analysts.
The marvellous Marcellus in Pennsylvania is a case in point. This hugely
prolific formation of the Appalachian Basin currently produces 2.5 billion
cubic feet a day, has a fairway as large as all the other producing shales
in North America and sits next to the massive U.S. Northeast gas market.
It also happens to be the most economic play, with sub-$3 per thousand
cubic feet costs, according to Ziff Energy.
Even Canada’s Montney, a shaley tight reservoir play in north eastern
British Columbia that once boasted the best gas economics in North
America, lags Marcellus’ prowess.
“Then we have the added challenge of [the United States] being able to
bring in cheap imports of LNG when it’s available on the import market,”
Russum says.
It gets worse for Alberta.
Historically, 60-70 per cent of Alberta’s activity came from the gas sec-
tor—conventional gas, shallow gas, tight gas and more recently coalbed
methane, all of which are less economic than the best shale gas plays.

A thin stream of shale gas has been produced in the United States in
the Appalachian and Illinois basins for almost 100 years. But it wasn’t
until George Mitchell turned his attention to the Barnett shale in the early
1980s that the modern era of shale gas development got underway.
Aided by a U.S. tax incentive to stimulate exploration and develop-
ment of unconventional resources, Mitchell spent almost a decade
and millions of dollars in research. He cycled through an array of
drilling and completions techniques, all the while ignoring a chorus of
industry veterans who told him he was wasting his time.
Challenging conventional wisdom that shale can’t be fractured
by water, Mitchell and his team eventually met with success in the
early 1990s using a high-volume “slickwater” fracture stimulation,
which drastically reduced fracking costs by eliminating the frac
gel component and reducing sand.
But it would still be more than a decade before the floodgates
on Barnett shale gas burst open in 2002 when U.S. independent
Devon Energy bought Mitchell Energy & Development for $3.5 bil-
lion. Devon Energy paired slickwater fracs with horizontal drilling
and shifted shale gas development into high gear.
The Barnett would become one of the largest natural gas fields
in the United States. More importantly, it showed the world that
the vast natural gas resource locked in shale and tight unconven-
tional reservoirs could be tapped commercially.
Ongoing technical innovations in open-hole and cased-hole
multi-stage completions allowed better fracture stimulation con-
trol across the length of a horizontal well and continued to improve
shale gas economics. Producers also migrated this technology to
other unconventional reservoirs, both gas and oil bearing, finding
commercial production across the continent.
Today, the list of shale plays runs long. Some of the high-flyers
are the Haynesville, Fayetteville, Marcellus, Horn River, Montney,
Eagle Ford, Utica, Bakken, Viking, Lower Shaunavon, Cardium and
Niobrara. Others are in the making. But all of them can be traced
back to the determination and perseverance of George Mitchell,
who, at 92 years of age, still remains active in the industry, both as
a driller and the largest shareholder in Devon Energy.
The National Energy Board expects Alberta’s gas production to dip to 8.5 bil-
lion cubic feet per day in the next two or three years from 12.7 billion cubic feet per
day in 2009. British Columbia may pick up some of this contraction, growing to
3.7 billion cubic feet per day from the current 2.7 billion cubic feet per day.
What this means for Alberta is fewer natural gas jobs and perhaps
tighter government budgets since it remains to be seen whether Alberta’s
growth in oilsands and the current boom in light oil drilling using the same
technology that unlocked shale gas will make up the slack in workforce
and government revenues.
oTher imPLiCATioNSDeclining conventional gas production in Alberta is making Alberta’s
petrochemical industry nervous. For years, it benefited from low gas
prices because its natural gas liquids–derived feedstock gave the
industry a competitive advantage compared to high–priced crude
oil–derived naphtha feedstocks used by other petrochemical hubs.
But currently, there is a glut of global petrochemical capacity. And
when world demand picks up, it’s unclear whether Alberta’s petro-
chemical industry will be able to source enough liquids-rich natural
gas to drive growth and profitability.
Falling Canadian gas exports have also recently prompted TransCanada
PipeLines Limited to hike its tolls for moving natural gas across its mainline
system to the east. This is a further handicap on the competitiveness of west-
ern Canadian gas exports, but Steve Clark, TransCanada’s vice-president,
commercial-west, Canada and eastern U.S. pipelines, sees this only as a tem-
porary issue. Speaking at a Vancouver gas conference, he expressed opti-
mism for the prospects of a gradual comeback in conventional natural gas
production as gas prices strengthen towards the middle of the decade.
The huge potential of shale gas has also pushed frontier gas prospects to
the sidelines. Plans for a Mackenzie Valley pipeline have been discussed for
more than 50 years. In the years leading up to the financial markets’ collapse,
the prospects of finally building the pipeline never looked better, despite the
protracted regulatory process around its social and environmental impacts.
But then the recession hit and shale gas came on. In March, Ottawa cleared
the way to its construction, but analysts don’t expect much to happen on the
Mackenzie Valley pipeline until the end of this decade.
ChALLeNGeSWater usage and groundwater contamination top the list of challen-
ges facing shale gas development. Some jurisdictions have intro-
duced frac fluid chemical disclosure requirements and want the
industry to better account for its use and disposal of water.
The industry has responded by cleaning up its frac fluids. Some frac pro-
viders have replaced diesel carrier frac fluids with food-grade mineral oils to
reduce potential impacts. Others are reducing or even trying to eliminate oil
carriers altogether. Some are looking to non-potable water sources in frack-
ing. And mechanical processes are replacing chemicals where possible—for
example, in the treatment of frac water to control microbial growth.
“The challenge is economically extracting shale gas in an environmental man-
ner,” Russum sums up. “All the shale plays are different. The Barnett shale is sig-
nificant for being the first and providing guidance for other shale opportunities.
The Haynesville is the deepest. The Marcellus, a game changer in terms of price.
The Horn River, quite possibly the biggest of the shale plays. But even in some of
the best [shale] plays in North America, producers are not guaranteed to make
money. We have to encourage science and experimentation to find the optimal
solutions in specific plays. Perseverance and patience are to be vital.” ■

to a predetermined point above the shale gas

an increasing angle until it meets the reservoir
interval in a horizontal plane. See Figure 1.
Once horizontal, the well is then drilled to
a selected distance, which could extend as
much as 2,500 metres. This portion of the
well, called the horizontal leg or lateral, allows
significantly increased contact of the wellbore
with the reservoir compared to a vertical well.
hyDrAuLIcFrAcTurINGHydraulic fracturing is the process of
transmitting pressure by fluid or gas to
create cracks or to open existing cracks
in hydrocarbon-bearing rocks many thou-
sands of feet underground. The purpose
of hydraulic fracturing an oil or gas reser-
voir is to enable the oil or gas to flow more
easily from the formation to the wellbore.
Hydraulic fracturing is not a new process
and engineering principles are well under-
stood. See Figure 2.
Multi-stage fracturing, the latest evolution
in hydraulic fracturing, involves the segmenta-
tion of fracturing operations in the horizontal
leg of the wellbore. Each stage is isolated
using either plugs or packers so that fracture
energy, applied to the wellbore from the sur-
face fracturing equipment, is concentrated
within each stage. The result is the creation
of extensive fracture patterns that allow the
oil or gas to flow more easily to the wellbore.
Stimulation procedures are applied to each
stage individually. See Figure 3.

observe the development of vertical and hori-

time. Measurement of microseismic events
that are occurring as the fracture stimulation
takes place is important because adjustments
can be made during the operation to ensure
that the fractures created stay within the zone
that has production potential.
Once completed, the microseismic model
can be used to define the limit and reach of
fracture stimulations in each wellbore and al-

Industry has a strong track record of safe
development, demonstrated in hundreds of
thousands of wells drilled throughout North
America during the last 50 years. Still, the
reality is that there are challenges associat-
ed with the level of public anxiety, specific-
ally where hydraulic fracturing is concerned.
Canadian regulators and the natural gas
industry are focused on the protection of
surface and groundwater. A key element
of successful hydraulic fracturing is proper
well construction, which will ensure that
groundwater is isolated from the wellbore
and protected from completion and produc-
tion operations. See Figure 4.

There is now tough competition in North American gas mar-
kets, and the legendary successes of junior oil companies in
the province—a crowning achievement of western Canada’s
way of doing business—is in decline. Juniors can’t be really
small any more, because they now generally require a lot of
start-up capital. Crashing gas prices have put some junior oil
companies into receivership, forced many to merge and forced
all to change.
Perhaps Winter Petroleum Ltd.—a small, privately held com-
pany—typifies the situation for little gas producers. With operations
in the northwestern corner of Alberta, the company got its name be-
cause its properties can be drilled only during the winter, according
to president Duncan McCowan, a geologist.
“Winter drilling requires a lot of equipment, and it’s expensive,” he
says, “and our production is remote from major markets. Because of
cost structure and transportation, we’re finding it tough to compete
in U.S. markets.”
His company hasn’t let any employees go, however. “We are still
slightly profitable, but we can’t grow. We’ve cut back our capital
spending completely and many of our operational items, too. [Dry
gas] activity in that part of the province is at a standstill.”
McCowan points to a decline in the number of junior companies,
partly through bankruptcies like that of Drake Energy Ltd., which
was a neighbour to his own gas company.
“Today, you need pretty serious money for a start-up. A few mil-
lion dollars won’t go very far anymore, because the new technolo-
gies we’re using involve horizontal wells and multi-stage fracking.
It used to be you could drill a well for a couple hundred thousand
dollars. Today it takes millions, and financing groups are putting
together a fund of, say, $35 [million] to $70 million and then putting
an experienced management team in charge. There are fewer mom-
and-pop petroleum companies around.”
Peter Tertzakian of ARC Financial Corp. says two other important
trends favour consolidation and larger companies.
“Bulking up to get costs down helps you deal with lower prices. It
gives you economies of scale. A related factor is that a lot of com-
panies are migrating to horizontal drilling and completion strategies,
but that’s very expensive.”
On average, those wells cost $4.5 million, and there have been
many wells that cost $8 million or more. “By drilling fewer wells that
are more expensive each, you need more backbone—you need to
be a bigger company.”

The companies most at risk are those that are heavily lever-
aged and biased to natural gas, but many of the smaller ones
are successfully implementing what he calls “revitalization
strategies: shif ting their focus to l iquids-rich gas, or even
prospecting for oil. A small amount of liquids in the gas stream
can make a big difference,” since it often has a greater market
value than oil.
Compare that situation to the one announced in February, when
PetroChina Company Limited made a huge counterintuitive deal
with Encana Corporation. While other major Asian investments
in the Canadian petroleum industry have mostly gone into the oil-
sands, PetroChina put its money into shale gas. The two compan-
ies announced that they had inked a $5.4-billion deal by which they
would become equal partners in Encana’s Cutbank Ridge gas field
in British Columbia. This investment, which surpasses Sinopec
Corp.’s $4.65-billion acquisition of ConocoPhillips Company’s stake
in Syncrude Canada Ltd. last year, is Asia’s largest single bet on
North America’s energy sector.
According to Encana spokesman Alan Boras, the focus of this ef-
fort is natural gas, not the associated gas liquids.
“We are always looking for ways to maximize the value of our
assets, and natural gas liquids extraction is an important part of that
process,” he says. “However, that is not our major focus.”
Since the company does not see natural gas prices above $6.63
per thousand cubic feet in the foreseeable future (2021), Encana
clearly is basing its business plan on something other than an up-
ward move in North American gas prices.
One of those ideas is low-cost production. According to Boras,
“In the Montney, where we have done the deal with PetroChina, our
wellhead cost is about $3.15 [per thousand cubic feet].”
The deal will enable the Chinese to “get an early return on their
investment, and then take the technology back to China to use it
there. That certainly is part of what they’re thinking. The Chinese
have recently talked openly about their need to increase domestic
gas use,” says Boras.
In addition to low-cost production, new pipe in a region already
riddled with infrastructure could lower future transportation costs.
This is the significance of the National Energy Board’s recent ap-
proval of TransCanada Corporation’s plan to build a $310-million
pipeline to connect British Columbia’s Horn River shale gas region
to its Alberta mainline system.
ASCeNdANCy?While the gas industry isn’t exactly in the ascendant, some trends
suggest that ascendancy might not be far off. This isn’t readily ap-
parent, since shale gas has backed Canadian producers out of trad-
itional U.S. markets and driven down prices.
Low prices have made much of Canada’s conventional gas un-
economic in distant U.S. markets, and many producers are in
trouble. In recent years the only major commodity to decline in price
and stay there, natural gas has mostly defied winter demand for
heat and summer demand for air conditioning.
The price collapse is forcing the industry to dramatically restruc-
ture, clouding the outlook. Such legacy assets as Canada’s Arctic

gas fields look increasingly like white elephants: the likelihood of a
pipeline from north to south is slipping ever farther into the future.
According to Robin Mann, president of AJM Petroleum
Consultants, “Because of the development of shale gas formations
like Montney and Horn River and others with great potential right
next to infrastructure and pipelines, and with our existing conven-
tional gas and our exports to the United States going down daily, we
have more than enough [gas] for our own [use], so why is it import-
ant to build these pipelines? Why are we worrying about anything
north of Alberta and B.C.?”
Consumers are happy with lower prices. Companies are not,
however, and neither is the Government of Alberta—now into its
fifth-consecutive year of deficit budgets.
One Alberta politician with ideas on the issue is Wildrose Alliance
Leader Danielle Smith, who doesn’t have to worry about balancing
this year’s provincial budget. She sees the collapse in gas prices as
an opportunity.
“There is so much we can do now to increase demand: fuel switch-
ing, the Pickens Plan [to increase gas use in automotive transport] in
the United States, increasing use of gas for power generation.”
She even talks about installing modern-day gas-fired Stirling engines
in our homes to generate both heat and power. “If we do these things,
consumers win. So does the environment, and so do gas producers.”
In a way, those simple ideas describe a path that could bring the
industry out of its funk. They are also consistent with much of what the
industry is already doing in response to a rapidly changing business
environment.
One industry response has been to reduce natural gas drilling—at this
writing, at a one-year low. Companies are focusing instead on drilling for
oil. According to ARC Financial’s Tertzakian, “this capital migration con-
tinues to be a positive leading indicator for natural gas price recovery.”
The industry is also responding to low prices with rapid adapta-
tion of technology. It is cutting costs, seeking profitable niches and
developing better markets. In addition, consumers are responding
to the attractive price of natural gas and policy-makers are seeing it
as a low-carbon alternative to other fuels.
And North America’s dominance in shale gas development makes
it for the first time a potential large-scale manufacturer of liquids
made from natural gas.
GAS To LiquidSThe gas-to-liquids concept is most evident in the billion-dollar deal
Talisman Energy Inc. struck late last year with Sasol, the South African
petrochemicals giant. The deal involved selling a 50 per cent interest
in Talisman’s Farrell Creek shale gas properties in British Columbia.
Eventually, the partnership could develop a plant using Sasol’s gas-to-
liquids technology to turn the gas into a desirable liquid fuel. This is
proven technology: Shell, for example, is constructing a $6-billion gas-
to-liquids project in Qatar, the tiny Middle Eastern country with 15 per
cent of the world’s proved natural gas reserves.
Another way to solve the stranded gas problem is to create lique-
faction facilities for natural gas exports. When finished, the $3-billion
Kitimat LNG project will become another face in the global liquefied
natural gas (LNG) market—competing with, for example, Qatar.
According to Rosemary Boulton, the founding president of
Kitimat LNG, “we’re experiencing a bigger gas bubble than we have
seen in western Canada for 20 years, and this makes [LNG exports]
a particularly viable proposition. We need to develop LNG to meet
the needs of gas markets other than those in the U.S.”
Apache Corporation and EOG Resources, Inc. obviously agree,
since in December they bought out her start-up company—after it had
received development approvals—and Canadian gas giant Encana
Corp. came onboard with a 30 per cent interest this past March.
Countries like India and China will eventually begin developing
their own shale gas resources, but at present, “Japan and Korea are
the world’s biggest importers of natural gas,” says Boulton, “and
they have no indigenous supply.”
She adds that “there are a number of ways you can write a price
contract, and one of them is based on the price of WTI [West
Texas Intermediate]. That’s a pretty good price for exporters.
For importers, it’s a lot better than a contract based on the price of
Brent [North Sea] oil. Markets in Asia price natural gas relative to the
price of oil, so that could be very attractive.”
Bill Gwozd, a vice-president of Calgary-based Ziff Energy Group,
agrees. “If you have an Asian market that’s prepared to pay [an LNG]
price that’s linked to oil, we think [shale gas production] can surge.”
Boulton sees room for expansion of Canada’s international LNG
business. “The Kitimat project is approved for five metric tonnes or 700
million cubic feet per day. The pipeline will be capable of supporting
a much bigger project—doubling [project capacity] is certainly viable.”
She doesn’t see a lot of LNG shipments leaving from British
Columbia’s Lower Mainland, however. “Projects are all about loca-
tion. I see a lot of objections to a project [there] because of the na-
ture of some communities on the Left Coast.”
STAkehoLder eNGAGemeNTA year ago, American filmmaker Josh Fox released a film called
Gasland, which purported to document the dangers of hydraulic
fracturing for shale gas. One landowner after another talked about
the dangers of shale gas to their health, and some spectacular foot-
age showed a man setting water from his kitchen tap alight—the re-
sult, he said, of shale gas polluting his water well.
Ziff Energy’s Bill Gwozd is skeptical. While he acknowledges that
the consumption of large amounts of water for fracking can be an
environmental problem in areas where water is in short supply, he’s
not sure the environmental concerns expressed in Gasland really
hold much credence.
“Shale gas and groundwater are peanut butter and oil,” he
says. “They don’t touch each other. There are a lot of people who
want to talk about shale gas polluting groundwater but it just isn’t
going to happen.”
He points out that the geological zones that hold groundwater and
shale gas can be literally thousands of feet apart, and that dirt and rock
under pressure are anything but porous. “So how could deep zones of
shale gas pollute groundwater, which is maybe 1,500 metres up?”
“You’ve got to believe that the answer is in the details,” he says.
“A lot of people complain about shale gas development without
bothering to understand the technical issue. When you get into ›
ENERGY EVOLUTION II // 33

that conversation, they have to come to the conclusion that there is
no problem here.”
Well, not entirely. In March, Québec Environment Minister Pierre Arcand
said the government didn’t have enough scientific information about hy-
draulic fracturing to sanction its further use. Until his department com-
pleted its research into what had become a heated public issue, the
government would halt new drilling in Québec’s promising Utica shales.
Ziff’s Gwozd has a kind of conspiracy theory into public concern
about shale gas.
“Who’s driving the environmental objections?” he asks, rhetoric-
ally, then offers his own answer: “Anybody [with an interest in] con-
ventional gas, in LNG, in coal, in energy alternatives. If you complain
about it, you make it an issue. [To say these worries are based on
science] is like the fox telling the bird he doesn’t want to cook it for
turkey day.”
Enter Lane Wells, the principal at head•stock, a public consul-
tation firm specializing in issues affecting aboriginal communities.
Wells describes effective stakeholder engagement as involving
“thoughtful, non-adversarial and respectful exchanges of informa-
tion. Listening to stakeholders is important. Responding to what you
have heard is critical.”
Stakeholder engagement is becoming increasingly crucial if you
want public policies that give you the right just to develop shale gas.
ChANGiNG PoLiCyPublic policy is becoming ever more important in other ways, too.
The Obama administration, for example, is now behind a drive to
make natural gas the fuel of choice in as many energy-consuming
applications as possible, with an emphasis on switching coal-fired
power plants to gas.
Senior Democrats in Congress are getting behind the stuff, por-
traying it as an alternative fuel for transportation that can serve as
a stop gap until renewable sources of energy, like solar and wind
power, become economical on a broad scale.
Reflecting this policy, last year Rahm Emanuel—a congressman and
formerly President Barack Obama’s chief of staff—introduced legislation
that would have offered tax credits to both gas producers and consumers.
The legislation died with last fall’s election, which unceremoniously turfed
Emanuel and other Democrats from the House.
The promotion of natural gas as a fuel is popular within the indus-
try, also. The New York Times cites William M. Colton, ExxonMobil’s
vice-president for corporate strategic planning, as a serious natural
gas enthusiast.
“If there is any kind of major trend, we think it’s going to be a shift
toward more natural gas. Natural gas is available. It’s the most ef-
ficient way to generate massive power. It’s affordable. We already
have gas infrastructure in place. From a CO2 emissions standpoint,
it’s 60 per cent cleaner than coal, and [the United States has] 100
years of supply.”
As these issues get resolved, a leaner and meaner industry using
advanced technologies and far more capital is emerging. The industry
is opening its collective eyes to a brave new world of natural gas—one
in which surplus supplies are convulsing the sector in many ways.
“Our intent is to tough it out,” says Winter Petroleum’s McCowan.
“So we’re doing creative things to cut costs—jointly handling gas
with our neighbours, for example. We’re optimistic about our geol-
ogy—the horizontal potential is huge, but we couldn’t justify [hori-
zontal drilling] in this price environment. Sure, we’re pessimistic
about gas prices, but we know they’re going to turn. We don’t know
when, but when they do, we think it’s going to be pretty quick.” ■

With growing confidence the province’s massive shale resource can
be technically produced, efforts are now under way to build the infra-
structure needed to find premium markets for expanding production.
Encana executive vice-president and president, Canadian div-
ision Mike Graham told a BMO Capital Markets conference earlier
this year that Encana is making great strides in driving down costs in
its B.C. shale plays, making them among the best on the continent.
“Technology has moved very, very quickly there,” said Graham.
“And there’s still a lot more to come.”
In the Montney, Graham said wells have gone from 1,000-metre
to 2,000-metre horizontal legs, and the latest wells are extending
out to 2,500 metres. Six to eight wells are being drilled per pad. The
company is now fracking up to 14 intervals per horizontal leg.
“Average wells are now initially producing over five million cubic
feet per day and up to 10 million cubic feet per day,” he added, not-
ing the company’s cost per interval completed has declined from
$500,000 to $350,000. “We may get as much as 0.5-0.8 billion cubic
feet in reserves per frac stage. Our finding and development costs
are getting below $1 per thousand cubic feet, and our supply costs
are down from $5 to $6 to $3 and are probably going to be sub-$3
this year. So even at today’s prices, we still make a really good re-
turn on the Montney.”
Encana’s next hurdle at the Montney is stripping liquids out of the
gas stream, in an effort to improve the economics of the play further.
“Right now we’re selling the liquids in the gas stream without
stripping them out,” he explained. “But we’re going to take our NGL
[natural gas liquids] from 10,000 barrels per day in Canada right up
to 30,000-35,000 barrels per day over the next few years.”
The increase will come from the Montney, along with Encana’s other
resource plays in the liquids-rich areas surrounding the Deep Basin.
Talisman Energy Inc. is also making major progress on its
Montney tight gas and shale play at Farrell. Talisman has eight rigs
operating in the play in 2011, and expects production to reach 50-60
million cubic feet per day net to the company.
“At Farrell, we have over 1,400 well locations,” Talisman executive
vice-president, conventional, Jonathan Wright told a First Energy
conference in March. “Wells to date have had initial production
averaging six million cubic feet per day and are expected to recover
seven billion cubic feet of gas.”
Further north in the Horn River, Encana’s Graham said gains from
technological advancements continue driving down costs. A key factor in
this is the pad drilling, or gas factory, concept pioneered by the company.
“We’re now drilling as many as 16 wells off of one pad. It gives us
a lot of economies of scale and it’s what’s driving down our costs,”
he explained. “We do this in an enormous way in the Horn River.
We’re getting very good at it.”
Graham said the goal at Horn River is to maximize everything—
the number of wells per pad, the length of the horizontal legs, the
number of fracs per well and the size of the fracs themselves. On
its latest wells, horizontal legs are now stretching as far as 3,000
metres, and Encana is averaging 27.5 fracs per well. The size of the
fracture treatments have grown from 4,000 cubic metres of water
per frac to 5,000 cubic metres and pumping costs have declined
from $176 per cubic metre to around $119 per cubic metre. The
company is now putting in around 75 fracs per section.
“Costs have continued to come down to around $500,000 per frac,”
said Graham. “Finding and development costs are getting down to the
80- to 90-cent range. What we’re finding is the more fracs we put into
these, the bigger the wells are. On our 63K pad, the average initial pro-
duction is between 10 [million] and 15 million cubic feet per day with
some wells coming in [at] over 20 million cubic feet per day.”

“In unconventional gas,unlocking the sweetspot, while mitigatingwater concerns, isbusiness as usual.”
REgIONAL dEvELOpmENTS
With wells on production for a number of years, the company
is also getting a better understanding of decline rates in the field.
Graham said wells are declining around 55 per cent the first year, 35
per cent the second and 20 per cent the third.
“So after two years they are still producing over five million cubic
feet per day. We think we are going to get estimated ultimate recov-
eries based on existing declines of 20 billion cubic feet per well,” he
added, while cautioning that it is still “early days” in the play.
Infrastructure to process the gas is taking shape with the
400-million-cubic-feet-per-day Cabin gas plant operated by
Encana, Spectra Energy Corp.’s reworking of its Fort Nelson plant
to bring capacity back up to one billion cubic feet per day and a
new take-away pipeline being built by TransCanada Corporation
in the works.
But the bottom line when it comes to driving further growth in B.C. shale
plays is finding new markets for the gas. With U.S. shale plays growing
quickly, finding a home for increasing Canadian production is paramount.
According to industry studies, recent B.C. discoveries indicate
the province will have the resource capacity to more than double
current production of about 2.8 billion cubic feet per day to more
than seven billion cubic feet per day in the next seven to 10 years.
Producers in the Horn River are working to build an export line
and liquefied natural gas terminal in Kitimat in one effort to relieve
the pressure. In mid-March 2011, Encana acquired a 30 per cent in-
terest in the planned terminal, located on the west coast of central
British Columbia, and the associated natural gas pipeline, in an ef-
fort to move gas to Asia-Pacific markets. Apache Canada Ltd. and
EOG Resources Canada Inc. own the remainder of the facility.
“We expect that this project will help advance North America’s
natural gas economy across the Pacific to markets where demand
is growing and natural gas prices are more closely tied to oil prices,”
said Randy Eresman, Encana’s president and chief executive offi-
cer, in announcing the purchase.
The facility has a planned initial capacity of 700 million cubic feet
per day, and will produce about five million metric tons of LNG an-
nually. Project construction could begin in 2012, with exports pot-
entially starting in 2015. The project is operated by Apache Canada,
which will own 40 per cent, with Encana and EOG Resources
Canada each owning 30 per cent.
Talisman is also moving to find new markets and better pricing
for its Montney production. In December 2010, it announced a joint
venture with South African chemical giant Sasol Limited, with Sasol
paying $1 billion for 50 per cent of Talisman’s Farrell Creek play. At
the time, the companies said they would also investigate the feas-
ibility of constructing a 46,000-barrel-per-day gas to liquids facility
based on Sasol’s technology that is currently being used in three fa-
cilities around the world. In March 2011, a second joint venture was
announced on Talisman’s Cypress properties.
Sasol’s global general manager, Leon Strauss, says a gas to li-
quids plant makes sense because of what the company views as
“a long-term structural shortfall in the dynamics between prices of
natural gas and crude that makes gas to liquids an even stronger
value proposition.”
With the second joint venture, the two companies are investigat-
ing whether a 96,000-barrel-per-day facility is possible. While the
study is just beginning, Strauss says, “overall we are optimistic
about its outcome.” ■

The technology has also breathed new life into the moribund con-
ventional oil industry, and is expected to slow the long decline in
production that began in 1973 as a number of tight oil plays take off.
The Bakken/Three Forks play in southeastern Saskatchewan is
where the tight oil revolution began in western Canada. In the past
five years, over 2,000 horizontal wells with multi-stage fracture com-
pletions have been drilled into the play, with production reaching
over 65,000 barrels per day in 2011.
“The Bakken pool is now the largest producing oilfield in west-
ern Canada,” Greg Tisdale, chief financial officer of Crescent Point
Energy Corp., told a BMO Capital Markets conference in 2010.
“With an estimated four [billion] or five billion barrels in place, the
Bakken light oil resource play is the largest pool discovery in west-
ern Canada in the last 50 years.”
Crescent Point is the most significant producer in the Bakken, with
32,000 barrels of oil equivalent per day of production and 930 net sec-
tions of land. The company has 3,800 drilling locations in inventory.
But even with a decade of development drilling ahead, Crescent
Point is piloting four waterflood tests in the hopes of capturing more
resource. The first pilot began in 2001, and the results have been
encouraging. Crescent Point estimates it will increase the recovery
factor from the three-well pattern from 19 per cent to 30 per cent.
The company drilled 13 injection wells in 2010 and plans for up to 40
injection wells by the end of 2011.
Tisdale says Crescent Point expects the waterflood scheme will
allow the company to increase recovery by around 307,000 barrels
per well, and that this will transfer into increased economic value for
the company.
“Three wells under primary production would be worth around
$18 million,” he says. “Under waterflood, the value of those wells
would be $24.6 million.
PetroBakken Energy Ltd. is the second-largest producer. In re-
porting the company’s 2010 results in March, president and chief
operating officer Gregg Smith said the company has plenty of de-
velopment drilling ahead as well, with a focus on drilling long bilat-
eral horizontal wells with more than 20 fracture intervals per well.
PetroBakken has drilled 121 bilateral wells into the Bakken since
2009, and plans for another 75 bilaterals into the play in 2011. It has
900 potential targets in its Bakken inventory.
PetroBakken is also advancing enhanced recovery plans, in-
jecting gas rather than water to force more oil out of the rock.
“We did a carbon dioxide injection on a well early in 2010,” said
Smith. “We started a well in February, and injected carbon dioxide over
two days. We wanted to use natural gas but it is more difficult to do, so
we chose carbon dioxide for the test case. The offset wells adjacent to
the injector more than doubled in production and 10 months after the
injection they’re still producing 50 per cent higher than what they were
producing before we did the injection, so we think continuous injection
will have quite a positive impact on the play.”
Smith said the next step is to further develop enhanced oil recov-
ery (EOR) plans using natural gas.
“Using natural gas should look like carbon dioxide without the
corrosion issues,” he explained. “Natural gas is cheaper than car-
bon dioxide, and at the end of the day we will recover most of the
gas back, so it ends up acting as a physical hedge and hopefully the
price will be higher as well.”
PetroBakken plans on spending $20 million on its EOR plans in 2011.
With the Saskatchewan Bakken in the development stage, Crescent
Point is now looking to expand its resource inventory further through
targeting the Alberta Bakken play. The company has accumulated over

one million acres of exploration land in southern Alberta targeting mul-
tiple zones, including the Bakken/Three Forks formations.
Tisdale said to date the company has drilled one well into the play
and has plans to drill 19 wells in 2011.
“It’s early days, but we plan on applying what we learned in the
Bakken and Lower Shaunavon to the play,” he said.
Outside the Bakken, the Cardium in Alberta is the busiest of the new
tight oil plays. There are between 10.5 billion and 12.5 billion barrels
remaining in the Cardium play, and a number of companies believe
the multi-stage fracturing revolution can be used to exploit some of
that resource.
Penn West Exploration (the operating entity of Penn West
Petroleum Ltd.) is the most active player in the Cardium and the
most active oil driller overall across western Canada. It has over
650,000 acres in the Cardium play and has identified over 2,500
drilling locations. The company is drilling monobore wells with hori-
zontal legs averaging 1,000-1,400 metres. Each well has an average
of 17 fracture stages.
In March 2011, Penn West president and chief operating officer
Murray Nunns reported to shareholders during the company’s year-
end conference call that after spending 2010 appraising its various
tight oil plays, the company is ready to start development in earnest
this year. And its major target will be the Cardium.
“We have the appraisal of significant areas of the play done and
that has allowed us to prioritize our 2011 capital spending,” said
Nunns. “The bulk of our efforts will be concentrated in the high-
productivity areas of West Pembina and Willesden Green as well as
some other selected areas along the play trend.”
Nunns said Penn West has eight rigs currently working the
Cardium and has drilled 16 wells so far this year. It plans to drill 80 or
90 wells into the play.
Penn West’s current focus is on reducing the costs of drilling and
completions in the Cardium. Pad drilling is being used as one means to
reduce costs. Penn West estimates that by drilling four horizontals per
pad it can reduce lease construction costs from $600,000 per well to
$250,000. Drilling times are reduced from 18 days to 12 days, and rig-
moving costs are reduced from $200,000 per well to $40,000.
The company is also refining its fracturing fluids to improve reliability
and optimize production. Nunns said they have been testing slickwater
fracs and hydrocarbon based fluids side-by-side in well pairs.
“The slick water fracs are not there yet,” he noted. “Right now
things slightly favour hydrocarbons but that could shift in the next
few months.”
Penn West is also extremely active in another of the emerging tight oil
plays, the Viking play near Dodsland, Sask. The Viking had four billion bar-
rels of oil in place, with only around 12 per cent currently recovered.
At Dodsland, Penn West drilled 52 out of the 121 wells industry
drilled in the Viking play in 2010, reporting initial average produc-
tion of 55 barrels of oil equivalent per day per well. The company
is drilling monobore wells with 660-metre horizontal legs, and
using 18 fracture stages per well. Fracture sizes are 12 tonnes,
compared to 20 tonnes in the Cardium. Total well costs in the
Viking are $1.18 million, and Penn West would like to see that
drop to $1.05 million in the upcoming year.
“We are currently appraising the Viking to the north and west, and
now west into central Alberta,” said Nunns. “It provides solid returns
and significant running room for Penn West.” ■

The bad news?
Public concern about the environmental impacts of fracturing on
groundwater have led to a political firestorm in the province and a
halt to shale gas exploration and development until studies can be
completed on the potential associated environmental effects. The
studies are expected to take up to 30 months, slowing momentum in
what was one of the hottest exploration plays underway in Canada.
By year-end 2010, industry had drilled 29 wells in the Utica play,
with 18 wells receiving fracture treatments. Early results are encour-
aging. Talisman Energy Inc., which has drilled 10 wells in the play
along with partner Questerre Energy Corporation, reported aver-
age production from vertical wells of 600,000 cubic feet per day,
and production from its first horizontal well drilled in 2010 came on
stream at around 10 million cubic feet per day and averaged 5.3
million cubic feet over its first 30 days. Two other horizontals are
still under evaluation. Forest Oil Corporation and partner Junex Inc.
have also reported strong results with two early vertical wells deliv-
ering around one million cubic feet per day of initial production.
Early estimates put the original gas in place in the Utica shale as high
as 116 billion cubic feet per section. Overall, there could be as much as
60 trillion cubic feet of potential recoverable shale gas in Quebec.
In 2009, the Quebec Oil and Gas Association (QOGA) hired consult-
ing firm SECOR Group to look at the economic benefits shale gas de-
velopment could bring to the province. SECOR found if development of
shale gas goes ahead, baseline studies indicate $1 billion to $3 billion
in capital investment per year over the next 15 years.
SECOR examined two scenarios, involving multi-well pad drilling of
150 wells per year and 600 wells per year, with six wells drilled from
each pad. The study calculated the creation of 5,000-19,000 jobs per
year. The study also predicted government revenue would be $1.4 bil-
lion to $5.4 billion per year, depending on the number of wells drilled.
Public worries about air pollution and groundwater contam-
ination, however, have put the potential economic windfall at risk.
Pressure has been building against shale gas exploration since it
began in earnest in 2008.
In late 2010, Talisman and Questerre announced they were delaying
further fieldwork until a government-led hearing was completed on the im-
pacts of development. In March, the results of the hearing were released,
calling for restricted hydraulic fracturing activity until its effects could be
better understood. Industry now waits for the results of planned studies.
QOGA president and former Quebec premier Lucien Bouchard
told a press conference following the announcement that the con-
flict over shale gas development is because the industry failed to do
due diligence in explaining itself to the public. Bouchard said a lack
of expertise in the province that has caused a number of wells to
leak is also to blame for the problem.
“We all forgot that there is absolutely no culture, no experience of
gas and oil development in Quebec—that we were starting afresh,”
he explained. “We all forgot that it was something new. It was a
shock in Quebec because of that.”
Also speaking at the press conference was Jim Fraser, vice-
president of North American shale gas operations for Talisman
Energy Inc. Fraser said that going forward, the industry needs to do

a better job explaining the process involved in drilling and complet-
ing shale gas wells to get the public on board with development.
“We need to educate the people of Quebec to those practices to
earn their trust,” said Fraser.
Fraser said the decision to limit hydraulic fracturing could have an
impact on his company’s operations this year, but it’s too soon to
say what that impact would be.
Bouchard said the Quebec industry would back the government
study on shale gas and help in any way it can to make it run smoothly.
“The government has our support to quickly put in place the meas-
ures required to conduct a thorough study and promote an informed
debate regarding the collective decisions to be made,” he said.
“Association members wish to make it clear that they will take an active
role. Together with all Quebecers, they believe that development of gas
resources is not possible unless it serves the public interest.”
During the study’s duration, some exploration drilling may con-
tinue to help provide the technical information needed. Bouchard
said the information gleaned should also help in advancing the eco-
nomic case for furthering shale gas development.
“The economic value of gas resources is not yet proven, and the
only way to know if Quebec has viable gas resources is through field
testing,” he noted.
Other petroleum industry associations, including the Canadian
Energy Pipeline Association (CEPA), the Canadian Gas Association,
the Canadian Natural Gas Vehicle Alliance, the Canadian
Association of Petroleum Producers, and the Canadian Society for
Unconventional Gas, have launched a public relations campaign to
encourage Canada, both federally and provincially, to make natural
gas, including shale gas, an integral part of the energy mix.
“We are confident, based on experience in other jurisdictions,
that shale gas can be developed safely in Quebec,” CEPA president
Brenda Kenny said in describing the effort, called the Canadian
Natural Gas Initiative.
While the Quebec environment department studies shale gas ex-
ploration, its finance department is continuing to move forward in
laying the fiscal groundwork for the industry. In its 2011-12 budget,
the government laid out its plans for its future royalty structure in
a new report.
“Our action is focused on shale gas. It is now reasonable to believe that
Quebec’s subsoil holds substantial shale gas potential,” said Finance
Minister Raymond Bachand in announcing Quebec’s royalty plans.
The report states that the new royalty regime will come into effect
once the strategic environmental assessment has been completed
and the legal and regulatory framework has been adapted to its
conclusions. This regime includes a commodity price and produc-
tivity component and varies between five and 35 per cent.
The intention of the new system is for total government take, in-
cluding corporate taxes, to be 50 per cent in mature development as
compared to their estimate of 33 per cent under the current system.
It has been modelled on the royalty regimes in Alberta and British
Columbia for conventional production.
In recognition that the Utica shale is not yet mature, the minis-
ter also announced the introduction of a Gas Development Program
modelled on the Net Profit Royalty Program that is used in north-
eastern British Columbia. The progressive royalty rate starts at two
per cent and varies through a four-tiered scale based on the recov-
ery of capital invested and returns achieved. ■

Halifax-based Corridor Resources Inc. reported that its part-
ner Apache Corporation had completed segregated testing of two
intervals in the Frederick Brook formation that had been fractured
with propane at the vertical Green Road G-41 well, located approxi-
mately four kilometres north of the village of Elgin in southern New
Brunswick. The first test interval was flowing natural gas at a sta-
bilized rate of 430,000 cubic feet per day. The second test interval
flowed at a peak rate of 11.7 million cubic feet per day and a final
stabilized rate of three million cubic feet per day.
With an estimated 67 trillion cubic feet in place, it looked like the
province’s shale gas industry was on its way.
But a year later, things don’t look quite so clear.
In December, Corridor announced Apache Canada Ltd. had completed
two follow-up horizontal wells. Strong gas shows were encountered in
the horizontal section of both wells during drilling. Five slickwater fracture
stimulations were completed in each of the wells, including one frac com-
pleted in the highly productive zone of the G-41 well.
Unfortunately, after the plugs were drilled out in both horizontal
wells, negligible gas flows were reported. Corridor said “The pre-
liminary performance of these wells is both unexpected and perplex-
ing,” but cautioned that “it is important to recognize that the evaluation
of the development potential of the Elgin shale gas resource play is
in its early stages.”
One step forward, two steps back. Nova Scotia’s early-stage
shale gas exploration play has experienced a similar up and
down start.
In 2007, Triangle Petroleum Corporation subsidiary Elmworth
Energy Corporation and its partners drilled two vertical wells in the
Windsor Block to test the Horton shale. Both test wells proved suc-
cessful in showing the resource potential of the play. Based on an es-
timated resource of 89 billion to 109 billion cubic feet per section from
Schlumberger Limited’s log analysis, the company reported the project
had the gas in place to drive the company’s exploration program.
That same year Triangle reported that Ryder Scott Company, L.P.,
its independent reserves-evaluation engineering firm, estimated the
resource potential for the Horton Bluff Shale to be 69 trillion cubic
feet of original gas in place.
“The identification of 69 trillion cubic feet of resource potential
by Ryder Scott is a major step in our development of the Horton
Bluff Shale resource in Nova Scotia,” Triangle president Howard
Anderson said. “Although this resource assessment only covers 40
per cent of Triangle’s land block that is delineated by seismic, this is
an extraordinarily large accumulation of natural gas in close proxim-
ity to a premium market.”

In 2009, Elmworth signed a production lease covering 10 years
for its Nova Scotia shale play. Since then, however, activity in the
area has stalled with the crash in gas prices resulting in Triangle fo-
cusing on the Bakken light tight oil play in western Canada.
Despite the setbacks, exploration in East Coast shale plays is ex-
pected to continue in the years ahead.
Corridor already has tight gas production at its McCully field in New
Brunswick. The field contains 138 billion cubic feet of proved-plus-
probable reserves and produces 18 million cubic feet per day from 30
wells in the Hiram Brook tight gas sand reservoir. The Frederick Brook
shale play directly underlies the Hiram Brook tight gas sands.
In December 2009, Corridor signed the partnership deal with
Apache to explore the Frederick Brook. The first part of the joint ven-
ture, completed late last year, called for Apache to spend $25 million to
drill at least two 1,000-metre-long horizontal wells and use multi-stage
hydraulic fracturing technology to complete the wells. This work includ-
ed the successful G-41 well and the two follow-up wells.
Apache now has until June to decide whether it wants to spend
another $100 million over the next two years to earn a 50 per cent
interest in 116,000 gross acres of Corridor-controlled lands in south-
ern New Brunswick. If it decides to move forward, Apache would
drill and test six to eight more wells in three or four areas within the
play by March 31, 2013.
“Though plans are not certain, Phase 2 would probably consist of
three pairs of horizontal wells in three different locations,” says the
company. “Each pair would be one tight gas siltstone well and one
shale gas well. We anticipate these horizontal wells would be at depths
greater than 2,000 metres, have approximately 2,000 metres of hori-
zontal length and we would use 10 to 20 fracture stages per well.”
Full-scale development in New Brunswick would likely mean
drilling of one to two pads a year for up to 30 years. Each well pad
would have eight to 16 horizontals. Water for the massive slickwater
fracs would likely come from the Atlantic Ocean.
Apache isn’t the only large U.S.-based independent target-
ing Maritime shale deposits. Unconventional gas specialist
Southwestern Energy Company, which is focused on the Fayetteville
shale play in Arkansas and the Marcellus play in the northeast-
ern United States, has licences totalling 2.52 million acres in New
Brunswick. The company spent around $11 million in 2010 com-
pleting an airborne magnetic and gradiometer survey and plans on
spending another $14 million this year doing core sampling, shoot-
ing between 1,000 and 1,300 kilometres of 2-D seismic and other
early exploration work before spudding its first well in 2012.
Southwestern Energy’s land is north of the Corridor acreage, in
an area that’s essentially unexplored. It plans on testing both the
tight sandstones currently being produced by Corridor, along with
the Frederick Brook shale.
Junior producer Contact Exploration Inc. currently has light tight
oil production in the Stoney Creek field in New Brunswick. In 2010,
the company drilled two horizontal wells with multi-stage fractures
with one well initially producing 135 barrels a day and the other 60
barrels a day. Contact Exploration plans three to five additional
wells this year, and a total of between 12 and 15 wells in the future.
The company also has an estimated 11 trillion cubic feet of shale
gas resource in place on its New Brunswick lands. Going forward,
Contact Exploration says it may drill vertical wells to test the play, or
find a joint-venture partner. ■

TOGOLDTalisman Energy is pinning its shale gas market strategy on proven gas-to-liquids technology
By Peter McKenzie-Brown
The way he tells the story, “from some work we’d done [with Home
Oil subsidiary Scurry Rainbow Oil Ltd.] in the late 1980s, we origin-
ally thought it was the source rock. A number of us believed that
the Montney formation contained an abundance of hydrocarbons to
deliver, and we set out to prove it up.”
He led the formation of a private company, Rocor Resources Inc.,
with initial funding of $2 million, although during the company’s brief
life it raised an additional $15 million.
“Our mandate was to prove this idea, then to hand over the keys
to a company with deep pockets, as it takes an awful lot of capital
to develop these plays with horizontal wells. To do a job like this and
become a producing company you would probably need $50 million
to $100 million.”
Rocor demonstrated the existence of wet shale gas with vertical
wells only. “As we were drilling, we had a lot of condensate coming
in and killing the well.”
The company’s thinking was strategic in several ways. “We
bought 14 sections of land between two rivers,” says Soares.
“Whoever owned that land could control things when they started
planning facilities. When word got out about what we’d done, land
prices all around us really started to go up—like in any real estate
boom. We were the first in the area drilling for this resource, but ob-
viously people with deeper pockets soon overtook us.”
In October 2008, Rocor sold out for $50 million to Petrobank
Energy and Resources Ltd., which promptly drilled a horizontal well
that produced 8.5 million cubic feet of gas plus 350 barrels of con-
densate per day—“tremendous results,” according to Soares.
WhAT TO dO WITh ShALEY pLAYSAt least part of the significance of Rocor’s efforts was that it illus-
trated the tie between tight gas and shale gas. According to Dave
Russum, AJM Petroleum Consultants’s geoscience vice-president,
the Montney is a case study in a kind of “hybrid” natural gas re-
source—a hydrocarbon formation halfway between gas from tight
sands (the prospect Scurry Rainbow had originally been investigat-
ing) and shale gas pure and simple. In fact, according to Russum,
these prospects are best described as “shaley plays.” They contain
shale and sand in relatively larger and smaller percentages, but

ThE UNCONvENTIONAL “BIg ThREE”tight sand, shale and coal reservoirs
whether they are more like tight sand or shale gas they require frac-
king to yield economic production.
In a real sense, the shaley gas plays are an extension of Canadian
Hunter Exploration Ltd.’s Deep Basin tight gas developments of the 1970s.
Montney occupies one end of the shaley gas spectrum, and partly in-
cludes old-fashioned tight gas. Horn River, which taps the Muskwa shales
in a basin just south of the Northwest Territories and just west of Alberta, is
a picture-perfect shale gas play. According to Russum, it may prove to be
the biggest shale gas play in North America.
Of course, in an environment of rapidly expanding gas supply, the
key issue is what to do with the stuff. In recent months, Talisman
Energy Inc. has placed two major bets on the use of gas-to-liquid
(GTL) technology, which transforms natural gas into a combination
of high-quality liquid fuels and petrochemical feedstock.
gAS-TO-LIqUIdSThis effort began last December, when Talisman announced a billion-
dollar joint venture on its Farrell Creek property in the Montney play
in northeastern British Columbia. In March, the company announced
a similar deal with respect to its Montney-area Cypress A proper-
ties. Talisman’s partner in both ventures is petrochemical giant
Sasol Limited, which honed its expertise in turning coal and nat-
ural gas into liquid fuels during an international oil boycott imposed
upon South Africa during apartheid. The company’s two South
African coal-to-liquids facilities represent the largest and most
profitable assets in Sasol’s portfolio. On behalf of the partnership,
the Calgary-based company will operate the Cypress A and Farrell
Creek projects as integrated development projects.
Sasol and Talisman are investigating the economics of building
North America’s first gas-to-liquids plant. In cautious news release
language, the companies agreed to undertake feasibility studies
“to examine a world-scale gas-to-liquids [GTL] facility in western
Canada, with Talisman having the option to participate as a 50 per cent
partner in the facility. This could provide a strategic alternative to
traditional North American pipeline or LNG [liquefied natural gas]
markets. The GTL process produces premium, clean liquids fuel.
Sasol is leading this study with a front-end engineering design de-
cision likely in the second half of next year.”

Put another way, a decision on whether to proceed with an engin-
eering design for the Canadian project is expected in 2012.
The Talisman/Sasol plant would turn western Canadian gas into
value-added liquid fuels and petrochemical feedstocks. Converting
natural gas into liquid fuels is particularly attractive now, given the
prospect of an extended period of low natural gas prices in a high oil
price environment. This solution could create diesel and other fuels
that are used in automotive transport.
GTL, which will become increasingly significant as crude oil re-
sources are depleted, is operational already in a number of Sasol
plants around the world. In addition, supermajor Royal Dutch
Shell produces diesel from natural gas in a factory in Malaysia.
When finished, its Pearl GTL plant in Qatar will be the world’s lar-
gest GTL facility.
Until recently, GTL only made sense in gas-producing regions
that could not build pipelines to major markets. The reason it has
suddenly become economical in western Canada, of course, is that
despite ample pipeline capacity to North American markets, British
Columbia’s shaley gas projects have created huge supply surpluses
at the end of one of the world’s longest gas pipeline systems.
In a corporate statement, Talisman president and chief execu-
tive officer, John Manzoni, put it like this: “This transaction allows
Talisman and Sasol to unlock additional value in the world-class
Montney shale play and potentially accelerate development of the
resources in the area. The Cypress A assets are very similar to
Farrell Creek and, with our partner, we will now build an integrated
long-term development plan for the area.”
Sasol chief executive Pat Davies added that “this additional ac-
quisition of another high-quality natural gas asset will accelerate our
upstream growth while also potentially advancing Sasol’s already
strong GTL value proposition utilizing our proprietary technology.”
That pretty much sums it up.
NATURE’S gIfT TO ThE WORLdIn a presentation a year ago, the chairman and chief executive of-
ficer of ConocoPhillips, James Mulva, called natural gas “nature’s
gift to the world.” Taking a shot at the unbendable greens—he called
them “hydrocarbon deniers”—Mulva complained that “they support
renewables at any cost and oppose hydrocarbons at any conse-
quence…. They seem not to realize that platitudes are not BTUs.”
Citing the environmental advantages of gas, he argued that indus-
try and government should ensure that the world’s gas supplies are
used to their full potential.
If they do, he argued, by 2050 natural gas will have potentially
helped meet four great energy challenges: achieving U.S. and
world energy supply security; providing consumers with affordable
energy; driving economic prosperity and job creation; and reducing
greenhouse gas emissions. He argued that vast conventional and
unconventional gas resources—more than 38,000 trillion cubic feet
globally, by some estimates—will ensure stable supplies and reduce
the risk of long-term price volatility.
Within that context, much needs to be done to develop supplies
and to develop markets for natural gas. Surely GTL will play an in-
creasingly important role in exploiting nature’s gift. ■

Where to Go?
Some say transportation should be a market grail for natural gas, while others aren’t so sure
By Peter McKenzie-Brown
The problem with conventional wisdom is that it isn’t always true.
Contrarians are often right.
pRICE BULLIt’s worth keeping that truism in mind as we develop the case for build-
ing new natural gas markets in North America. In a recent comment,
author and analyst Peter Tertzakian argued that the rapid decline in drill-
ing for natural gas across North America raises the question of whether
natural gas is likely to continue to be in a serious state of oversupply.
Tertzakian notes that for the first time in 15 years, half of the
United States’ drilling fleet is drilling for oil, compared to less than
20 per cent of the rigs for the last decade. Such a dramatic decline
in drilling almost certainly suggests that production levels will de-
cline, he suggests.
He then moves on to the killer argument: “Let’s say [gas] pro-
duction starts retreating in earnest this year and natural gas prices
rise back to some fictional level like $6 per thousand cubic feet.
Notionally, the [conventional] wisdom goes that producers will dis-
patch more rigs to ramp up production and thus clobber prices
again. There is a problem with this line of thinking: why would pro-
ducers do that when more money is to be made elsewhere?”
He suggests that as long as oil is valued at more than four times
the value of gas (on an energy-equivalency basis), there is little mo-
tivation for the industry to shift toward more gas drilling. The result?
Declining supply and still higher gas prices until a cost-reward re-
balance restores aggressive natural gas drilling.
SUppLY BULLSince Tertzakian is such an unusual voice in the wilderness, the
balance of this article assumes that the conventional wisdom is
true. Gas supplies are likely to continue to be plentiful, and there
will continue to be a need to develop new markets. One of the most
interesting advocates of greater markets is the legendary oilman
T. Boone Pickens, who says he has invested $70 million in de-
veloping and promoting the Pickens Plan.
Now an 83-year-old geologist who received his degree in geology
in 1951, as a young man, the Texas-born Pickens spent a decade
in Calgary. In a broadcast interview, he said he opened an office
in Calgary in 1959 and lived in the province with his family in the
1960s. After moving back to the United States, he made a multi-
billion dollar fortune in exploration and development and, much
more publicly, as a corporate raider. His current passion is promoting
the Pickens Plan.
“For 40 years, the United States has had no energy plan,” he ex-
plained in a recent radio interview. “We’ve just been drifting. Just
drifting means you are just importing more oil from the Middle East,
countries that the state department recommends we not visit.”
Pickens is adamant that the United States should reduce its de-
pendency on overseas oil, and he believes that renewables like wind
and solar energy aren’t viable anymore because of cheap gas.
“Natural gas is the only thing we have that can replace non–
North American foreign oil. We import five million barrels from the
Mideast. That’s the oil I want to replace with gas. If you had eight
million 18-wheelers [in the U.S. trucking fleet fuelled with natural
gas], that would cut OPEC [Organization of the Petroleum Exporting
Countries] imports in half.”
He added, “If the U.S. administration announced that from now
on all new government vehicles would use domestic fuel, that would
be a powerful message to send to the world.
“This is a security issue for me. I don’t want to be dependent on
the enemy for energy,” he said.
Until gas prices cratered, Pickens was a strong advocate of wind
energy, and he was leading an effort to finance a multi-billion dollar
wind farm in the Texas Panhandle. He uses this fact to support his
green credentials.
“Natural gas is 30 per cent cleaner than diesel. We have the
cleaner, cheaper, abundant fuel here, and it will replace the dirty fuel
from the Mideast.”
Pickens is also an advocate of continental fuel switching—in particu-
lar, substituting natural gas for coal in power generation facilities.

For many years, most commentators have believed that the
United States could never become self-sufficient in energy, Pickens
said, but “things have changed. We have so much natural gas—
the U.S. has a 100-year supply, and the Canadians have a lot up in
Horn River, for example, and the Canadians have a lot of oilsands
[oil]. Let’s use that to make North America energy self-sufficient.”
He added, “When people say to me, ‘Hey, Pickens, I don’t like your
plan!’ I say, ‘Fine, what’s your plan? If you don’t have a plan, your
plan is to import more oil from the Middle East.’”
Not many oilmen are as colourful as T. Boone Pickens or as mo-
tivated by worries about enemies in the Middle East. However, there
are a lot of other natural gas supply bulls.
ExxonMobil Corporation, for example, demonstrated its belief by
plunking down US$31 billion for gas-focused XTO Energy Inc. a year
and a half ago. Company vice-president, William Colton, recently
told The New York Times that “if there is any kind of major trend,
we think it’s going to be a shift toward more natural gas.” He added
that “Natural gas is available. It’s the most efficient way to generate
massive power. It’s affordable. We already have gas infrastructure
in place. From a CO2 emissions standpoint, it’s 60 per cent cleaner
than coal, and [the United States has] 100 years of supply.”
AgENCY BULLThe U.S. Energy Information Administration (EIA), whose job it is to
forecast supply and demand based on best-guess current trends,
doesn’t appear to see much of a plan to promote greater use of natural
gas anywhere in the future. According to the early bird version of its
2011 forecast, “non-hydro renewables and natural gas are the fastest-
growing fuels used to generate electricity, but coal remains the dominant
energy source for electricity generation because of continued reliance on
existing coal-fired plants” well into the foreseeable future.
According to the EIA, the agency has revised its methodology
for gas prices “to better reflect a lessening of the influence of
oil prices on natural gas prices, in part because of the increase
in shale gas supply and improvements in natural gas extraction
technologies.”
Of course, as Peter Tertzakian argues, it might be a mug’s game
to discount energy equivalency too deeply when you are calculating
the relative values of oil and gas.
Whatever methodology the organization uses, the EIA does fore-
cast an increase in North America’s natural gas demand, but its es-
timates seem paltry compared to the aggressive development that
Pickens, for example, is promoting.
The agency forecasts a strong near-term increasing demand
because of a “strong recovery in near-term industrial production,
growth in combined heat and power, and relatively low natural gas
prices.” Look farther out into the future, however, and the agency’s
forecasters are more circumspect than the gas supply bulls.
“U.S. natural gas consumption rises 16 per cent from 22.7 trillion cubic
feet in 2009,” the agency intones, “to 26.5 trillion cubic feet in 2035.”
Such a small increase in forecast demand—16 per cent over 25
years—suggests that the EIA’s gas supply bulls aren’t as optimistic
as Pickens; he might complain that they “don’t have a plan.” You
could equally argue that there are contrarians among them. ■

A SUStAinAble FUtUre Effectively marketing Canada’s vast
unconventional gas resources can help
ensure global sustainability
By Peter McKenzie-Brown
According to company spokesman Alan Boras, in 2010 “we re-
placed 250 per cent of our production. We [now] have 14.3 [trillion
cubic feet] of proved reserves.”
Of course, much of the company’s new reserves have come from its
aggressive shale gas development. But consider this: “Coalbed meth-
ane is also an important part of our production—about 10 per cent.”
Encana’s numbers illustrate the remarkable success of the un-
conventional gas narrative. The big kid on the block is shale gas,
but other sources like coalbed methane and tight gas are also im-
portant parts of the mix. Unless market conditions somehow kill the
development of new supply, gas will remain plentiful and affordable
for a long time to come.
This prospect provides Canada’s petroleum sector with a num-
ber of market opportunities. The first is the development of liquefied
natural gas (LNG) capacity. The second is to use the fuel as a cheap
input for oilsands development. The third is to go into shaley forma-
tions in the quest for natural gas liquids (NGL) and other valuable
light liquids. The fourth is for oilsands producers to develop both
gas and NGLs for financial hedging. Let’s look at these in turn.
LNgEven though the federal government has given cabinet approval for
Arctic pipeline development, many people in the oilpatch are skeptical
that development will begin soon. Put another way, such legacy assets
as Canada’s Arctic gas fields look increasingly like white elephants.
Robin Mann, chairman and chief executive officer of AJM
Petroleum Consultants, puts the issues in a complex question.
“Because of the development of shale gas formations l ike
[British Columbia’s] Montney and Horn River and others with
great potential right next to infrastructure and pipelines, and with
our existing conventional gas and our exports to the United States
going down daily, we have more than enough [gas] for our own
[use], so why is it important to build these pipelines? Why are we
worrying about anything north of Alberta and B.C.?”
He adds that the costs of the northern pipeline keep going up.
“Maybe the best way is to develop LNG facilities in the north, but
what will the economics of that kind of project be? Will the price of
[Arctic] LNG justify building facilities up there?”
Bill Gwozd, a vice-president of Ziff Energy Group, is much more
sanguine about Arctic gas. His firm’s model suggests there will be
a North American market for Arctic gas beginning in the 2020s, “so
it’s important to get ready now to activate those pipelines,” which
will take a long time to build and commission.
The need for Arctic gas in North America 15 years from now doesn’t
exclude the prospect of beginning to develop overseas exports now,
however. In fact, three big and successful companies—Apache

Corporation, EOG Resources Inc. and Encana—are betting good
money that they can make a serious buck out of the Kitimat LNG
project. According to Gwozd, the chances of winning that bet are
pretty good. “Worldwide, LNG is maybe 10 per cent of supply.
There’s plenty of room to grow it.”
According to Kitimat LNG Inc.’s founding president Rosemary
Boulton, “The development of shale gas has developed a gas bub-
ble that’s especially big in Canada. [For conventional gas] it’s worse
than anything we’ve seen in a very long time. That makes LNG
development more important now than ever.” She adds that
“shale gas is basically a technology play. The industry has found
ways to get at gas that we knew was there before, but couldn’t
develop. And the better companies are finding ways to produce
more efficiently. Efficiency and technology translate in a fairly linear
way to a decrease in cost.
“These projects are all about location,” she adds. “You really have
to have a supportive community to make them happen. First Nations
and other communities along the pipeline route and around Kitimat
were very supportive of the idea of having this project there.”
Because the company was able to develop this support under her
leadership, both the pipeline and the terminal had received regula-
tory approvals before the new owners acquired the project.
ThE AThABASCA OIL SANdS STORYIn a rapidly evolving industry, companies are finding imagina-
tive ways to develop natural gas plays. One of the most inter-
esting examples is Athabasca Oil Sands Corp., which has been
well known for several years as a wannabe oilsands producer.
Through a series of summertime raids at Alberta land sales, in
2006-07 the company became the single biggest landowner in
the oilsands sector—a position it held until Suncor Energy Inc.
gobbled up Petro-Canada Limited a few years back. But oilsands
development is a long-term proposal, and after farming out some
of its land to PetroChina Company Limited, the company had
cash in the bank but no cash flow in prospect until its first in situ
project comes to life next year.
Asian markets are logical targets for natural gas from western Canada.

So what did the company do? Still holding a very large oilsands
land position, the company acquired more than a million acres in
northwestern Alberta’s gassy Deep Basin.
“This is an excellent way for Athabasca to use its cash until
needed for our oilsands development,” says president and chief
executive officer Sveinung Svarte. “This area offers the potential
for a very short pay-back time and we plan to re-invest that quick
return in the oilsands.”
Athabasca’s exploration strategy is to look for liquids and light oil
in a gas-prone basin. The company will do this by drilling into Deep
Basin formations, where it believes liquid-rich natural gas is likely to
be found and easily developed.
The Athabasca story is almost a reverse image of the breakup
of Encana into pure play companies. According to Svarte, within his
company the synergies of diversifying its land position are great. His
geoscience and drilling teams can work in oilsands or tight sands with
equal dexterity.
More importantly, perhaps, diversification will hedge the com-
pany as its oilsands projects begin coming on stream. If diluent
prices are high and bitumen prices low, having diluent production of
its own will help make that problem right.
Of course, the sector in general uses a lot of natural gas—to sup-
ply heat for production and upgrading operations, to produce hy-
drogen for upgrading and to generate electricity. Companies with
gas production could find themselves well hedged if gas prices rise.
As Svarte puts it, “we expect gas to be almost a free by-product of
our Deep Basin development, so this hedge is well-priced.”
WhATIf?With the help of an Ottawa-based thinktank called whatIf?
Technologies Inc., Alberta’s former assistant deputy minister for oil,
Bob Taylor, thinks a forecasting tool he helped develop could enable
policy-makers to better feel, touch and imagine Canada’s possible
energy futures. According to Taylor, the recent surge in gas supply
reflects a pattern that has been continually recurring in Canada for a
century: “Too much gas; too little price.”
Part of his solution to the dilemma this creates was a computer mod-
el that could deal with supply and demand without factoring in price.
Economists would call that heresy; Taylor calls it “dynamic and robust.”
Using numbers the Canadian Society for Unconventional Gas gener-
ated using the whatIf? model, he added that the potential ranges of re-
coverable resource range from a conservative case of 636 trillion cubic
feet to an optimistic case of about 1,400 trillion cubic feet.
Those are extraordinary numbers, but such energy wealth won’t
be developed without trials.
“My worry is that much of this unconventional gas potential remains
unproved,” Taylor says. “For that reason I recommend joint government-
industry efforts.” For political reasons and because of local worries, he
adds, it “may not be recoverable in places like eastern Quebec and off-
shore British Columbia.” While these are serious concerns, he believes
they can be resolved—“but it will require leadership and action.”
A lot is riding on the outcome. If the technical and environmental
issues are solved, Taylor thinks Canada’s plentiful supplies of un-
conventional gas “can be a contributor to helping the world achieve
nine-billion sustainable lifestyles by 2050.” ■

ASmALLerFOOTPrINTUnconventional resource producers are taking a lead role in improving environmental performance
By Jim Bentein
“Low natural gas prices don’t present a pretty picture for small-
er companies involved in conventional natural gas produc-
tion in the Western Canadian Sedimentary Basin,” says Mike
Dawson, president of the Calgary-based Canadian Society for
Unconventional Gas (CSUG). “But the bigger companies can oper-
ate within this low-price environment because they have the capital
and cash flow to enter the shale gas and tight gas plays. They rec-
ognize that, with these unconventional plays, operations are under
intense scrutiny and only exemplary environmental performance will
sustain their social licence to operate.”
Adopting practices that minimize the impact of their operations
on the environment, on landowners and other stakeholders is a ne-
cessary part of doing business, he says.

Dawson sees natural gas prices remaining low for at least a
couple of years, if not longer. “There are companies that are com-
petitive at today’s prices,” he says. “They use a manufacturing-type
approach and they have thousands of locations to develop.”
The low-price world will likely exist for many years, thanks to the
huge new finds of shale gas and tight gas in North America, he says.
The longer-term solution to the price squeeze is to increase gas de-
mand, but Dawson isn’t optimistic about that occurring anytime soon.
“Natural gas use for compressed natural gas to fuel the transpor-
tation and power plants might be the salvation of the industry,” but
he says that won’t happen quickly, because there is a lack of natural
gas transportation infrastructure in Canada and the United States.
Natural Resources Canada released a report in mid-January titled
Natural Gas Use in the Canadian Transportation Sector: Deployment
Roadmap, in which the federal department said wider use of gas, par-
ticularly by Canada’s trucking fleet and other commercial vehicles,
could reduce greenhouse gas emissions from those sources by 25 per cent
and reduce their fuel costs by as much as 30 per cent.
Gas will also eventually gain more market share in the electricity sec-
tor, where it is used as a fuel source for power plants, Dawson says.
It burns about 50 per cent cleaner than coal, and is responsible for
about half of the power production in the United States and about
15 per cent in Canada. But it will take many years until it starts to replace
phased-out coal-fired power plants in the United States, where gas now
is used for about 21.5 per cent of that country’s power, and in Canada,
where it charges about 15 per cent of the country’s electricity plants.
Gas producers have “shifted to what industry giant Encana
[Corporation] calls resource plays,” says Dawson, which al-
low larger producers to operate in a low-price world. They have
moved to shale gas plays like Horn River and tight gas plays in
the Rockies.
The same change has taken place in the oil sector, where produ-
cers have moved to the oilsands and shale oil plays.
In both cases, it’s the larger firms that dominate—and those
larger firms are able to manage operations so that costs are con-
tained and the environmental footprint is minimized.
In the gas sector, this is done through the use of pad drilling and
multilateral horizontal wells (with a similar approach taken in the oil
shale). The resource can be recovered from four or five sections of
land utilizing only one pad.

This “manufacturing approach” taken by unconventional gas pro-
ducers also allows for better planning of roads, pipelines and other
infrastructure, limiting the total footprint of their operations.
“It means the surface disturbance will be smaller overall,” says
Dawson. “Instead of myriad roads, pipelines and electrical infra-
structure crossing the surface, the facilities are more concentrated.”
These economies of scale are even extended beyond one operator.
“Operators may find there are more synergies, where, perhaps,
two operators might drill from a common pad,” says the CSUG
head. “There are opportunities to pool resources, although this type
of opportunity would not come without a spectrum of liability issues,
including equipment, production, environmental and personnel
considerations.”
And Dawson says concerns about the environmental impact of
hydraulic fracturing, the technology used extensively to unlock shale
gas reserves, are simply not based on fact. Critics, particularly in
the United States, claim the technology threatens to contaminate
groundwater sources.
“We need to be very clear about the groundwater issue,” he says.
“It [concerns about groundwater contamination] is not an issue of
hydraulic fracturing, but, instead, of well construction. Protection
of potable groundwater sources is a priority for everyone, including
industry. Proper wellbore construction will ensure isolation and pro-
tection of “fresh” water aquifers. We’ve been using hydraulic fractur-
ing practices for many years without any impact on groundwater.
We have the technology.”
The potential synergies the CSUG head refers to are well illus-
trated by development in the Horn River Basin of British Columbia, a
huge source of unconventional gas in Canada.
But with opportunity comes challenge—a challenge the industry
has responded to.
Encana and Apache Corporation’s Horn River development pro-
duces 75 million cubic feet of gas equivalent per day, with plans to
reach average net production of 110 million cubic feet per day by
year end. The development of the play in this manner makes this
partnership a poster child for the companies’ smaller footprint
manufacturing approach.
Mark Taylor, Encana’s team leader for Horn River development,
says the company is taking lessons learned from its Cutbank,
Montney, Cadomin, Doig and Horn River resource plays in Canada,
Haynesville in the United States, and others continent-wide and ap-
plying them to each of the developments.
“The footprint differs at our different resource plays,” says Taylor.
“We’ve talked about the gas factory approach or the hub approach.
The knowledge flows to our CBM [coalbed methane] and conven-
tional projects, too. It’s all about using a repetitive process. When
you multiply it across thousands of wells, it takes costs out.”
The company can’t deploy the long horizontal wells it does in Horn River
in its CBM plays, of course, but it can use the same basic approach of drill-
ing multiple wells from one pad. (It can drill up to four wells.)
Encana belongs to the Horn River Basin Producers Group, an or-
ganization representing the 10 developers in the play, who share in-
formation on a regular basis.
“We know we’ll never know everything, so a lot of knowledge-
sharing goes on,” says Taylor.
The company, North America’s largest gas producer, strives for
continuous improvement and to always find ways of cutting costs,
says spokesman Alan Boras, “because the low-cost producer wins.”
At Horn River, the company “draws from a huge reservoir” from
a single pad, with 14-16 wells, says Taylor. “For every acre on the
surface, we access 160 acres of the lease.”
That isn’t possible in some resource plays (in the mountainous
terrain of Colorado, for instance), but the same principles apply.
“The overall philosophy is to minimize the environmental foot-
print,” says Taylor. “When you do that, you have cost-savings
in capital and equipment. The two [reducing the environmental

footprint and reducing costs] are not mutually exclusive. You can do
both at the same time.”
Because up to 16 wells can be drilled from a single pad, there are
also improvements in safety.
“We’ll spend 12 months in one location, so, aside from the capital
efficiencies of that, you’re not hauling equipment on roads and rig-
ging up, so it improves the overall safety of the industry,” he says.
Cost savings have been ongoing.
“We thought we were cutting edge in 2009, when we were drilling four
wells from a single pad,” Taylor says. “Now we’re drilling 16 from a single
pad. We spend less on fracs and have cut our costs by 50 per cent.”
While he doubts further cost savings will be “of that order of magni-
tude,” Taylor thinks annual savings of five to 15 per cent are possible.
The Encana manager, who has been with the company since 1986,
says he and his staff are eager to work on resource plays like Horn River.
“It’s exciting. People want to work on resource plays.”
About 90 per cent of the company’s gas production, which hit 1.4
billion cubic feet daily in 2010, up from 1.32 billion cubic feet a day in
2009, came from resource plays.
The centralized planning approach led to an investment that sub-
stantially reduces water consumption at Horn River. The Debolt
water plant, which taps brackish water for fracking operations, has
cut the use of fresh water there by 95 per cent.
“Two years ago, we were using 100 per cent fresh water,” he says.
That not only cuts water use at the project, but also reduces the
company’s water costs.
These and other environmental improvements will continue to
be made because of the company’s approach to resource play de-
velopment, he says.
Encana executives say it is developing what Jeff Wojahn, executive
vice-president and president, USA division, recently called “long-term
strategic partnerships” with its service providers, something that also
helps it reduce costs, advances its continuous improvement agenda
and limits the environmental footprint of its operations.
The industry’s growing concentration on its environmental and
social performance is vital, according to the industry body the
Canadian Association of Petroleum Producers (CAPP).
David Collyer, head of CAPP, warned gas producers last
November that they face the same scrutiny as oilsands producers.
“Fundamentally, the concerns of those that oppose oilsands de-
velopment are linked to local and regional impacts—the land im-
pact, the water impact, for example. This is equally true for natural
gas,” he said.
”They are linked to climate change and they are linked to the off-
hydrocarbon agenda. It’s as relevant, I think, to natural gas as it is
to other parts of the oil and gas sector. We need, therefore, to re-
spond to that as an industry, as a province and I think, frankly, as a
country, in terms of making sure our perspective on those issues is
well-represented.”
He went on to say that those who believe that “if we fixed oilsands
mining,” the opposition to hydrocarbon development “would just go
away” are misguided, arguing that that opposition is fundamentally
directed at the whole industry.
“We have to perform as an industry,” he said. “We have to con-
tinue to raise the bar on performance and we have to communicate
better…and I think that applies to the natural gas industry as it does
to the oilsands business.” ■

From ExxonMobil Corporation’s US$41-billion purchase of XTO
Energy Inc. on down, it speaks volumes that the energy of the future
is natural gas. The future of natural gas is shale gas; and the future
of shale gas is the technology of multi-stage fracking.
And multi-stage fracking often demands copious amounts of
water. So it’s no surprise either that public concerns about drinking-
water protection are on the rise, especially in regions unfamiliar with
the oil and gas industry and the techniques of multi-stage fracking.
In March, for example, Quebec put all licences and exploration on
hold for 30 months so a full environmental impact study can be con-
ducted. Across the border last summer, the New York state senate
approved a moratorium on new drilling permits in that state’s part of
the Marcellus shale pending further environmental studies to ensure
that fracking chemicals won’t contaminate drinking water.
The potential for aquifer contamination caused by hydraulic frack-
ing is probably the public’s leading concern surrounding shale gas
exploitation, and the industry’s as well. Concerns are understand-
able; it’s all about everyone’s quality of life.
“It can’t be brushed under the carpet,” says Brad Rieb, region
technical manager for Baker Hughes Canada’s pressure pumping
division in Calgary. “The onus of responsibility of environmental
stewardship is co-owned. We tell all our customers what we think
is right, wrong or dangerous. Protection of the public is paramount;
that overrides everything we do.”
Multi-stage hydraulic fracturing indeed often demands massive
volumes of water. In some places, today’s horizontal shale gas wells
routinely employ 15 frac stages per wellbore and each stage needs
2,000-3,000 cubic metres of high-pressure injected fluid. And that’s
growing: with the latest in isolation technologies, teams can now ac-
complish as many as 30 stages per wellbore.
Injected frac fluid is typically greater than 99 per cent water and
sand, with the remaining one per cent selected off a menu that typ-
ically includes friction reducers to speed the mix, corrosion inhibit-
ors, biocides to prevent biological growth from clogging equipment
and fissures, surfactants to keep the sand in suspension, and scale
inhibitors such as hydrochloric acid or ethylene glycol. Small per-
centages yes, but clearly it’s critical that the injected mixture not be
allowed anywhere near aquifers, especially those that are potable.
Industry’s first priority is to maintain isolation of the frac—both from
freshwater aquifers and from expanding outside its intended zone.
Rieb points out that the vast majority of shale gas fracs his company
does—excepting perhaps some in the Bakken shale—are in formations
considerably deeper than freshwater aquifers, so risk of contamination
is close to nil. Secondly, technological advances in drilling and tools
can effectively isolate a fracking operation within its desired zone.
“The science of wellbore construction has never been better than
it is today,” he says. “Drilling the well, the mud quality, cementing
the well, ensuring adequate and robust cement bonds, the testing

of those bonds, the science of understanding what these hydraulic
fracs do in the formation—the science and the knowledge behind it
has never been higher.”
But it’s not just a matter of isolating the well itself. On top of that,
the sophistication of modern microseismic techniques allows an
operator to pinpoint with a high degree of accuracy where the fracs
are and, together with knowledge of the geology, whether they will
grow out of the intended frac zone.
Microseismic doesn’t generate energy in the traditional sense ex-
cept for the initial setup; it only ‘listens’ to the frac. With sensors
downhole or on the surface, operators can ‘hear’ the breaks as they
happen—technology now can identify where the frac is in three di-
mensions: azimuth, length and height; as well as its magnitude and
whether it has stayed open or resealed.
The majority of tight gas fracking operations in western Canada
use fresh water as source water, but that’s changing as water de-
mands increase.
Towns like Kindersley, Sask., are growing averse to selling potable
water for the purpose. Moreover, other regions aren’t so lucky to have
such a volume of fresh supply. As has been common in areas such
as the Barnett shale of Texas, where use of recycled water is rapidly
becoming the norm. To use recycled water for fracking, operators start
with the produced water coming out of the fractured well and either
treat it on site or truck it to a remote treatment facility.

Produced water is a mixture that can be of three different sources:
frac water of varying chemistry, flowback water from previous treat-
ments and actual formation water.
Frac water chemistry can vary immensely across a formation.
“This is what makes the chemistry challenge so interesting,” says
Rieb. “The ratios keep changing. For example, the ratio of produced
water to actual flowback material changes all the time.”
In addition, there are often iron compounds introduced by new stor-
age units, pumping equipment, tubulars, treaters and separators.
“It really is a complex blend of water qualities, types and chemis-
tries,” says Rieb. “We insist on getting representative samples from
all these different sources so we can develop systems that serve a
purpose on this used water.”
Several manufacturers provide chemicals especially designed
for use with recycled waters. For example, Trican Well Service’s
EcoClean products are formulated to be non-toxic, biodegradable
and non-bioaccumulating, protecting the environment and handlers
in case of surface spill.
David Browne, Trican’s corporate director of technology, says
they pass the strict Microtox testing—meaning safe for human con-
sumption—and so would not harm an aquifer even if there were
communication between the product and the water.
“Whichever fluid the producers choose to use, whether our
EcoClean line or any of our fluid products, the risk of aquifer con-
tamination is virtually nil,” he says.
Trican also now offers a friction reducer that permits reuse of pro-
duced water even when it contains high levels of salt.
“It enables use of produced water instead of fresh water,” says
Browne. He is speaking of Trican’s FR-8 and FR-9 salt-tolerant fric-
tion reducers, which have been designed for use in water-based
fracturing fluids and specifically for high-salt brines.
Where not recycled, operators typically separate the water from
any oil, treat the water to reduce scale chemical emulsions, and re-
inject it into waterfloods or deep aquifers.
Where suitable underground injection sites aren’t handy, disposal
can be expensive, as it requires trucking or pipelining. Underground
injection has traditionally been considered the best solution for pro-
duced water disposal—using salt or brackish water disposal wells
to place the water in porous rock thousands of metres below fresh-
water aquifers. In between, layers of impermeable rock ensure no
connection can be made with freshwater formations above.
“ There is an ethical obligation to
protect the public and that is
woven in. it has to be scientifically
based and researched.”— Brad Rieb, Region Technical Manager, Baker Hughes Canada

Underground injection of the produced water is not possible in
every play as suitable injection zones may not be available, so treat-
ment and reuse is becoming the more popular option.
“If we can reduce those costs, reuse that water to complete wells
without damage to the formation, that’s where the economics are,”
says Rieb.
In support of that, several new produced-water treatment tech-
nologies and new applications of existing technologies are under
development. Some of the treated water can be reused as frac water
for certain, but in some regions of the United States it can be sold
as irrigation water or even drinking water. Such recycling or reusing
of produced water can serve to alleviate demands on traditional
sources, offering new resources for drought-stricken or more arid
areas—making produced water a potential resource in its own right.
But shale drilling activity doesn’t always stay in one place long
enough to justify a fixed-treatment facility, and transporting it may
not be cost-effective either. Thus, on-site units are appearing on the
market, particularly in the Barnett shale where regulatory-approved
mobile recycling units are becoming ever more popular.
For example, Fountain Quail Water Management, LLC provides
a unit that recycles 80 per cent of flowback water. On-site distilla-
tion units apply heat to separate out and concentrate the salt water,
which is sent to a disposal well, and the remaining distilled water is
reused for fracking. On-site produced natural gas is used to fire the
distilling units.
Another firm, VWS Oil & Gas, offers different treatments. One util-
izes thermal evaporation and crystallization technology as primary
treatment for both flowback and produced waters. Such zero -liquid
discharge (ZLD) solutions, as they are known, have been demon-
strated in treating waters containing both high and low levels of
total dissolved solids. The company claims effective removal of
several compounds: sodium and calcium chlorides and heavy met-
als. Waste generated is restricted to a solid ‘saltcake,’ which is ap-
proved for most landfill disposals. Its ZLD systems generally recover
over 95 per cent of the effluent.
Other on-site treatments start with free oil removal, which is fol-
lowed up with degasification, softening, filtration and reverse osmo-
sis. The sequence reduces water hardness, metals and suspended
solids. And because they’re designed to operate at a high pH level,
they are also effective for controlling biological, organic and particu-
late fouling, and eliminating system scaling.
As the number of shale gas wells grows exponentially, research con-
tinues into ways of keeping it environmentally sound and more efficient.
A case in point is the challenges inherent in the use of biocides.
Produced water and stored water need to be treated, but with
biocides in them, they can’t be placed down a reservoir or disposed
of in natural areas. If not properly disposed of, they become a haz-
ard to living things. So new strains are being studied.
“The food industry has products that are edible,” says Rieb, “but
you can’t just change things overnight.”
Other research is aimed at finding minimum standards for safe
acceptability in water quality, perhaps additives that will allow water
with higher total dissolved solids content to be used.
But there wil l a lways remain the impor tant underl iner.
“There is an ethical obligation to protect the public and that
is woven in,” says Rieb. “It has to be scientifically based and
researched.” ■

Who is CSUG?
Since its inception in 2002, the Canadian Society for Unconventional Gas (CSUG) has had a significant impact on the evolution of the unconventional gas industry in Canada. With a strong focus on technology transfer between industry, government, public stakeholders and First Nations, CSUG’s major role is to provide this information to enable resource development in an environmentally, socially and economically sensitive manner. In 2010, we recognized that the industry is changing as companies increase their unconventional exploration efforts to regions outside of Western Canada and also to emerging resource plays such as liquids rich natural gas and light tight oil.
While natural gas from unconventional sources continues to play an important role in filling the gap between energy demands and declining conventional gas production the growth of this resource throughout North American has provided an opportunity for energy supply assurance for many decades to come. CSUG representatives have been instrumental in educating the public and industry about unconventional gas and will continue to work collaboratively with a wide cross-section of organizations to ensure the responsible and sustainable development of our unconventional resources.

Adsorption/Adsorbed
Refers to the molecular bonding of a gas to the surface of a
solid. In the case of shale, natural gas is adsorbed or bonded to
the organic material in the shale.
Aquifer
The subsurface layer of rock or unconsolidated material that
allows water to flow within it. Aquifers can act as sources for
groundwater, both usable fresh water and unusable salty water.
Casing
Steel pipe placed in a well and cemented in place to isolate
water, gas and oil from other formations and to maintain hole
stability.
Completion
The activities and methods to prepare a well for production fol-
lowing the drilling of the wellbore. This includes the installation of
equipment for production from a gas well.
Conventional Natural Gas
Conventional natural gas is typically made up of 80-90 per cent meth-
ane and consists of a mixture of hydrocarbon compounds and small
quantities of various non-hydrocarbon substances. Conventional gas
is generally defined as gas that is produced using more traditionally
established drilling and completion methods.
damage (formation damage)
Changes to a reservoir rock that have a negative impact on the ability
of the reservoir to produce gas or liquids; commonly considered to
be a reduction in permeability caused by drilling operations.
desorption/desorbed
Removal of an adsorbed or absorbed substance from its ad-
sorbed state.
disposal Well
A well that injects produced water into a regulated and approved
deep underground formation for disposal.
downstream
The refining, marketing and end-use sector of the oil and gas indus-
try is commonly referred to as the downstream sector.
drilling mud
A mixture of clay, water and other ingredients that is pumped down-
hole through the drill pipe and drill bit that enables the removal of
the drill cuttings from the wellbore and also stabilizes the penetrated
rock formations before casing is installed in the borehole.
fault
A fracture surface in rocks along which movement of rock on one
side has occurred relative to rock on the other side.

?flowback
The flow of fracture fluid back to the wellbore after the treatment
is completed.
formation (geologic)
A rock body distinguishable from other rock bodies and useful
for mapping or description. Formations may be combined into
groups or subdivided into members.
Gas in Place (GiP)
The hypothetical amount of gas contained in a formation or rock
unit. Gas in place always represents a value that is more than
what is economically recoverable and refers to the total resour-
ces that are possible.
horizontal drilling
A drilling procedure in which the wellbore is drilled vertically
to a kickoff depth above the target formation and then angled
through a wide 90-degree arc such that the producing portion of
the well extends horizontally through the target formation.
hydraulic fracturing (aka ‘fracking’)
A method of improving the permeability of a reservoir by pump-
ing fluids such as water, CO2, nitrogen or propane into the
reservoir at sufficient pressure to crack or fracture the rock. The
opening of natural fractures or the creation of artificial fractures
to create pathways by which the hydrocarbons can flow to the
wellbore.
Lithification
The process of converting sediment to rock.
methane
The principal ingredient in natural gas.
microseismic
The methods by which fracturing of the reservoir can be observed
by geophysical techniques to determine where fracturing occurred
within the reservoir.
midstream
The processing, storage and transportation sector of the oil and
gas industry.
multi-stage fracturing
The process of undertaking multiple fracture stimulations in the
reservoir section where parts of the reservoir are isolated and
fractured separately.
Permeability
The ability of the rock to pass fluids or gas through it. The higher
the permeability number, the greater the amount of fluid or gas

that can flow through the rock over a fixed time period. Permeability
is measured in a unit called darcies. Conventional reservoirs may
have permeabilities in the 10s to 100s of millidarcies or occasion-
ally in the darcy range. Unconventional or tight reservoirs usually
have permeabilities in the micro- to nano-darcy range (one-
millionth of a millidarcy).
Porosity
The free space within the fine-grained rock that can store
hydrocarbons.
Produced Water
Water produced from oil and gas wells.
Propping Agents/Proppants
Non-compressible material, usually sand or ceramic beads, that is
added to the fracture fluid and pumped into the open fractures to prop
them open once the fracturing pressures are removed.
reserves
The estimated volume of gas economically recoverable from single or
multiple reservoirs. Reserve estimates are based on strict site-specific
engineering criteria.
reservoir
The rock that contains potentially economic amounts of hydrocarbons.
Shale Gas
Natural gas stored in low-permeability shale formations.
Stimulation
Any of several processes used to enhance reservoir permeability.
Thermogenic gas
Natural gas generated from petroleum or other organic matter in a
high-temperature and high-pressure environment.
unconventional Gas
Unconventional gas sources are generally categorized as tight
sands and carbonates, shale gas or natural gas from coal. The
distinction between unconventional and conventional is be-
coming less clear, but unconventional gas is more dif ficult to
produce. It requires specialized drilling, completion and produc-
tion techniques. The actual composition is usually the same as
conventional natural gas—predominantly methane.
upstream
The exploration, development and production sector of the petrol-
eum industry.
Wellbore
A hole drilled into the earth, usually cased with metal pipe, for the
production of gas or oil.
