Before we get started, remember….

….never upset a Backhoe Operator.


...and above all remember, never ever …

…..upset a Backhoe.


Within recent years several new

technologies have come along

which truly deliver on the promise

of:

Enhanced Personal Safety,

Increased Profitability, and

Reduced Operating Costs.


Game changing technology: Horizontal Drilling

Horizontal drilling was a real game changer, opening up new and old

reserves previously thought unrecoverable and are now major

producers.

Horizontal drilling helped companies be safer, more profitable and

reduce operating costs.


Multi-Stage Fracturing of horizontal formations is a real game

changer, enabling companies to produce more energy through the

same wellsite.

Multi-Stage Fracturing helped companies be safer, more profitable

and reduce operating costs.

Game changing technology: Multi-Stage Fracturing


By drilling several wells on the same pad site companies can reduce

distress on surface roads, reduce operator travel, reduce

construction costs, and greatly reduce Rig relocation costs.

Multi-Well Pad Sites help companies be safer, more profitable and

reduce operating costs.

Game changing technology: Multi-Well Pad Sites


Game changing technology: The Wireless Wellhead

The Wireless Wellhead is a game changing technology that enables

Producers and Operators to bring on wells faster at less cost and at less

risk to personnel. Well performance data starts streaming during flow-

back and throughout the life of the well giving Reservoir Specialists the

tools to produce more.

The Wireless Wellhead makes life safer, increases profitability, and

reduces costs to deploy and maintain remote assets.


•Wire is expensive to purchase

•Wire is expensive to install

•Wire gets stolen

•Wire gets dug through

•Wire can be unsafe

•Wire needs protection

Wire has it’s challenges


•Wire takes up room

•Wire gets sabotaged

•Wire is restrictive

•Wire requires maintenance

•Wire can kill

Wire has it’s challenges


Wire costs have doubled and doubled again….


Ripped from the headlines!

Wire sometimes disappears


Wire is yummy….


Qualified Electricians can be hard to find….

Current Method – Trenching and Backfill

• Flammable, hazardous gases and fluids are

buried in same trench just inches away from a

potential source of ignition.

• More Labor Intensive

• More Materials Required

• Scheduling Issues

• Project Delays

• Frequent Cost Overruns

• Heightened Safety Risks


Oil and Water Tanks

Separator

200-250 feet of

trenching,

metal conduit,

wire, seal-offs,

labor and time.

100-200 feet of trenching, metal conduit,

wire, seal-offs, labor and time.

Wired Installation Costs per wellsite Costs

Engineering and Documentation $250

Administrative and Procurement $250

Materials (conduit, j-boxes, fittings, wire, barriers, seal-offs, labeling) $2,500

Installation (trenching, pulling conduit and wire, labeling, labor) $2,500

Total cost of wiring installation per wellsite $5,500

Deduct transmitter cost differential $4,500

Total savings of the wireless wellhead $1,000

Potential Future Wired Costs per wellsite Costs

Replacement of bad, compromised or stolen conduit and wire $1,500

Reclamation of conduit and wire $500

Increased safety, reduced risk, less surface use, environmentally green priceless

Total Wireless Savings:

$1,000 to $2,500 per site.



When ALL true installed costs are included in a cost evaluation:

TRUE Wireless is the generally the lowest cost option.

Low Battery Warning No YesTheft Risks High, theft of solar panels, wire and batteries are at an all time

historical high with no end in sight.Virtually none.

Field Instrument Diagnostics from SCADA Host

No Yes

Operational Risks due to Adverse Weather

Moderate, gray days will deplete batteries NONE, no solar power systems

Work Over RIG Issues High, Possible damage to solar panel, instrumentation, conduit & wiring

Low, Easy removal of instrumentation

Haul Truck Issues None NoneCost Escalation Risk due to Inflation

High, as metal prices and labor rates rise, so will installation costs

Low, relatively inflation proof

Safety Risks Moderate, more installation time on site has intrinsic dangers and risks

Low, relatively little time spent on site

Land Use Impact Moderate, long installation time creates land use conflict Low, fast installation

Surface Owner Risks Low, no buried conduit Low, no buried conduit

Real World Wireless-EconomicsAdditional Considerations...............


• Typical multi-well pad

Wireless Wellhead Communications


• Wireless field sensors at

well report to base radio:

1. Casing pressures,

2. Tubing pressures and

3. Braden pressures

4. Plunger arrivals



• Wireless field

sensors at separator

and vapor recovery

unit report to base

radio

1. Temperature

2. Level

3. Pressure



• Wireless field sensors on oil

and water tanks report to base

radio:

1. Water tank levels

2. Oil tank levels



• All field devices wirelessly

send data to the base radio

antenna located at the site

rtu.



• Field data is transmitted to

the site rtu



• The well site rtu sends all

field data up to the antenna

located atop the tower.



• Long-haul radio sends all

field data from the well

site rtu to far away field

or corporate offices



• All field data is then forwarded

on to corporate offices for data

processing, engineering,

accounting, management,

operations, etc.



22 Well Pad in Piceance Basin

with zero trenching to wellhead


Single panel manages all pad instruments. Notice how few number of

wires landed near zero instrument commissioning.


Original pilot well drilled to test the formation and is

networked wirelessly with the wells below, without line of sight.


Non-Line of site install to four tanks measuring interface, level and

temperature.


Once the rig slides to drill the next well, the frac head is instrumented

allowing measurement of gas during flow back while providing tubing and

casing pressures to the drilling engineers for added value far beyond the

norm. The pad is Div 1 until the rig leaves the site .


Drill Here Frac Here Flow-Back Here Produce Here

Wireless makes SIMOPS safer, more productive, and more economical.

SIMOP: Simultaneous Operations


Once completed the arrival sensor is installed.


When all wells are completed, the pad is left nice and clean having had

zero trenching to the wellheads. Later, when a well gets a work over,

there is high probability the instrumentation will not be damaged –

improving the cost of ownership for this producer.


• Rapid deployment for new and retrofit applications

• Plunger Arrival sensor, Pressure Sensor for Tubing, Casing

and Braden Head

• Temperature, sand erosion and valve positioning can be

added
