PRESIDENT’S MESSAGE
This month’s letter is starting off on a bit
of a somber note. Our group recently lost
two well known geologists this last
month. Bob Wellborn and Wallace
Reeves. I have known both Bob and Wal-
ly for most of my life and I have enjoyed
the time I was able to spend with them.
Our condolences go out to their families.
They will be greatly missed.
Just a quick note regarding this year’s
WGA fieldtrip. While details are still
coming together, and I don’t want to let
the cat out of the bag just yet, I can tell
you that this year’s fieldtrip is shaping up
to be an exciting one. Please keep your
colanders f lexible and I hope you will
join us this summer. Becky Good and
Anne Marquard are doing an excellent job
heading the trip up this year.

Topic: Using a Portable Mass Spectrometer to Streamline Drilling Procedures
Speaker: Joe Large, Field Operations Manager
Affiliation: Mojo Geological Consulting
Summary: Advances in MWD and LWD tools allow teams to maximize exposure to tar -
get and drill smoother wells. Competition advances are allowing higher recovery percentages.
Pay zone identification within a formation will enable maximum exposure of the wellbore to
the “sweetspot”. Real time identification of porosities, fractures and faults in the well can
help optimize completions and regional modeling. Ratios can be used to infer increases and
decreases in water content, quality of hydrocarbons and fingerprint individual hydrocarbon
sources. Compartmentalization techniques can be used to optimize geosteering and comple-
tion procedures, and “bit generated gases” can be used to infer whether low penetrations rates
are due to damaged bits.
Bio: Joseph Large is Field Operations Manager for Mojo Geological Consulting. Over -
seeing the operation, interpretation and daily reporting of Quadrupole Mass Spectrometers
units on drilling sites in the Powder River Basin. Joe is a 13-year veteran of wellsite geology,

Topic: Prediction and Paleohydraulics
Speaker: Brandon McElroy
Affiliation: UW Dept. of Geology & Geophysics
Summary: Understanding Ear th’s past environments and their sedimentary record
requires quantitative inverse models for sedimentary processes derived from modern
environments and experiments. Within the context of fluvio-deltaic strata, it is currently
possible to reconstruct a wide range of parameters detailing conditions in sediment transport
networks as well as their broader environments. However, existing models have limited
precision largely owing to substantial uncertainty in modern measurements. While it is
possible to identify scales at which particular inverse models are best applied, enhancing
predictive and explanatory power of these models requires better constrained modern
relationships. Despite this rather gloomy picture, there are many questions that can be
appropriately addressed connected to the application of sediment mass conservation.
Specifically, I will address recently developed methods for gleaning information at scales from
basin architecture to morphodynamic scales of bedforms, bars, and channels.
Bio: Dr. McElroy has been Assistant Professor of Sedimentology and Surface Processes in the
University of Wyoming Department of Geology & Geophysics since 2012. He has degrees in
Geoscience from University of Michigan and University of Texas. His research group focuses
on sedimentary processes and their application to interpreting Earth’s geologic history. They
use a suite of field and experimental methods to develop and refine relationships between
fluvio-deltaic strata, their transport systems, and their environmental conditions.

Topic: Energy in Wyoming & the World: Critical Choices & Costs
Speaker: John Hebberger Jr
Affiliation: Retired Geologist
Summary: This talk will explain how our 7.5 billion person global society has developed
over the past 150 years, through its dependence on cheap & abundant energy. It will explore
how the energy mix has changed through time, & where the global growth in energy use will
primarily come from. The talk will emphasize and demonstrate how ALL sources of energy
have multiple and often unrecognized costs, costs that extend far beyond simple monetary
ones.
The talk will also explore the future out to ~2030 and then the end of this century (2100),
looking at the possible mix of energy sources that might be used by our global society to meet
its growing needs. It will explore the range of predictions, both gloomy and optimistic for our
society’s future in terms of its future energy needs. In conclusion it will emphasize how abso-
lutely important it will be for our national and global society to find effective answers to the
question of where future energy needs will be met.
Bio: John is a resident of Jackson, Wyoming, living happily with wife Sue since 2005.
BS/MS Geology, University of Missouri, Columbia, 1974 & 1977. He retired from a nearly 3
decade career with Chevron Corporation in 2005. John filled technical and management/
leadership roles domestically & internationally, and is involved in multiple volunteer efforts
and positions on non-profit boards in Teton County.

Wallace K. Reaves (Wally) passed away on
Tuesday, March 13, 2018. Since the 1960’s,
Wally has been a geologist within the Casper
community. He came to Casper in 1962
working originally for Conoco, left Conoco in
the early 70’s and began consulting for the
rest of his career. For the past 20 years he
consulted primarily for Goolsby, Finley &
Associates.
One of his legacies was picking the top and
base of every coal in the Powder River
Basin. Many of you know him, as he was a
frequent attendee for WGA lunches. He never
missed an event if he could help it. Wally
lived as he desired, at his own home until the
last few days of his life.
In recent years, Wally recreated the 1949
Pontiac convertible in which he and his
beloved wife Geraldine had taken their
honeymoon in 1950. Wally and the yellow top
-down Pontiac were a familiar site around
town and at WOGCC.
Wally served in the U.S. Army during World
War II. Memorial contributions may be made
to the Honor Flight, Inc., Attn: Diane Gresse,
175 S. Tuttle Rd., Springfield, OH 45505.
Wallace K. Reaves, 1928-2018
Robert Edward Wellborn Jr.,
age 88, passed peacefully in
his Casper home with family
by his side on January 19,
2018.
Bob graduated in Geological
Engineering from Kansas
University, where he received the prestigious
Haworth Award in Geology. Shortly after
accepting a position with Chevron in
Shreveport, LA, he was drafted into the army.
During the Korean War, Bob served as an
instructor in the Petroleum Products Analysis
section. After graduate school at Berkeley,
Chevron sent Bob to Grand Junction, CO,
where he met his future wife Jody. Bob
continued to work as a geologist for Chevron,
Burton and Hawks, and Wold Oil and Gas.
Bob was a member of WGA for 53 years. He
and his family were able to join their friends in
the professional community at WGA’s 2017
Christmas party. Bob was a long time member
of AAPG, and published many papers on his
various geological prospects.

Led by gasoline and seasonal demand for
heating fuels, US petroleum demand hit
20.3 million b/d in February. Demand was
up by more than 1 million b/d from
February 2017, nearing record highs not
seen for more than a decade, according to
the American Petroleum Institute.
“The economy and energy demand have
continued to show solid momentum so far in
2018,” said API Chief Economist Dean
Foreman. “With US oil and NGL production
at record levels—and a resilient industry
value chain that has absorbed the growth—
consumers are benefiting from this
momentum and enjoying affordable and
reliable fuels made right here at home.”
The strength in US petroleum demand is
consistent with indicators that the
macroeconomic backdrop has remained
solid. However, crude prices declined in
February after seven consecutive monthly
increases. International crude oil prices fell
by more than domestic ones (5.4% for Brent
vs. 2.3% for WTI) in February. WTI crude
oil prices averaged $62.23/bbl, down 2.3%
from January, while Brent averaged $65.32/
bbl for the month, down 5.4% from January.
At these prices, US supply achieved new
highs for production in February of crude oil
(10.3 million b/d) and natural gas liquids
(4.1 million b/d). US refineries also
processed crude and other feedstocks (16.4
million b/d) at record levels for the month,
which displaced petroleum imports other
than a seasonal winter need for distillate.
In addition, the US rig count climbed to 984
rigs as of Mar. 9 and has averaged 959 rigs
through this year’s first quarter; this
represents an increase of 4% above the
average for fourth-quarter 2017 and should
position US production for continued
growth.
