This paper examines the source rocks, reservoir rocks,
tectonics and timing of hydrocarbon migration from the
hingeline and foreland areas of northwestern North America.
Beginning with southwestern Canada and terminating within
the Central Utah Thrust Belt, we will attempt to demonstrate
that large accumulations of hydrocarbons are yet to be
discovered with the largest potential reservoirs in
Mississippian carbonates of the Central Utah Thrust Belt
(CUTB).
Southwestern Canada: When mostly Devonian age oil migrated in late Cretaceous from carbonates
and other source rocks of the hingeline of southwestern Canada, there was only one anticline in the
area of the future thrust belt. We name it proto-Turner Valley, where at least two billion barrels of oil
accumulated. Most of the oil continued to migrate up-dip and to the northeast. Perhaps channeled at
least in part by the Peace River Arch, migration ended at an unconformity/pinch-out trap of
Cretaceous shales on Cretaceous sands and Mississippian carbonates which were in nonconforming
contact with Precambrian granite of the Canadian Shield. As source rocks continued to mature during
later Cretaceous and early Tertiary, the thrust belt simultaneously developed. Condensate and natural
gas migrated, filling about 40 major anticlines. Later uplift and erosion breached portions of the giant
stratigraphic trap to the east in the Athabasca-Cold Lake area which contained upwards of 2.5 trillion
barrels of oil. Mining began in 1967. Today about two million barrels of oil per day are extracted and
refined.
Western Wyoming, eastern Idaho and northwestern Utah: The Permian Phosphoria Formation
yielded vast amounts of oil and some gas from a backarc basin along the continental margin. These
hydrocarbons migrated eastward, probably during late Triassic or Jurassic, through Permo-Penn
Tensleep-Weber and equivalent sandstones. During that time frame anticlines were absent and no
hydrocarbons were deposited in the future thrust belt trend. Anticlines formed much later, probably
during late Cretaceous and early Tertiary. There were, however, many subtle structures (like protoLost Soldier-Wertz) and stratigraphic traps (in the Big Horn Basin), some very extensive, in the
foreland to the east in Tensleep-Weber equivalent sandstones. These traps had most likely formed
along structural anomalies created above junctions of differential Precambrian litho-provinces during
early North American plate convergence with the Farallon (Pacific) plate. The largest of these early
foreland structures was the proto-LaBarge anticline. During Laramide tectonics, the positions of many
of these early, pre-Laramide anomalies were reactivated. The results were complex, tight, often
wrench-related smaller volume folds. Hydrocarbons were sometimes lost during this process as
determined in recent studies of the Lost Soldier area of central Wyoming. In addition, during Laramide
tectonics large anticlines formed that had not been at the earlier locations of antecedent, oil-filled
earlier structures. These are not productive.
By the time anticlines formed in the western Wyoming-Eastern Idaho-Northern Utah thrust belt,
hydrocarbon migration from Paleozoic source rocks of the hingeline had ceased. Sub-thrust
Cretaceous rocks were sufficiently charged with hydrocarbons in a limited area directly associated
with the Tertiary Fossil Basin of southwestern Wyoming. This is where organic rich Cretaceous shales
were buried deeply enough to yield oil and gas. These hydrocarbons migrated upward through
conduits created by or associated with thrust faults (or in some cases by direct contact with reservoir
rocks) to charge about a dozen major anticlines. The producing traps were limited only to the
Absaroka Thrust system. Other adjacent thrust-fault systems were not hydrocarbon charged. In
addition, all thrusted anticlinal trends north of the Fossil Basin area (with a few minor exceptions)
appear to have insufficient subthrust Cretaceous source rock or insufficient burial depth to generate
oil and gas.
Central Utah Thrust Belt (CUTB): Carboniferous age shales and marlstones in western Utah and
possibly eastern Nevada were the source rocks for oil and gas. These hydrocarbons migrated
easterly, up-dip. The proto-Covenant anticline appears to have been charged with oil and gas, prior to
thrusting, in the trend that would later become the Pavant-Canyon Range-to Salina-Gunnison fault
system. The aforementioned is the primary CUTB area of interest as defined by Schelling, et al., in
the 2007 UGA guidebook. Oil, but not gas, migrated after thrusting from the original, proto-Covenant
accumulation, into Navajo Sandstone which was involved in a back-thrusted anticline of the Salina
thrust system. Wolverine Gas and Oil discovered this accumulation, named Covenant, in 2004.
Providence field was discovered later along the same trend producing Carboniferous aged oil and gas
from Navajo Sandstone. These hydrocarbons had migrated from a local source area and may not be
a commercial deposit.
Are there other Navajo fields? Can we assume that no additional, commercial oil and gas
accumulated after Sevier age thrusting given that over two dozen dry Navajo Sandstone test wells (on
seismically defined anticlines) were drilled following the Covenant discovery? Furthermore, can we
assume that no other pre-Sevier, proto-Covenant-like anticlines existed that have accumulations of oil
and gas in Mississippian, or older rocks? Not necessarily. Oil and gas may have accumulated in the
Mississippian and older carbonates before and after Sevier tectonics but didn't continue to migrate
upward into Navajo Sandstone reservoirs. No recent wells since the Covenant field discovery have
been drilled to Mississippian carbonates in Schelling's study area. Furthermore, only three wells, the
most recent drilled 35 years ago, encountered Mississippian-age rocks in the exploration arena. The
structures containing these Mississippian carbonates were included as part of foreland-vergent
detachments of the Pavant thrust system and were encountered further east than their original
depositional position.
Therefore, the stratigraphy and hydrocarbon potential of Mississippian age rocks in the primary CUTB
area of interest, and elsewhere on trend, remain a big unknown. A number of very large anticlines
beckon.

Attention all UGA golfers, friends of UGA golfers, and supporters of the UGA...
We have a reserved a tee time for our ANNUAL UGA/SPE/SME SCHOLARSHIP GOLF
TOURNAMENT!
Wingpointe Golf Course, 8:00am Friday, September 11, 2015, shotgun start as usual. Fun for all!!
Terry Massoth
UGA Golf Chair
We Need a President!
Your association needs you to step up and run for president. There seems to be a
misconception that there is “someone else” who is more qualified or has more time than you –
it’s not true! Sooner or later we all need to take a few turns serving our Association. The
President slot it still open and time is growing short. We could use more candidates in the other
positions too – please search your soul and see if you are ready to take your turn, then contact
the election committee chair.
Please note: We are trying hard to remove the conception that officers need to be from
the SLC area; in reality you can easily fulfill all functions of most positions from
anywhere in the state. Not being able to attend Monday luncheon meetings is NOT a
good excuse to not run. Board meetings can be held evenings or you can participate via
conference call or skype. Only the Program Chair and Treasurer need to be present at
Monday luncheons. You just need to care about the UGA.
Nominations are open until July 15. Candidates will be announced in the August newsletter.
Elections will be in September and early October. New officers take over on November 1. All
positions are a one-year term except President-elect, which is a three-year term.
President-elect – A three-year commitment, the President-elect recommends to the Board the
region or topic for the annual UGA publication and field conference and assigns editors to carry
out the task. Note that the constitution does NOT require a formal publication and multi-day trip
each year. Several of us think that it may be time for the UGA to scale back a bit – for
example, simply run a one-day trip and only produce an informal road log some years (less
time and expense, allowing more members to participate) – this would be your choice. As
President you will guide management of the Association and run meetings. As PastPresident you will continue as a member of the Governing Board, offer sage advice to new
officers, and chair the Nomination Committee.
Program Chair – You will search out and arrange speakers for our regular monthly luncheon
meetings, prepare newsletter announcements, coordinate the meeting venue, set up and run
audio-visual equipment, and introduce speakers.
Secretary – You will handle most correspondence for the Governing Board, record and file
minutes of Board meetings, maintain the membership database, and publish the membership
directory.
Treasurer – You will oversee the Association’s financial resources, keep the accounts current,
track income and expenses, and prepare a monthly financial report for the Governing Board.
You will prepare and present an accurate end-of-year report (ends September 30) and present
a summary of the Association’s financial status and health to the membership at the October
Annual Meeting. You will provide records to a professional accountant and assure that annual
taxes are properly prepared and filed. You, or a volunteer under your supervision, will arrange
for catering of monthly meetings.
To nominate yourself or a buddy, please contact Grant Willis before July 15 –
