This e-symposium will look at:
The Mississippian-Devonian Bakken Petroleum System of the Williston Basin is characterized by low-porosity and permeability reservoirs, organic-rich source rocks, and regional hydrocarbon charge. The unconventional play is the current focus of exploration and development activity by many operators. Previous workers have described significant Bakken source rock potential and estimates of oil generated from the petroleum system range from 10 to 400 billion barrels. The USGS (2008) mean technologically recoverable resource estimates for the Bakken Formation are 3.65 billion barrels of oil, 1.85 trillion cubic ft of associated/dissolved natural gas, and 148 million barrels of natural gas liquids.
The Bakken petroleum system is thought to have created a continuous type of accumulation in the deeper parts of the Williston Basin (Nordeng, 2009). A continuous accumulation is a hydrocarbon accumulation that has some or all of the following characteristics: pervasive hydrocarbon charge throughout a large area; no well-defined, oil- or gas-water contact; diffuse boundaries; commonly is abnormally pressured; large in-place resource volume, but low recovery factor; little water production; geologically controlled “sweet spots”; reservoirs commonly in close proximity to mature source rocks; reservoirs have very low matrix permeabilities; and water occurs up dip from hydrocarbons. The Bakken petroleum system meets all these characteristics.
Many of the reservoirs in the Bakken petroleum system have low permeability. Productive areas or “sweet spots” are localized areas of improved reservoir permeability through natural fracturing or development of matrix permeability, or combination of both.
This course is designed for geologists,
geophysicists, engineers, and support technicians who are interested in
the Bakken Petroleum system.
Each e-symposium consists of one-hour live e-symposium, along with material for one full day of independent study. The live portion will be followed by a full day of independent study (not a live event). You will be able to email responses to the readings, along with your study question answers for CEU credit (if you sign up for the extended package).
A., Sonnenberg is a Professor and holds the Charles Boettcher
Distinguished Chair in Petroleum Geology at the Colorado School of
Mines. He specializes in unconventional reservoirs, sequence
stratigraphy, tectonic influence on sedimentation, and petroleum
geology. A native of Billings, Montana, Sonnenberg received BS and MS
degrees in geology from Texas A&M University and a Ph.D. degree in
geology from the Colorado School of Mines. He has over twenty-five years
experience in the industry. Steve has served as President of several
organizations including the American Association of Petroleum
Geologists, Rocky Mountain Association of Geologists, and Colorado
Scientific Society. He also served on the Colorado Oil and Gas
Conservation Commission from 1997-2003 and was the Chair of the
Commission from 1999-2003. He is the recipient of the Young Alumnus
Award, Outstanding Alumnus Award, and Mines Medal from the Colorado
School of Mines, Distinguished Achievement Medal from Texas A&M
University, distinguished service awards from AAPG and RMAG, and
honorary membership awards from AAPG, RMAG and the Colorado Scientific
Since its founding in 1917, the American Association of Petroleum Geologists has been a pillar of the worldwide scientific community. The original purpose of AAPG, to foster scientific research, to advance the science of geology, to promote technology, and to inspire high professional conduct, still guides the Association today.
AAPG provides publications, conferences, and educational opportunities to geoscientists and disseminates the most current geological information available to the general public.
As the world's premier professional association for explorationists, AAPG is about the science of petroleum geology.
It's also about the people.
AAPG's membership is made up of more than 40,000 members in 129 countries in the upstream energy industry who collaborate – and compete – to provide the means for humankind to thrive.
AAPG provides the network of communications that allow those professionals to succeed.
We invite you to see who we are, what we are about and to contact us for membership information or details about the many services we provide.
