The basin is a geologic structural basin but not a topographic depression; it is transected by the Missouri River ...
The Bakken Formation (/ ˈ b ɑː k ən / BAH-kən) is a rock unit from the Late Devonian to Early Mississippian age occupying about 200,000 square miles (520,000 km 2) of the subsurface of the Williston Basin, underlying parts of Montana, North Dakota, Saskatchewan and Manitoba.
The geology of North Dakota includes thick sequences oil and coal bearing sedimentary rocks formed in shallow seas in the Paleozoic and Mesozoic, as well as terrestrial deposits from the Cenozoic on top of ancient Precambrian crystalline basement rocks. The state has extensive oil and gas, sand and gravel, coal, groundwater and other natural ...
The Bakken Shale - a vast formation underlying parts of North Dakota, Montana, and South Dakota - has taken the U.S. by storm. Counties in North Dakota that were previously as quiet as a graveyard ...
The angular unconformity between the Deadwood Formation and the underlying Precambrian metamorphic rocks near Rapid City, South Dakota.. At the type locality in the Black Hills of South Dakota and in many other areas, the Deadwood Formation rests unconformably on Precambrian metamorphic rocks that were exposed to a long period of erosion prior to the deposition of the formation.
Devon said Monday it had agreed to acquire the Williston Basin business of Houston-based, private equity-sponsored Grayson Mill Energy in a $5 billion transaction consisting of $3.25 billion of ...
Oil produced from the Three Forks Formation in the Williston Basin of North Dakota and south-eastern Saskatchewan is often included in production statistics with the overlying Bakken Formation. For instance, the Three Forks and Bakken were combined in estimates of potential production released by the United States Geological Survey on April 30 ...
The Parshall Oil Field is an oil field producing from the Bakken Formation and Three Forks Formation near the town of Parshall, in Mountrail County, North Dakota. The field is in the Williston Basin. The field was discovered in 2006 by Michael Johnson and sold the play to EOG Resources, which drilled, and now operates, most of the wells. [1]
