Definition - What does Bakken Formation mean?
Bakken Formation is a shale rock formation that was deposited in late Devonian early Mississippian age and is formed by three layers of Shale namely, upper layer, middle dolomite layer and lower shale layer. These layers are organic rich sources and hold hydrocarbons produced from microbial decomposition of organic matter. The dolomite layer of shale is also called tight sandstone layer or tight sand. This shale formation is located in West Northern region of Dakota and Eastern Montana as well as parts of Saskatchewan and Manitoba in the Williston Basin.
Petropedia explains Bakken Formation
Bakken Formation, also known as Bakken Shale Formation is considered to be one of the largest oil and natural gas deposits in the United States in the past 40 years. This formation has moved the state of Dakota to position two in the highest crude oil producing states because of the large amount of oil and gas produced from this region. The state is only second to Texas which is the highest crude oil producing state in the United States. Some of the oil operators working in this formation are: Continental Resources, EOG Resources, Whiting Petroleum Corp, Hess Corp, Kodiak Oil and Gas and many more are there.
