Elk Point Group
From Wikipedia, the free encyclopedia
The Elk Point Group is a stratigraphic unit of Early to Middle Devonian age in the Western Canada and Williston sedimentary basins. It underlies a large area that extends from the southern boundary of the Northwest Territories in Canada to North Dakota in the United States. It has been subdivided into numerous formations,[4] number of which host major petroleum and natural gas reservoirs.[5]
