Exploration in the Williston Basin started with the discovery of gas in the Upper Cretaceous Eagle Sandstone on the Cedar Creek Anticline in southeastern Montana in the earliest 1900's. Hydrocarbons have been produced from reservoirs of Cambrian, Ordovician (Red River), Silurian, Devonian (Pre-Bakken-Post-Prairie Salt, Pre-Prairie Middle Devonian and Silurian, Mississipian (Madison), Pennsylvanian, and Triassic ages.
