Search for oil and gas in the Idaho-Wyoming-Utah salient of the overthrust belt. Report of investigations No. 21

Technical Report ·
OSTI ID:6646992

The portion of the overthrust belt located in northeastern Utah, western Wyoming and southeastern Idaho is considered by the oil and gas industry to be the hottest new oil and gas province in the continental United States. The Cordilleran fold and thrust belt extends from northern Alaska to southern Mexico. Very significant oil and gas reserves were identified in the Canadian thrust belt as early as 1913. However, until the Pineview success in 1975, most geologists felt that the Utah-Wyoming-Idaho salient probably retained very little oil and gas because of its long and complicated history of deformation, uplift, and erosion. Most did agree that sufficient thicknesses of sediments and the required facies for petroleum generation and migration did exist. Modern refinements of seismic exploration techniques have helped unravel the complex geology, and have led to the enormous successes that now characterize the area. This report catalogs the development of geologic knowledge of the area, describes its general geology and petroleum exploration history, profiles the important new oil and gas fields, and discusses some of the obstacles and problems faced by industry in developing this significant new oil and gas province.
