National Assessment of Oil and Gas Project - Powder River Basin Province (033) Regions of Oil and Gas Potential

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: January 27, 2026 | Last Modified: 2021-05-20T00:00:00Z
Regions of high or low potential for oil and gas resources in the Powder River Basin generally indicate where continuous oil and gas resources are more or less likely to be found. These regions are based on several kinds of structural features that were plotted using a Geographic Information System (GIS) and drawn on a map by an assessment geologist. Structural features include faults, anticlines, synclines, and lineaments which may: 1) enhance secondary reservoir permeability and 2) provide migration pathways in unconventional rocks.
