Geographic Scope

The Significant Oil and Gas Fields of the United States Database covers all producing provinces (basins) in the United States except the Appalachian Basin and the Cincinnati Arch. To facilitate data research, testing, and use, the database is divided into eight geographic regions: Gulf Coast Cenozoic, Gulf Coast Mesozoic, Gulf of Mexico, Illinois-Michigan, Midcontinent, Pacific (including Alaska), Permian, and Rocky Mountain. A map of these eight regions tied to the AAPG-CSD geological provinces appears below.
