The Total Petroleum System is used in the National Assessment Project and incorporates the Assessment Unit, which is the fundamental geologic unit used for the assessment of undiscovered oil and gas resources. The Total Petroleum System is shown here as a geographic boundary defined and mapped by the geologist responsible for the province and incorporates not only the set of known or postulated oil and (or) gas accumulations, but also the geologic interpretation of the essential elements and processes within the petroleum system that relate to source, generation, migration, accumulation, and trapping of the discovered and undiscovered petroleum resource(s).

This is a coverage of surface and Federal mineral ownership in the Powder River Basin area, Montana and Wyoming. This coverage is the combination of several ARC/INFO coverages and MOSS format files that were collected from the BLM, reformatted as needed, modified, and/or created by the USGS from hard copy BLM 1:100,000-scale surface and mineral management status maps. The Powder River Basin has the largest in-place coal resources of any field in the contiguous U.S. (Keystone, 1997), and produces over one-fourth of the Nation's total coal production (The Mining Record, 1997). In the Powder River Basin, very little of the surface is Federal land, yet almost all of the coal is Federally owned.
