National Assessment of Oil and Gas Project - Appalachian Basin Province 067 Total Petroleum Systems

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).The purpose of this map is to define and illustrate the geographic limit and geologic boundaries of the Total Petroleum System as required for the USGS National Assessment of Oil and Gas Project. The boundaries define the combined limits of the petroleum system elements -- source rock, reservoir rock, seal rock, and trap--which are described and defined in the text portions of this publication.
