The goal of the project is to assess the undiscovered, technically recoverable oil and gas resources of the world. For data management purposes, the world is divided into eight regions based on political boundaries, and corresponding approximately to the economic regions of the world as defined by be U.S. Department of State. The region is divided into geologic provinces. Each province has a set of geologic characteristics that distinguish it from surrounding provinces. These characteristics may include the predominant lithologies, the age of the strata and the structural style.
Some provinces contain multiple genetically-related basins.
Offshore province boundaries are defined by the 2000 meter contour. Some stratigraphic units are combined to simplify the map and to ensure consistency across the region. All rocks are colored by age. Sedimentary and metamorphic rocks are not differentiated whereas igneous rocks and their types are indicated by patterns superimposed on the appropriate age color.
