Overview
A worldwide series of digitally compiled maps include petroleum geology, geologic provinces, and oil and gas fields was released by the US Geological Survey World Energy Project, now called the World Petroleum Assessment. The goal of the project was to "assess the undiscovered, technically recoverable oil and gas resources of the world and report these results by the year 2000."
From USGS--"The world was divided into eight energy regions corresponding approximately to the economic regions of the world as defined by the U.S. Department of State. Each region was then further divided into geologic provinces on the basis of natural geologic entities and may include a dominant structural element or a number of contiguous elements. Some provinces contain multiple genetically related basins. Geologic province boundaries were delineated using data from UNESCO geologic maps, and other tectonic and geographic data. Offshore province boundaries were defined by the 2000 meter bathymetric contour from the UNESCO geologic maps (see References). Each province was assigned a unique number; the first digit is the region number. An attempt was made to number the provinces in geographical groups; onshore, offshore, and combined on and offshore."
Source materials for the geologic maps ranged from 1:2,000,000 to 1:10,000,000 in scale depending on region. Oil and gas field markers represent field centerpoints published with permission from Petroconsultants International Data Corp., 1996 database. Political boundaries and cartographic representations on this map were taken, with permission, from ESRI's ArcWorld 1:3 million digital coverage.
Data Layers
Data are available as shapefiles, ArcInfo coverages, ArcInfo export files (.e00), ArcInfo generate files (with .csv attribute data). Data are also available in both Albers Conical Equal Area and in Geographic Coordinates. Some layers are not available in all formats or projections. The following data layers are available:
- Geologic Age and Geologic Contacts
- USGS Defined Geological Provinces
- Geologic Contacts, Faults and Bathymetric Contours (line)
- Political Boundaries (1:3m data from ESRI ArcWorld)
- Outline of USGS World Oil and Gas Assessment Region
- Index Map of the World (in Robison projection)
