French and Christopher J. Schenk This map was created as part of a worldwide series of geologic maps for the U.S. Geological Survey’s World Energy Project, available on CD-ROM and through the Internet. The goal of the project is to assess the undiscov- ered, technically recoverable oil and gas resources of the world. Geologic provinces were created for ranking pur- poses in the World Petroleum Assessment 2000 (U.S. Geological Survey World Energy Assessment Team, 2000). A modified subset of these provinces are shown on the map, based on new bathymetric data and geologic knowl- edge. Geologic province boundaries are not intended to be taken for country boundaries or exclusive economic zone (EEZ) boundaries. The USGS World Petroleum Assessment 2000 - Description and Results can be found online at: http://pubs.usgs.gov/dds/dds-060. Oil and gas fields are represented by a single geographic point in the center of the field and displays field type (oil or gas) only. The map includes three surface geology datasets, which were modified for display purposes. Additional information regarding the map compilation and data can be found on the CD-ROM for USGS Open-File Report 97-470-L, also available online at: http://pubs.usgs.gov/of/1997/ofr-97-470/OF97-470L/ Several software packages were used to generate this map, including: Environmental Systems Research Institute, Inc. (ESRI) ArcGIS 8.3, ArcInfo, Adobe Photoshop CS, Illustrator CS, and Acrobat 6.0.
