Dataset Identification:
- Cell maps for each oil and gas assessment unit were created by the USGS as a method for illustrating the degree of exploration, type of production, and distribution of production in an assessment unit or province. Each cell represents a quarter-mile square of the land surface, and the cells are coded to represent whether the wells included within the cell are predominantly oil-producing, gas-producing, both oil and gas-producing, dry, or the type of production of the wells located within the cell is unknown. The well information was initially retrieved from the IHS Energy Group, PI/Dwights PLUS Well Data on CD-ROM, which is a proprietary, commercial database containing information for most oil and gas wells in the U.S. Cells were developed as a graphic solution to overcome the problem of displaying proprietary PI/Dwights PLUS Well Data. No proprietary data are displayed or included in the cell maps. The data from PI/Dwights PLUS Well Data are current as of April 2001.

- evaluation Method Description A visual comparison was made using a sampling of cell locations and cell attributes with well locations and attributes. In particular, the values of latitude and longitude for the wells in PI/Dwights PLUS Well Data were assumed to be accurate.
- evaluation Method Description The cells were defined using the 2001 well data in the IHS Energy Group, PI/Dwights PLUS. The PI/Dwights PLUS Well Data contains over two million, nine hundred thousand wells for the U.S., which, although not a complete tabulation of all U.S. wells, is the most complete well database available for the United States.

- measure Description The accuracy of the cells, as created by the Arc Macro Language (AML) program of L.R.H. Biewick, S. Weiler and C.C. Skinner, depends upon the accuracy of the oil and gas well information in the 2001 version of the IHS Energy Group, PI/Dwights PLUS Well Data. For the National Assessment of Oil and Gas Project, the assumption was made that the data in PI/Dwights PLUS were of sufficient accuracy for such a national-scale analysis.
