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. The purpose of the cell map is to display the exploration maturity, type of production, and distribution of production in quarter-mile cells in each of the oil and gas assessment units and each of the provinces defined for the National Assessment of Oil and Gas Project. 2005 publication date Complete None planned -98. -83. 35. 29. -96.771929 -84.847208 33.905939 29.944017 Central Energy Resources Team Keyword Thesaurus National Assessment of Oil and Gas USGS World Energy Region 5 Energy Resources Oil Natural Gas Resource Assessment Earth Science Natural Resources U.S. Geological Survey USGS Geology Assessment Unit Dyman, T.S.

ARC/INFO version 8.2 https://energy.cr.usgs.gov/oilgas/noga/oilgasmap.htm and https 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. 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. 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. IHS Energy Group 2001 Denver, Colorado IHS Energy Group Digital 200104 200104 PI/Dwights PLUS Well Data on CD-ROM Lat./Long. Points, Final Well Class Wells that have a reported occurrence of the Cotton Valley Group or of the Travis Peak or Hosston Formations were retrieved from PI/Dwights Plus, a trademark of Petroleum Information/Dwights, d.b.a. IHS Energy Group. Data are current as of 4/1/01. The boundaries of the assessment units were determined by Dyman and Condon, and were drawn on (a) the basis of the distribution of Cotton Valley or Travis Peak and Hosston wells, (b) the type of hydrocarbon produced (oil or gas), and (c) on lithologic characteristics of the Cotton Valley sandstones. The hypothetical assessment units were defined to include areas where potential source or reservoir rocks occur, but where no oil or gas has been produced. 2005 Oil and gas well data for each assessment unit were run through an Arc Macro Language (AML) program written by L.R.H. Biewick, S. Weiler, and C.C. Skinner. This program aggregated and converted the 2001 PI/Dwights PLUS Well Data into quarter-mile cells and latitude-longitude points that represent the center-points of the quarter-mile cells. The assessment unit cells were then assigned an attribute based on the type of production of the wells located within the cell. Region, province, total petroleum system, and assessment unit codes and names were appended to the file using lookup information acquired from tables created for the National Assessment of Oil and Gas Project. 2005 Vector Complete chain Entity point GT-polygon composed of chains Point 0.000001 0.000001 Decimal degrees North American Datum of 1983 Geodetic Reference System 80 6378137.0 298.257222 au"assessunitnum"cg.pat or au"assessunitnum"cg.dbf Polygon Attribute Table.
