<abstract>A cells polygon feature class was created by the U. S. Geological Survey (USGS) to illustrate the degree of exploration, type of production, and distribution of production in the State of Indiana. 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, or the type of production of the wells located within the cell is unknown or dry. The well information was acquired from the Indiana Geological Survey, Petroleum Database Management System (PDMS). Using the table viewer at http://igs.indiana.edu/pdms/getdata.cfm, oil and gas well events and locations tables were downloaded for the entire state of Indiana. Cells were developed as a graphic solution to overcome the problem of displaying proprietary well data. No proprietary data are displayed or included in the cell maps. The data are current as of 2006.</abstract>
<purpose>This Geographic Information System (GIS) dataset was created to display present and past oil and gas production in the United States, as well as the location and intensity of exploratory drilling outside producing areas. This map compilation is an updated version of the USGS map that was published by Mast and others (1998). This product differs from other oil and gas maps of the United States in the following ways: (1) the oil and gas data sources are current as of 2004 through 2006, (2) base cartographic reference data are included, using the USGS National Map and a World Shaded Relief map service from the ESRI geography network, (3) an internet map service is available online, (4) Alaska oil and gas data are included.
To construct this map, digital data were used from more than 3 million wells in IHS Inc.'s PI/Dwights PLUS Well Data on CD-ROM, current through 10/1/2005. In some areas, the PI/Dwights data tend not to be complete, particularly for pre-1920 production. IHS data was supplemented with state wells databases for Indiana, Pennsylvania, Kentucky, Illinois, and Ohio, (current as of 2004 to 2006).
<current>The Indiana wells data set was retrieved in January, 2006</current>
