<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 Pennsylvania. 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. Data were retrieved from the Pennsylvania Internet Record Imaging System (PA*IRIS). 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).</purpose>
<current>The data were retrieved in 2006</current>

<attraccr>The cell locations and cell attributes were visually compared to the hard-copy map: Mast, R.F., Root, D.H., Williams, L.P., Beeman, W.R., and Barnett, D.L., 1998, Areas of historical oil and gas exploration and production in the conterminous United States: U.S. Geological Survey Oil and Gas Investigations Map I-2582, 1 sheet; http://energy.cr.usgs.gov/oilgas/noga/oilgasmap.htm and http://pubs.usgs.gov/of/1995/ofr-95-0075-c/</attraccr>

<logic>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 locatable oil and gas wells data from the Pennsylvania Geological Survey. For the USGS map compilation showing Areas of Historical Oil and Gas Exploration and Production in the United States, the assumption was made that the data from the Pennsylvania Internet Record Imaging System (PA*IRIS) were of sufficient accuracy for such a national-scale analysis.</logic>
<complete>The cells were defined using 2006 well data in the Pennsylvania Internet Record Imaging System (PA*IRIS). No proprietary data are displayed or included in the cell maps.</complete>

<procdesc>The statewide database was brought into ArcMap as an event theme and then saved as a point feature class in a personal geodatabase.

<procdesc>The Pennsylvania oil and gas well data 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 well data into quarter-mile cells and latitude-longitude points that represent the center-points of the quarter-mile cells. The cells were then assigned an attribute based on the type of production of the wells located within the cell.</procdesc>
