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 Illinois. 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 Illinois State Geological Survey (ISGS) oil and gas wells database. 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.
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).

Native_Data_Set_Environment: Microsoft Windows XP Version 5.1 (Build 2600) Service Pack 2; ESRI ArcCatalog 9.1.0.722
Data_Set_Credit: To aggregate well data into quarter-mile cells, 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.
Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report: 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/
Logical_Consistency_Report: 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 GIS data layer from the Illinois State 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 Illinois State Geological Survey were of sufficient accuracy for such a national-scale analysis.
Completeness_Report: The cells were defined using the 2006 well data in the Illinois State Geological Survey (ISGS) oil and gas wells GIS data set. The information is based on well data supplied to the Illinois State Geological Survey (ISGS) and is not field verified. The ISGS does not guarantee the validity, accuracy, and completeness of this data.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report: A visual comparison was made using a sampling of cell locations and cell attributes with well locations and attributes. The horizontal positional accuracy of the Illinois oil and gas well locations is based on well data supplied to the Illinois State Geological Survey (ISGS) and is not field verified. The ISGS does not guarantee the validity, accuracy, and completeness of this data.

Process_Description: The Illinois State Geological Survey (ISGS) created a comma-delimited file that they made available for download at their ftp site (03/16/06). There are 192,310 records of oil and gas wells in this file (isgshead.txt). 3/20/06 the file was exported from Microsoft Excel to a .csv file that was imported into ArcMap and saved as a shapefile. The shapefile was converted to a coverage and 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 2006 Illinois oil and gas well data into quarter-mile cells and latitude-longitude points that represent the center-points of the quarter-mile cells. The Illinois cells were then assigned an attribute based on the type of production of the wells located within the cell.
