What does this data set describe?

Title:
Oil and Gas Exploration and Production in the United States Shown as Quarter-Mile Cells
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 United States. 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 initially retrieved from IHS Inc.'s 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 well data. No proprietary data are displayed or included in the cell maps. The data are current through 10/1/2005.

Who produced the data set?

  1. Who are the originators of the data set? (may include formal authors, digital compilers, and editors)

  2. Who also contributed to the data set?

    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.

Why was the data set created?

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).


How was the data set created?

  1. From what previous works were the data drawn?

    PI/Dwights PLUS Well Data on CD-ROM (source 1 of 1)
    Group, IHS Energy , 20051001, PI/Dwights PLUS Well Data on CD-ROM: IHS Energy Group, Denver, Colorado.

    Type_of_Source_Media: CD-ROM
    Source_Contribution: Lat./Long. Points, Final Well Class

  2. How were the data generated, processed, and modified?

    Date: 2006 (process 1 of 1)
    Because of the proprietary nature of the more than 3 million wells in IHS Inc.'s PI/Dwights PLUS Well Data, the area of the United States was divided into cells one quarter mile square and the production information of each well is aggregated in each cell. To accomplish this, oil and gas well data for the United States 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 2005 PI/Dwights PLUS 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.

  3. What similar or related data should the user be aware of?


How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?

    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/>

  2. How accurate are the geographic locations?

    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 IHS, Inc. were assumed to be accurate.

  3. How accurate are the heights or depths?

    Not applicable.

  4. Where are the gaps in the data? What is missing?

    The cells were defined using the well data in the IHS Energy, Inc., PI/Dwights PLUS Well database. The IHS, Inc. database contains over three million 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.

  5. How consistent are the relationships among the observations, including topology?

    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 IHS Inc.'s PI/Dwights PLUS Well Data on CD-ROM. 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 IHS Energy, Inc., PI/Dwights PLUS Well Data were of sufficient accuracy for such a national-scale analysis.
