Abstract:
The USGS Central Region Energy Team assessed the oil and gas resources of the United States. Cell maps for each oil and gas production area were created by the USGS as a method for illustrating the degree of exploration, type of production, and distribution of production in a play. Each cell represents a one-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, or dry. The well information was initially retrieved from the Petroleum Information Well History Control System (WHCS), 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 WHCS data. No proprietary data are displayed or included in the cell maps. The data used to generate the cells are from WHCS and are current as of December, 1990.
Purpose:
The purpose of the cell map is to display the exploration maturity, type of production, and distribution of production in one-quarter mile cells for each of the oil and gas plays defined in the 1995 U.S. National Oil and Gas Assessment.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
The accuracy of the cells, as created by the FORTRAN program of D.H. Root and R.F. Mast, depends on the accuracy of the oil and gas well information in the version of the Petroleum Information System (PI) Well History Control System (WHCS) database. For the national scale of the 1995 Oil and Gas Assessment, the assumption was made that the data in WHCS were of sufficient accuracy for such a national-scale analysis.
Logical_Consistency_Report:
A sampling of cell locations and cell attributes were visually compared to a hard-copy plot of wells to identify errors.
Completeness_Report:
The cells were defined using the well data in the Petroleum Information System (PI) WHCS database. The WHCS database contains over two 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.
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. In particular, the values of latitude and longitude for the wells in WHCS were assumed to be accurate.

Process_Step:
Process_Description:
Oil and gas well information for each petroleum province in the U.S. was analyzed with a FORTRAN program written by D.H. Root (ret.) and R.F. Mast (ret.). This program converted the PI WHCS data into latitude-longitude points that represent the center-points of one-mile square cells. The cells were then assigned an attribute based on the type of production of the wells located within the cell. The latitude-longitude center points were converted to an Arc/INFO coverage using the GENERATE command.
