Description:

Abstract:

Cell maps for each oil and gas play were created by the USGS as a method for illustrating the degree of exploration, type of production, and distribution of production in a play or province. 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 dry. The well information was initially retrieved from the Petroleum Information (PI) 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 from WHCS were current as of December 1990 when the cell maps were created in 1994.

Purpose:

The purpose of the cell map is to display the exploration maturity, type of production, and distribution of production in quarter-mile cells in each of the oil and gas plays and each of the provinces defined for the 1995 U.S. National Oil and Gas Assessment.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

A sampling of cell locations and cell attributes were visually compared to a hard-copy plot of wells to identify errors.

Logical_Consistency_Report:

The accuracy of the cells, as created by the FORTRAN program of D.H. Root and R.F. Mast, depends wholly upon the accuracy of the oil and gas well information in the version of the PI 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.

Completeness_Report:

The cells were defined using the well data in the 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 data for each province in the U.S. was run through a FORTRAN program written by D.H. Root (ret.) and R.F. Mast (ret.). This program converted the WHCS data into latitude-longitude points that represent the center-points of quarter-mile 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 in the .cls files from the NOGA 95 Spatial Data Disk (DDS 35) were reformatted into Arc/Info Generate format (ASCII) files. They were then imported into ArcInfo coverages using the GENERATE command. Region/province/play numbers and names were appended to the file using lookup information acquired from tables on the NOGA 95 Tabular Information Disk (DDS36). Finally, production status from the original .cls file were joined to the coverages.
