All layers that fell within the state of Wyoming were downloaded and merged, and this oil_wy layer was created by selecting all cells that contained at least one productive oil well, but no productive gas wells. Purpose: The purpose of the cell map is to display the distribution of oil production in quarter-mile cells in each of the provinces defined for the 1995 U.S. National Oil and Gas Assessments that occurred within the state of Wyoming. Supplemental_Information: 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.

Process_Step: Process_Description: Each downloaded zip file was unzipped and shapefiles were imported into ArcMap. All layers that fell within the state of Wyoming were then merged, and a new layer was created by selecting all cells with an attribute value equal to 1 in the SYMB field, which represented cells that contained at least one productive oil well, but no productive gas wells. Process_Step: Process_Description: The new layer was then reprojected to its current Albers projection.
