The Assessment Unit is the fundamental unit used in the National Assessment Project for the assessment of undiscovered oil and gas resources. The Assessment Unit is defined within the context of the higher-level Total Petroleum System. The Assessment Unit is shown herein as a geographic boundary interpreted, defined, and mapped by the geologist responsible for the province and incorporates a set of known or postulated oil and (or) gas accumulations sharing similar geologic, geographic, and temporal properties within the Total Petroleum System, such as source rock, timing, migration pathways, trapping mechanism, and hydrocarbon type. The Assessment Unit boundary is defined geologically as the limits of the geologic...

Cell maps for each oil and gas assessment unit were created by the USGS as a method for illustrating the degree of exploration, type of production, and distribution of production in an assessment unit 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, dry, or the type of production of the wells located within the cell is unknown. The well information was initially retrieved from the IHS Energy Group, PI/Dwights PLUS Well Data on CD-ROM, which is a proprietary, commercial database containing information for most oil and gas wells in the...

The hydrogen index (HI) is a parameter obtained from Rock-Eval data which reflects general hydrocarbon generation and maturation trends in petroleum systems. In the Mississippian Barnett Shale, the hydrogen index was used to map general boundaries between regions of oil and gas generation within the extents of the formation. Hydrogen index values were obtained via Rock-Eval analyses of Barnett Shale core samples. In this system, HI values greater than 100 represent primarily oil generation and HI values less than 100 represent primarily gas generation. Secondary gas generation is indicated by HI values less than 50. In addition, the 100 HI line was utilized to establish part of the assessment unit (AU) boundaries...

The maturation contours show vitrinite reflectance trends and ranges for petroleum system horizons within the Southwestern Wyoming Province. The horizons are the base of the Niobrara Formation, the top of the Frontier Formation, the base of the Mesaverde Formation, the top of the Mesaverde Formation/base of the Lewis Formation, and the top of the Lewis Formation. The ranges of vitrinite reflectance shown for the Niobrara horizons are 0.6, 0.8-1.3, and 1.3. The ranges for the top of the Frontier are less than 0.6, less than 0.8, 0.6-0.8, 0.8-1.3, and greater than 1.3. The ranges for the base of the Mesaverde are less than 0.6, 0.6-0.8, 0.8-1.1, 1.1-2.0, greater than 1.1, greater than 1.3, 2.0-2.2, greater than 2.0,...

Coalbed Methane wells are provided as a method for analysis and illustration of the degree of exploration, type of production, and distribution of production in an assessment unit or province. Each point represents a well location and is symbolized as producing oil, gas, both oil and gas, or other (dry or unknown) using the status code in the attribute table. Data were provided by the Wyoming State Oil and Gas Conservation Commission. See supplemental information section for limitations and assumptions about data.
