The data release encapsulates geospatial data in support of the regional scale study, Coal Geology and Assessment of Coal Resources and Reserves in the Little Snake River coal field and Red Desert assessment area, Greater Green River Basin, Wyoming. The assessment area covers about 2,300 square miles of the Eastern portion of the 15,400 square mile Greater Green River Basin in Southwestern Wyoming. This release includes geospatial data for the study area boundary, depth to coal, thickness of coal, outcrops and reliability. These data were compiled from numerous sources, the primary one being a database of point data that resides in a separate data release.

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...

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...
