Geospatial Data for Coal Beds in the Little Snake River coal field and Red Desert area, Greater Green River Basin, Wyoming
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 U.S. Geological Survey conducted an assessment of coal resources and reserves in the Little Snake River coal field and Red Desert area of the Greater Green River Basin in Southwest Wyoming. A comprehensive database was compiled to support this assessment that includes data points for drill-holes and measured sections. Associated with these resources are lithology descriptors, (focusing on coal beds of varying depth) as well as coal quality data. Sources of data includes the USGS National Coal Resources Data System (NCRDS), Anadarko Land Corporation (Anadarko), Wyoming Oil and Gas Conservation Commission (WOGCC), and previously unpublished data in USGS files. The primary table describes the sample location and...
New Source Rock Data for the Lewis Shale from the eastern part of the Southwestern Wyoming Province, Wyoming and Colorado
In 2021 the United States Geological Survey (USGS) sampled the lower part of the Upper Cretaceous Lewis Shale in the eastern part of the Southwestern Wyoming Province to better characterize its petroleum source rock potential for an upcoming resource assessment. Ninety-five samples from 24 wells were collected from well cuttings of the lower part of the Lewis Shale stored at the U.S. Geological Survey Core Research Center in Lakewood, Colorado. The selected wells are located near the shallow margins of the basin to obtain samples that were not subjected to the effects of deep burial and subsequent organic carbon loss due to thermal maturation as described by Daly and Edman (1987) (fig, 1). The sample intervals were...
