The USGS assessment and methodology reports cited within this software release require extensive processing using computational methods and modeling. The most demanding aspects of the modeling were performed using publicly available software: SGeMS and GSLIB (See the 'Related External Resources' section on this webpage to learn more about this software). This publication releases the FORTRAN source code of 15 supplementary computer programs that are required to perform the more specific aspects of the modeling. Upon downloading a program, the user needs to use a FORTRAN compiler for generating the executable code. The tasks performed by these FORTRAN programs are: • blankgridsis, for blanking of several realizations...
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(NCRDS), Anadarko Land Corporation (Anadarko), Wyoming Oil and Gas Conservation Commission (WOGCC), and previously unpublished data in USGS files.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...
ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact
