Abstract

This report presents a digital map of coalbed-gas 

resource assessments in the United States as part of the U.S. 

Geological Survey’s (USGS) National Assessment of Oil and 

Gas Project. Using a geology-based assessment 

methodology, the USGS quantitatively estimated potential 

volumes of undiscovered, technically recoverable natural 

gas resources within coalbed-gas assessment units (AUs). 

This is the third digital map product in a series of USGS 

unconventional oil and gas resource maps. The map can be 

printed in hardcopy form or downloaded in a Geographic 

Information System (GIS) data package, including an ArcGIS 

ArcMap document (.mxd), geodatabase (.gdb), and published 

map file (.pmf). In addition, the publication access table 

contains hyperlinks to current USGS coalbed-gas assessment 

publications and Web pages.

Access to Report

This entire publication is available online at the USGS Web site:

Access to Assessment Results

Comprehensive geologic studies, supporting data, and reports on the methodology 

used in assessing undiscovered oil and gas resources in the United States are
