MAP OF ASSESSED COALBED-GAS RESOURCES IN THE UNITED STATES, 2014 By U.S. Geological Survey National Assessment of Oil and Gas Resources Team, and Laura R.H. Biewick, compiler 2014 U.S. Geological Survey Digital Data Series 69-II 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 plate included in this report 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. Comprehensive geologic studies, supporting data, and reports on the methodology used in assessing undiscovered oil and gas resources in the United States are available at the USGS Central Energy Resources Science Center website: http://energy.usgs.gov/OilGas/AssessmentsData/NationalOilGasAssessment.aspx.
