Description:
The report is a compilation of quality assured data on gas content and coalbed reservoir properties for 11 major coal bearing regions in the U.S. The primary source of these data is the U.S. Bureau of Mines (BOM) gas content measurements program conducted during the 1970s and 1980s. In order to enhance the utility of the BOM data, an evaluation was conducted to compile and quality assure the original data, and to adjust the data as needed to improve quality and representativeness. The report was compiled to provide access to these improved data at the basin level. Under this effort, the original raw data records for the core samples were provided by the BOM. The raw data were digitized to allow a computer to accurately and consistantly perform routine quality assurance checks, consistantly determine lost gas and total gas content for each sample, and examine various corrections to the data. In addition, desorption constants for each coal sample were determined from time series desorption curves generated from the original data. Additional data presented include the results of equilibrium adsorption isotherm tests performed by the U.S. Department of Energy in 1983 for approximately 100 of the BOM coal samples. These results give important, basin level information on the capacity of various coalbeds to store and release methane.
