Coalbed methane. Technology status report

OSTI ID:6005364

Coalbed methane research focuses on (1) estimating the extent of the resource with increased accuracy and reliability, (2) estimating the amount of coalbed methane that is recoverable, and (3) providing technically and economically viable means for methane recovery. The goal is to promote extensive private use of the resource as a national energy source. DOE has made significant progress in developing new knowledge, including the following accomplishments: Over 90 well sites have been logged, and over 350 core samples have been taken from these sites for desorption and proximate and ultimate analysis tests to provide insight into gas release mechanisms for various coal ranks. A comprehensive geological assessment was made to estimate the gas-in-place for 16 basins. Twenty production tests were completed to develop guidelines for recovery concepts in different geologic environments. While the project has made significant progress, the development of coalbed methane as a contributing source to the US gas supply has not been widespread. The mixing of unconventional gas with conventional natural gas has been investigated for use by residential, commercial, and industrial customers in space heating, coal drying, and onsite power generation. Recovery concepts must be further developed to quantify risks and to establish the economics of coalbed methane for coal mine operators and other investors. 7 refs., 7 figs., 1 tab.
