Paper presented at the SPE Eastern Regional Meeting, August 17–19, 2011
Paper Number: SPE-149441-MS
... Abstract Over the past decade, production from unconventional reservoirs such as coalbed methane has increased dramatically. The focal driving force for this growth in coalbed methane production was the development and promulgation of reservoir engineering and completion technology. There have...

... accounts for 10% of the total recoverable natural gas reserves in the U.S. (Nelson 1999). Coalbed methane (CBM) production also accounted for 10% of the total U.S. natural gas production in 2002 (Leach 2002). Total worldwide CBM in-place reserves estimates are between 3500 Tcf and 9500 Tcf (Olsen et al...

... 75083-3836 U.S.A., fax 01-972-952-9435. Abstract In the enhanced coalbed methane production (ECBM) option involving injection of CO2 in a coal-gas reservoir, the injected CO2 induces incremental swelling of the coal matrix. This is believed to result in a significant reduction in coal permeability, and...
