摘要

Deeply buried coals in the Piceance Basin contain more than one-fourth of the in-place coalbed methane resource of the United States. The Gas Research Institute (GRI) developed the 'Deep Coal Seam Project,' a field oriented research and development project. The project objectives are to develop, improve, evaluate and communicate the technology required to commercially produce gas from deeply buried coal seams. The project has conducted research at two sites in the Piceance Basin. At the first project site, the Red Mountain Unit, considerable insight was gained regarding drilling, reservoir testing, core analysis, logging and stimulation of low permeability coal reservoirs. However, reservoir testing at the site indicated that the coal reservoir did not have sufficient permeability to achieve commercial rates. Production testing at the second project site, East Divide Creek Unit, indicated adequate permeability and overpressured conditions. Reservoir modelling suggests that this area could produce at commercial rates, however, it was not possible to fully quantify the productive potential of this area due to the lack of coal core information.
