The Rock Creek Methane from Multiple Coal Seams Completion Project is a research and development effort to advance the technology for economical production of methane from coal seams. Interference testing of a coalbed methane reservoir in the Warrior Basin near Birmingham, Alabama, gives insight into the unique characteristics of coal seams which influence production techniques and strategies. Permeability anisotropy, scale-dependent permeability and a large porosity-compressibility product were observed, all of which have important implications for well field and stimulation design.
