Paper presented at the SPE Unconventional Resources Conference, April 1–3, 2014
Paper Number: SPE-169006-MS
... Abstract Because today's oil and gas industry recognizes the value of coalbed methane (CBM) resources, CBM exploration and development activities, once uniquely North American, are now under way on a global scale. Many publications address technically recoverable resources (TRR) of CBM in small...

... ). It is expected that CBM will contribute significantly to future natural gas supply. Currently, it is contributing nearly 10% of the U.S. gas needs. WHAT IS COALBED METHANE? Coalbed methane (CBM) is a natural byproduct of the coalification process, which converts organic matter like wood, and peat to coal...

Paper Number: SPE-114994-MS
... ABSTRACT A number of laboratory studies on coalbed methane (CBM) have provided data for the relative permeability of coal to gas and water, which are needed to analyze CBM reservoirs, particularly in numerical simulation. The relative permeability curves of coal to gas and water are determined...
