To extract the gas, a steel-encased hole is drilled into the coal seam 100 to 1,500 metres (330 to 4,920 ft) below ground. As the pressure within the coal seam declines due to natural production or the pumping of water from the coalbed, both gas and produced water come to the surface through tubing. Then the gas … See more Coalbed methane (CBM or coal-bed methane), coalbed gas, coal seam gas (CSG ), or coal-mine methane (CMM) is a form of natural gas extracted from coal beds. In recent decades it has become an important source of … See more Coalbed methane grew out of venting methane from coal seams. Some coal beds have long been known to be "gassy," and as a safety measure, boreholes were drilled into the seams from the surface, and the methane allowed to vent before mining.
