  • About Coal Seam Gas New Site Lock the Gate

    Coal seam gas (CSG) mining is a risky, invasive form of unconventional gas mining. Coal seam gas extraction usually involves tens of thousands of gas wells, with roads, pipelines, compressor stations, wastewater dams, and other infrastructure. A CSG project can spread across hundreds of thousands of hectares of land.

    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 energy in United States, Canada, Australia, and other countries. The term refers to methane adsorbed into the solid matrix of the coal. It is called 'sweet gas' because of its lack of hydrogen sulfide. The presence of this gas is well known from its occurrence

During the formation of coal, large quantities of gas are generated and stored within the coal on internal surfaces. Because coal has a large internal surface area, it can store up to seven times as much gas as a conventional natural gas reservoir of equal rock volume.Coal seam gas is held in place by water pressure. To extract it, wells are drilled through the coal seams and the water
