Coal Bed Methane (CBM), also known as coal seam gas, is a form of natural gas that is extracted from coal beds or coal seams. It is primarily composed of methane, with small amounts of other gases such as carbon dioxide and nitrogen. The gas is adsorbed onto the surface of coal particles within the coal seam, making it different from conventional natural gas deposits found in underground reservoirs.
The extraction of Coal Bed Methane involves drilling wells into the coal seams to release the gas trapped within them. This process requires the removal of water that naturally occurs in the coal seam, which can help increase the methane content of the gas being extracted. CBM extraction has gained significant attention as a viable energy source due to its abundance in coal-rich regions and its potential to provide cleaner burning fuel compared to other fossil fuels.
Coal bed methane extraction dates back to ancient times, though the modern systematic extraction began in the late 20th century as a response to the increasing energy demands worldwide.
