The benefit of coal bed methane (CBM) is that methane is available in the form of clean fuel and also, taking out methane from coal reduces mining hazards. De-methanization of coal seems prior to mining, increases mine safety and improves productivity. CBM extraction does not affect the physico-chemical properties of coal. Methane recovered from coal mines not only significantly reduces the greenhouse gas emission but also substitutes for fuel. A number of CBM projects earlier worldwide were marginal in techno-economics, being highly capital intensive. However, the improved technology has made CBM projects viable. The amount of methane in a coal deposit depends on the quality and depth of the deposit. For CBM exploitation, water is removed from the coal bed (by pumping), which decreases the pressure on the gas and allows it to detach from the coal and flow up the well. The CBM resources of India are estimated of the order of 0.8-1.5 TCM when compared to 114 TCM of Russia, 32 TCM of China and 12 TCM of USA. In order to produce CBM, it is very essential to de-pressurize the reservoir so that methane de-sorption takes place. For de-watering and depressurization, hydraulic fracturing is essential. For exploitation of CBM pumping is required. Coal bed methane holds the promise of meeting the need of energy from hydrocarbon source, which is considered relatively clean. Expertise available globally including drilling, cementing, well completion, etc., can accelerate the pace of development of CBM/CMM resource in India.
