INDIA ENERGY OPPORTUNITY
COALBED METHANEA NEW SOURCE OF GAS
Mohit K Banerjee
cbm ( An Alternative Fuel)
Coal Bed Methane (“CBM”) found in coal deposits
CBM is in the coal seam in adsorbed condition and held in place by the pressure of under-ground water
CBM is extracted by drilling down to the coal seam, fracturing, de-watering and allowing the gas to flow
Coal quality compares well with global CBM producing coal fields in terms of gas content and adsorptive capacity

A NUISANCE.. TURNED INTO VALUABLE ENERGY….Presence of Methane in coal has always been considered a mining hazard. In most coal mining operation, vast quantities of methane, a potent green house gas are vented to atmosphere through ventilation system. Production of coal bed methane reduces explosion hazard during subsequent coal mining operation, reduces green house gas emission and provides an alternative source of energy.
Thank you !
