Coal Bed Methane (CBM) Reservoir Property

Coal Bed Methane (CBM) is methane (CH4) gas produced during formation of coal and is stored within the coal bed – stratified sedimentary deposit consisting predominantly of hydrocarbon derived from plant debris of geological past through a process called coalification– occurring at considerable depth under sediment load pressure. In past, methane gas within coal was considered as hazardous causing so many fire accidents while mining out coal from underground mines as it is a highly combustible and the miners used to adopt so many preventive measures to avoid fire accident for safe mining. In recent past around nineties, a new technology is developed to extract methane gas from coal bed before mining out coal deposit. At the same time having significant heat value methane gas, thus extracted, is utilized as a nonconventional energy resources which is otherwise very much ecofriendly. Thus the new technology played a dual purpose – eliminating chances of fire accident from the hazardous...
