WHAT IS COAL BED METHANE? •Coal Bed Methane is natural gas generated during coalification process and stored in coal seams in the adsorbed state on the internal surfaces of coal matrix. •Coal serves as both the source and the reservoir rock for CBM and can hold 5-6 times the amount of gas stored in a conventional sand reservoir of comparable size.

  • WHAT IS COAL BED METHANE?Coal Bed Methane is natural gas generated during coalification process and stored in coal seams in the adsorbed state on the internal surfaces of coal matrix.Coal serves as both the source and the reservoir rock for CBM and can hold 5-6 times the amount of gas stored in a conventional sand reservoir of comparable size.The production of CBM is related to permeability & takes place on depressurization of coal beds through dewatering.

    Ranks 6th in global coal production. About 15% of coal production is from underground mines,24 underground mines classified as Degree III gassy mines. Estimated CBM resource base: 1.5 to 2 trillion cubic meters. 26 CBM blocks awarded. Many under active exploration and some moved into development

  • NATURAL GAS: Projected demand and supplyWORLDINDIA

  • WHY CBM?Most hazardous gas i.e Methane Commercial Energy resource. Solving the worlds energy problem for the coming century.Help in meeting the demand-supply curve for natural gas.Methane consumption (highest heat retaining capacity and lowest atmospheric life-time span (about 10 years)) mitigate the global warming at a much faster rate. Consequently, methane hydrateour future powerhouseadversely affected by global warming, will be saved.methane gas as an additional energy resource rational utilization and preservation of coal deposits, which are both the producer and reservoir of this gas.
