In addition to conventional gas, India has estimated coalbed methane (CBM) resources between of 1.4 tern and 2.6 tern, mainly in the east in the area of the coal resources. Just 0.05 bcm of CBM have been produced in 2008/09, but it is planned to expand production to 2.7 bcm by 2015 (Srivastava, 2010). The Damodar basin in West Bengal and the Cambay basin in Gujarat are, according to the state-owned Oil and Natural Gas Corporation of India (ONGC, 2010), promising formations for shale gas. In November 2010, the US and Indian governments announced that the US Geological Survey will help India to assess its shale gas reserves.
