Consider the following statements comparing Coal Bed Methane and shale gas:

Statement 1 fails because shale gas is not merely a mixture of propane and butane; it is predominantly methane trapped in shale rock.

Statement 2 is wrong because India does hold shale gas prospects in basins such as Cambay and Krishna-Godavari.

Coal bed methane is indeed nearly pure methane adsorbed on coal seams, but that is only one part of the first claim.

Both unconventional gases are extracted differently, coal bed methane by dewatering seams and shale gas by hydraulic fracturing.

Since both statements carry factual errors, neither can be accepted as true.

Commercial coal bed methane production in India began from the Raniganj field in West Bengal.
