Coalbed methane is the pure methane gas extracted from coal seams, while shale gas is a mixture of propane and butane only that can be extracted from fine-grained sedimentary rocks: CBM is primarily methane stored within coal seams. Shale gas is natural gas (which is primarily methane) trapped within fine-grained sedimentary rocks like shale. Shale gas is not a mixture of propane and butane only; propane and butane are components of natural gas liquids (NGLs) or liquefied petroleum gas (LPG), which can sometimes be found alongside methane, but the primary component of shale gas is methane. This statement is incorrect.<br \/>\n2. In India, abundant coalbed methane sources exist, but so far no shale gas sources have been found: India has significant CBM reserves and has commercial production of CBM. India also has estimated shale gas reserves in various basins (e.g., Cambay, Krishna-Godavari, Cauvery basins), and exploratory drilling has confirmed the presence of shale gas. While commercial production is not as developed as CBM, sources have indeed been found. This statement is incorrect.<br \/>\n<\/section>\n<section id=\"pyq-key-points\">\n&#8211; Both coalbed methane and shale gas are primarily composed of methane (natural gas).<br \/>\n&#8211; Shale gas is found in shale formations, not just a mixture of propane and butane.<br \/>\n&#8211; India has identified sources of both coalbed methane and shale gas.<br \/>\n<\/section>\n<section id=\"pyq-additional-information\">\nCoalbed methane and shale gas are considered unconventional natural gas sources. Extraction techniques like hydraulic fracturing (fracking) are often used for shale gas and sometimes for CBM, though CBM extraction can also involve dewatering. These sources have gained importance globally as potential energy sources, but their extraction methods also raise environmental concerns.<br \/>\n<\/section>\n","protected":false},"excerpt":{"rendered":"<p>With reference to two non-conventional energy sources called &#8216;coalbed methane&#8217; and &#8216;shale gas&#8217;, consider the following statements : 1.
