Similarly, if India commercially exploits shale deposits, it could meet its ever-increasing energy demand, decrease oil and gas imports, and improve the balance of payments.has gained significant political advantage. Recent negotiations between the Secretary of the Organisation of the Petroleum Exporting Countries (OPEC) and American shale producers to control oil production and prices show that the U.S.In the U.S., where shale gas has been commercially exploited for two decades, the prices of fuel and electricity have dropped.However, environmental groups have strongly criticised this move, which they say will have adverse environmental impacts. Under the first phase, shale gas blocks were identified in Andhra Pradesh, Arunachal Pradesh, Assam, Gujarat, Rajasthan and Tamil Nadu. To gain such benefits, the government introduced a policy on shale gas and oil in 2013, permitting national oil companies to engage in fracking. The most common way to extract shale gas is ‘hydraulic fracturing’ (fracking), where high volumes of water mixed with certain chemicals are pushed down to break the rocks and release the trapped energy minerals.įracking seems an attractive tool, both politically and economically. The process of extracting shale oil and gas requires deep vertical drilling followed by horizontal drilling since the shale gas and oil are unconventional natural resources found at 2,500-5,000 m below the earth’s surface, as compared to conventional crude oil found at 1,500 m.
