India has an estimated sedimentary area of 3.36 million sq km, comprising 26 sedimentary basins, out of which, 1.63 million sq km. area is on land, 0.41 million sq km is in the shallow offshore area up to 400m from the coast, and 1.32 million sq km in the deepwater area beyond 400m.
Over the past few years, the unexplored part of this vast area has come down significantly as a result of the surveys carried out by DGH and acreages awarded.
In its move to achieve the target of 1 million square kilometers under exploration by 2030, and reduce the ‘No-Go’ areas in the Indian offshore sedimentary basins by 99 per cent, the Centre has rolled out a series of measures to make oil and gas exploration easier for companies.
