Rajasthan Hydrocarbon Basin: Oil-Natural Gas

Rajasthan Hydrocarbon Basin: Oil-Natural Gas

The Rajasthan Hydrocarbon Basin is a sedimentary basin located in western Rajasthan with a geographical extent of about 1,50,000 square kilometres.  The basin is spread over 14 districts under 4 petroliferous basins.

Crude Oil Production in Rajasthan

Rajasthan is a significant producer of crude oil in India. The State contributes about 22-23% (7 million metric tonnes per annum) of total crude oil production (32 MMTPA) in India and is the second largest producer after Bombay High which contributes about 40%.

Commercial Production of crude oil commenced from Mangla Field on 29th August, 2009 and at present about 1,15,000 barrels of oil per day is being produced from 14 fields i.e. Mangla, Bhagyam, Aishwarya, Saraswati, Raageshwari, Kameshwari and other satellite fields.

Rajasthan Basin Location:

Rajasthan Basin forms the eastern flank of Indus geosyncline and comprises the sedimentary tract to the west and northwest of Aravallis upto Indo-Pakistan border. This pericratonic basin also forms a part of the great Thar Desert.

Rajasthan Basin: Sub-Basins:

Rajasthan Basin has been sub-divided into four potential Petroliferous basins,  separated from each other by basement ridges/faults. These four Basins are spread over in 14 Districts of Western & Eastern Rajasthan. The Ministry of Petroleum & Natural gas has upgraded the first three petroliferous basins into category- I, i.e. equivalent to the Bombay High, Cambay Basin and Assam, which are potential for hydrocarbons prospects.
