The Rajasthan block, RJ-ON-90/1, is spread over 3,111 km2 in the Barmer district of Rajasthan. 13 dry wells were drilled in Rajasthan block before Cairn struck ‘black gold’ in the 14th well. The organisation has come a long way since, with numerous discoveries in the Rajasthan block, bringing a number of fields to production, and gearing towards the next phase of growth.

The block has contributed USD 23.7 billion to the nation and the state exchequer as on March 31, 2023. The cumulative production from the Rajasthan block has crossed 700 mmbbls.

Mangala, Bhagyam, and Aishwariya (MBA) are the three largest finds in the prolific Rajasthan block. The Mangala field when discovered in 2004 was considered to be the largest onshore hydrocarbon find in India in the last two decades. This was followed by the discovery of the Aishwariya and Bhagyam fields. Other than MBA, Saraswati and Raageshwari are other key producing fields. To date, 38 discoveries have been made in this block. Studies indicate that the block has further potential for growth.

Till the end of FY2023, RJ Block achieved cumulative total production of over 710 MMBOE, along with the Estimated Gross HIIP of 4.8 billion BOE. The average production of the block during FY23 is 119,888 BOEPD gross production.

The application of the latest technology has been a key facilitator in Rajasthan’s success story. A full field Enhanced Oil Recovery (EOR) polymer flood project has been implemented, the largest such project in the world, which has helped in maintaining the field’s production. The world’s largest Alkaline Surfactant Polymer (ASP) flood project is also under implementation in the block. The waterflood operating expenditure was about US$ 6.4 per barrel, which remains one of the lowest in the world.

The Mangala Processing Terminal (MPT) is spread over 1.6 km2 and is a core asset processing crude oil produced from the various fields in the Rajasthan block. After processing, the crude oil is transported to refineries through the world’s longest and continuously heated and insulated pipeline to the Gujarat coast on the east coast of India travelling across ~ 705 Km to the coastal facility in Bhogat.
