New Delhi, Jun 17 (PTI): Cairn India, which accounts for 30 per cent of India’s crude oil production, has received environmental clearance for raising production from its prolific Rajasthan fields by 50 per cent to 300,000 barrels per day (15 million tonnes a year).
Environmental clearance has been granted to Cairn India to augment hydrocarbon production from the RJ-ON-90/1 block in Barmer and Jalore districts of Rajasthan to 300,000 barrels of oil per day from current limit of 200,000 bopd, sources privy to the development said.
Cairn had made 31 oil and gas discoveries in the Rajasthan block, of which four -- Mangala, Bhagyam and Aishwariya (together known as MBA fields) and Raageshwari -- have been put on production.
The output had touched 200,000 bpd in March but the block is currently producing about 190,000 bopd, they said.
Cairn’s Rajasthan fields account for a quarter of India’s domestic crude oil production of 190,000 bpd.
Since the resumption of exploration in March last year, the company has successfully opened up five new play types, proving up a resource base of over 1 billion boe in place.
The company has initiated enhanced oil recovery programme at its Mangala field, the largest in the Rajasthan block, to raise recovery and support output from the field in the longer term.
Sources said two new gas prospects have been found in the block, prompting Cairn to set up a gas processing plant at its existing Raageshwari gas terminal for processing 100 to 300 million cubic feet gas per day.
Raageshwari field is a major gas field, located down south of the Rajasthan block. Gas from Raageshwari field is currently processed at Raageshwari Gas Terminal (RGT) located abut 80km from Mangala oil Processing Terminal (MPT).
”We have plans to upgrade the existing Raageshwari Gas Terminal and are looking at options to construct a new gas pipeline to monetise the additional gas potential in the block,” Cairn had previously stated.
