It will come onstream in 2019.


Nov 2016: Niko Resources has put its 10% interest in the D6 deep water block up for sale. Sales volumes are declining due to depletion, partially offset by incremental production from sidetracks and reactivations. Drilling of the first of 2 sidetracks in the MA field began in June.

Jan 2014: India plans to offer at least 56 exploration blocks in its first auction of licenses in 2 years. India is hoping that a recent gas pricing reform will increase interest from foreign companies. Previous exploration rounds were dominated by local firms, mainly ONGC. The ministry plans to invite bids for the blocks in February.

Jan 2014: ONGC will invest US$9 bn to develop oil and gas discoveries in the Krishna Godavari basin. ONGC has made 11 discoveries in Block KG-DWN-98/2, next to Reliance’s KG-D6 Block and Gujarat State Petroleum's Deendayal gas field. The block is divided into a Northern Discovery Area (NDA) and Southern Discovery Area (SDA). Cairn still holds 10% in the block.


Oct 2013: It has been pointed out that only two blocks out of 254 blocks awarded under the New Exploration Licensing Policy (NELP) since 1991 have begun production. This not only reflects the bureaucratic drawbacks of operating in India, but also points to a lack of geological potential and commercial prospects over a large part of the sub-continent.

Oct 2013: ONGC has discovered oil in block KG-DWN-98/2 in the Krishna-Godavari basin off the Andhra Pradesh coast, earlier believed to hold predominantly gas. Oil has been struck in 3 out of 6 appraisal wells drilled and is in addition to the large gas reserves the block is believed to hold. Gas production is planned to commence by 2018.

Sep 2013: The government is allowing state companies to explore for shale oil and gas on acreage already awarded. The policy covers acreage held by Oil and Natural Gas Corp (ONGC) and Oil India. Of about 356 blocks, India's regulator has said 176 could hold shale resources. The wording of contracts for blocks awarded later (e.g. to Reliance, BG and Cairn) has been interpreted to exclude unconventional energy. The ministry is proposing an inclusive licence for future acreage.

Sep 2013: ONGC, with 30%, has approved a US$560 mm project to enhance oil recovery at the Rajasthan oilfields. Cairn India, the operator with 70%, submitted an EOR plan in 2012 for the Mangala oilfield, the largest of the 26 finds it has made in the Barmer district. The joint venture will drill 48 infill wells up to Mar 2014.

Apr 2013: Cairn has made its 26th discovery in the RJ-ON-90/1 block of the Barmer Basin in Rajasthan. Raageshwari-South-1 drilled a 10m oil column within the Dharvi Dungar Formation.

Apr 2013: India may offer 68 blocks in the 10th round of New Exploration Licensing Policy (NELP), 25 in deep waters, 20 in shallow waters and 23 onshore. This will be the second highest offering since NELP began in 1999. The government has awarded 254 blocks in previous rounds. NELP VIII was the largest with 70 blocks offered but only 32 awarded. In NELP VII, 41 blocks out of the 57 were awarded while NELP VI achieved 52 out of 55 blocks.

Mar 2013: Cairn and  ONGC have commenced production from Aishwariya, the third largest field in the Rajasthan Block (RJ-ON-90/1). The Mangala, Bhagyam and Aishwariya (MBA) fields in the Barmer basin currently contribute over 23% of India’s oil production.

Feb 2013: Cairn has approval to drill exploration wells on the  Rajasthan block that will help it boost output to 215,000 bbls per day by March 2014. These will be the first exploration wells on the block in over 5 years. The Mangala oilfield went onstream in 2009 and 170,000 bbls per day are now produced from the block. Cairn plans to drill 30 exploration wells over a period of just over a year.

Jan 2013: Reliance has shut-in its 8th well on the Dhirubhai-1 and 3 (D1&D3) gas fields in the Krishna Godavari basin, KG-D6 block with output at an all time low. Reliance has drilled 22 wells on the fields but has put only 18 on production. They started gas production in 2009 and reached a peak of 20 bcm per year in Aug 2010 before water and sand ingress. The same problem has led to shutting of one-third of the wells on the MA oil field in the same block, onstream in Sept 2008. Reliance has made 1 oil (MA) and 18 gas discoveries in the block.
