OVL, the overseas arm of state-owned Oil and Natural Gas Corp (ONGC), had last year bought 15 per cent stake in the field for USD 1.268 billion. It paid an additional USD 930 million for another 11 per cent stake.
The firm and its wholly-owned subsidiary ONGC Videsh Vankorneft Pte Ltd, Singapore "jointly signed definitive agreements with Rosneft, the national oil company of Russia for acquiring additional 11 per cent shares in JSC Vankorneft, a company organized under the law of Russian Federation which is the owner of Vankor Field and North Vankor license," the company said in a statement.
The agreement was signed by Narendra K Verma, CEO & Managing Director, on behalf of OVL and Igor Sechin, Chairman Board of Directors, Rosneft in Moscow.
Vankor is Rosneft's (and Russia's) second largest field by production and accounts for 4 per cent of Russian production.
The daily production from the field is around 4,21,000 barrels per day of crude oil on an average and together with earlier acquisition of 15 per cent, OVL's share of daily oil production from Vankor will be about 1,10,000 bpd.
