The Vankor Field (Ванкорское нефтегазовое месторождение) is an oil and gas field in Russia, located 130 kilometres (81 mi) west of Igarka in the Turukhansk District of Krasnoyarsk Krai in Eastern Siberia, close to the border with Yamalo-Nenets Autonomous Okrug.

[1] Its estimated reserves are 520 million metric tons of oil and 95 billion cubic meters of natural gas.

[citation needed] The field is operated by Russian national oil company Rosneft through its subsidiary Vankorneft.

In 2001, London-based Sibir Energy made a takeover bid to the Anglo-Siberian Oil Company to gain access to Vankor field.

[3] In 2002, TotalFinaElf wanted to buy 52% of the Vankor field development project, but the deal was not closed because of legal difficulties.

[4][5] In 2003, the Anglo-Siberian Oil Company was acquired by Rosneft as the result of a public bid on the London Stock Exchange, and the deal with Total was canceled.
