Samotlor Field is the largest oil field of Russia and the sixth largest in the world,[1] owned and operated by TNK-BP. The field is located at Lake Samotlor in Nizhnevartovsk district, Khanty–Mansi Autonomous Okrug, Tyumen Oblast. It covers 1,752 square kilometres (676 sq mi).[2]


The field was discovered in 1965. Development started in 1967 and first oil was produced in 1969.[1][2] Discovery of this field had changed Nizhnevartovsk from a small nearby village into a busy oil city as Samotlor used to be the most important oil production base of the Soviet Union. Before forming TNK-BP, the field was developed by Samotlorneftgaz and TNK-Nizhnevartovsk.[3] After creation of TNK-BP, these companies became subsidiaries of TNK-BP.

Over the all development period a total of 2,086 well clusters (containing more than 17,000 wells) have been built and about 2.6 billion tons of oil has been produced.[1][2] The peak production occurred in 1980 when Samotlor produced 158.9 million tons of oil (7 Mbbl/d or 1.1×10^6 m3/d).[2] The production has been in decline ever since, although according to TNK-BP the field production has stabilized over the past last years after.[1]


The in-place oil reserves of the Samotlor field were equal to 55 billion barrels (8.7×10^9 m3) and as of 2009 estimated at 1 billion barrels (160×10^6 m3). The proven reserves are approximately 44 billion barrels (7.0×10^9 m3).[4] The field is 80% depleted with water-cut exceeding 90%.[1]

At the end of the 1990s, production rate dropped to 300,000 barrels per day (48,000 m3/d).[5] However, through an aggressive exploration program and application of cutting-edge technologies TNK-BP had raised production up to 750,000 barrels per day (119,000 m3/d).[1] Up to 2012, TNK-BP plans to invest US$1 billion per year for maintaining oil production in it at the level of 30 million tons per year.[4]
