The Samotlorskoye field is the largest oil field in Russia and the sixth largest in the world, located on Lake Samotlor in the Nizhnevartovsk district of the Khanty-Mansi Autonomous Okrug of the Tyumen Region.
The Samotlorskoye field was discovered in 1965 and put into commercial development in 1969. Industrial oil and gas potential has been identified in 18 productive strata associated with the Jurassic and Cretaceous systems, lying at depths from 1600 to 2500 meters. The initial flow rate of wells is 47-1200 tons per day.
In 1981, a billion tons of oil was produced at the field. In 1986, 2 billion tons of oil were produced. Peak oil production (about 150 million tons. per year) occurred at the beginning of the 80s of the XX century; due to intensive production in these years, oil-bearing formations began to be watered and oil production declined sharply.
In 1996, 21.56 million tons of oil were produced. In the XXI century, due to the use of modern methods of intensification of oil production, oil production has doubled. In total, over the years of operation of the field, more than 20,899 wells have been drilled, more than 2.8 billion tons of oil have been extracted, the extraction from the bottom is more than 75%, the multiplicity of reserves in relation to current production is 47 years.
