The Priobskoye field was discovered in 1982 and put into development in 1988. The total area of the field is 5,446 km2.
Its the largest oil field in Khanty-Mansi Autonomous Area-Yugra, which has a complex geological structure and is considered to be multi-zone and low productive.
The majority of the predicted oil reserves are concentrated in the northern half of the field. The deposit is located on the territory of a compact population of small indigenous peoples of the north, Khanty-more than 50%, Mansi-33%, Nenets-6%, Selkups -1%.
The Priobsky license area developed by Rosneft has initial recoverable reserves of 1.6 billion tonnes and its current recoverable reserves amount to 1.2 billion tonnes as of January 1, 2019.
The cumulative output has exceeded 430 million tonnes of oil. About 25 million tonnes of oil is produced at the field annually, which account for 4.5% of the total Russian production.
The Priobskoye field is estimated to account for over 11% of Rosneft's total oil production.
Since 2019, Rosneft has repeatedly petitioned the government to receive the tax concession for Priobskoye, promising in return to pour additional investments into new drilling and deployment of tertiary recovery methods to raise the field’s declining output.
In February 2021 Rosneft struck a deal with Russia’s Finance Ministry that will hand the country's largest oil producer a large production tax concession for the Priobskoye field. The agreement could see Rosneft saving a maximum of $6.2 billion until the end of 2032.
It is one of the largest fields in Russia by oil reserves, called the Pearl of Western Siberia.
