Rosneft confirmed a substantial increase in its resource base to 6.5 billion tons, about 300 million tons, in the course of comprehensive geological exploration work under the Vostok Oil project. Thus, the state committee approved the discovery of two new deposits with 101.4 million tons of recoverable oil reserves, based on the results of drilling at the Zapadno-Irkinskoe field. And at the Payakhskoye field, a water-free oil fountain was obtained at a reservoir pressure of 600 Atm, which exceeds forecast characteristics and improves the efficiency of field development.
