According to him, all oil companies annually ensured extended replacement of oil reserves. Tatneft, in particular, displayed 143 percent replacement last year, while smaller oil companies did 147 percent. The share of increase through geological prospecting was 54 percent, Minnikhanov noted.
The share of difficult reserves was 78.4 per cent, with the main oilfields being more than 85 per cent depleted, he added. Owing to in-house technologies, however, Tatneft had for the past 20 years displayed progress in recovery, Rustam Minnikhanov claimed. The company seals over 200 patents annually.
Tatarstan had substantial potential to increase its hydrocarbons, Rustam Minnikhanov claimed. The region has a considerable amount of unrecovered high-viscous oil and slate oil. The year’s target on high-viscous oil is 445 thousand tonnes, while the 2017 target is 2 million tonnes. Slate oilfields are being explored.
Tatarstan accounts for 6 percent of the Russian oil refining, he said. “While in 2006 we processed 6.8 million tonnes, in 2014 it was nearly 17 million tonnes, with the share of export in oil recovery reducing from 62 to 39 per cent,” Rustam Minnikhanov said.
