Rosneft expects to increase Taimyr group resource base to 6.5 bln tonnes

MOSCOW. Sept 15 (Interfax) - Rosneft expects to increase the resource base of the Taimyr group of fields, where the large-scale Vostok Oil project is being carried out, to 6.5 billion tonnes, the company said in a press release.

"In the course of comprehensive exploration work at the Vostok Oil project the company has confirmed a substantial increase in crude oil reserves. Based on the drilling results from the wells Zapadno-Irkinskaya 32 and Zapadno-Irkinskaya 54 of the Zapadno-Irkinskoye field at the left bank of the Yenisey River, the Russia's State Reserves Committee has confirmed the discovery of two new deposits with recoverable crude oil reserves of 101.4 million tonnes," Rosneft said.

"Testing at the Peschanaya-1 well of the Payakhskoye field at the right bank of the Yenisey River, before hydraulic fracturing and in a depth interval of about 3,300 meters, showed free flows of water-free oil at a reservoir pressure of 600 atm. The findings substantially exceeded expectations improving the development efficiency of the Payakhskoye field. Preparation is underway for hydraulic fracturing and drilling of a pad of production wells," it said.

"The attained results in combination with the results of 3D seismic surveys conducted at the Taymyr group of fields suggest substantial (about 300 million tonnes) increase in the project's resource base to 6.5 billion tonnes," it said.
