Moscow, December 18, 2002. Sibneft and Tyumen Oil Company (TNK) today jointly participated in the largest privatization in the history of the Russian Federation. Acting in the interests of Sibneft and TNK, Invest-Oil, an affiliated company, entered the winning bid of $1.86 billion at an auction held by the government of the Russian Federation for a 74.95% equity stake in Slavneft.

Slavneft, Russia’s 9th largest oil producer, has estimated proved oil reserves of 2.54 billion barrels, and annual production of 13.93 million tons (275 thousand barrels per day). The company also controls the Yaroslavl and Mendeleev Refineries with annual throughput of 11.89 million tons (235 thousand b.p.d.), and operates the Mozyr Refinery in Belarus.
