3. Rosneft Oil
The government-owned oil producer saw revenues jump 65% in 2007 to $36.2 billion and net income doubled to $4.17 billion in the second quarter of 2008. Rosneft currently holds the Vankor Field in eastern Siberia, one of Russia's short-term prospects for boosting the country's lagging production. The company announced in July that it would send production from the region to Western refineries operated by TNK-BP. In exchange, TNK-BP will convey oil from the Samotlor oil field to Rosneft's refineries in eastern Siberia. The swap operation won't start until 2010.
