In 2003, British Petroleum (BP) completed its merger with the Russian Oil company, Tyumen Oil Company, creating a new company called TNK-BP. The company holds oil reserves of 8 billion barrels (SEC estimate, others vary) and produced 1.5 million bbl/d from January-October 2005, making it Russias second-largest oil producer (behind Lukoil). The deal also includes retail outlets in Russia and Ukraine. The company is also an equal partner with Gazprom in Slavneft, which currently produces roughly 500,000 bbl/d.
