Chevron replaces BP as third-biggest oil major

LONDON, Oct 27 (Reuters) - U.S. oil major Chevron Corp (CVX.N) has replaced Britain's BP Plc (BP.L) as the third-largest non-government controlled oil company in the world, as problems in Russia and currency weakness have hit BP.

BP's market capitalisation was $131.2 billion as measured by Friday's closing prices, compared with $131.3 billion for Chevron.

BP was the industry's number two until it was overtaken by Royal Dutch Shell Plc (RDSa.L) after BP's valuation was hit by the Texas City refinery explosion in 2005, which killed 15 workers, and by big project delays.

Exxon Mobil (XOM.N) is the largest listed international oil company, with a market capitalisation of $358.6 billion.

BP's shares traded down another 3.92 percent at 422-3/4 pence at 1214 GMT on Monday. (Reporting by Tom Bergin, editing by Will Waterman)
