(Reuters) - Oil prices dropped to fresh 5-1/2-year lows on Monday as worries about a surplus of global supplies and lackluster demand dragged on oil markets.

Russia's oil output hit a post-Soviet high last year, averaging 10.58 million barrels per day (bpd), up 0.7 percent thanks to small non-state producers, Energy Ministry data showed.

Iraq's oil exports were at their highest since 1980 in December, an oil ministry spokesman said, with record sales from the country's southern terminals.

But oil producer group OPEC has decided not to cut output, opting to let the market find its own level.

The two oil benchmarks - Brent and West Texas Intermediate - have now lost more than half of their value since mid-2014. Brentcrude for February dropped as low as $55.25 a barrel, its weakest since May 2009, before edging back to $55.67, down 75 cents, by 0815 GMT.

U.S. crude slid to $51.40 a barrel on Monday, also its lowest since May 2009, before recovering a little to trade around $51.90.

"It's hard to see much improvement in oil fundamentals near term," Morgan Stanley analyst Adam Longson said.

"New supply has entered the market, offsetting Libya woes. Additional exports are coming primarily from Russia and Iraq."

Lackluster economic data from the United States on Friday fueled worries about the state of the global economy and the strength of oil demand.

"Oil demand is unlikely be robust this year when we look at the state of economies in China,Japan and Europe," said Yusuke Seta, a commodity sales manager at Newedge Japan.

Investors are also increasing bets on lower oil prices.

Open interest for $40-$50 strike puts have risen several fold since the start of December, while $20-$30 puts for June 2015 have traded, said Stephen Schork, editor of Pennsylvania-based The Schork Report.

Conflict in Libya has reduced the OPEC producer's crude output to around 380,000 bpd, state-run National Oil Corp (NOC) has said.

Fighting was reported near the country's biggest oil export port Es Sider in the east even as a week-long fire at the port's storage tanks was extinguished on Friday.
