LONDON, Oct 12 (Reuters) - Oil prices slipped for a second day on Tuesday, falling towards $82 a barrel after Saudi Arabia signalled OPEC would maintain current production levels and as the dollar rallied against the euro.
Strikes at French ports and at eight of the country's 12 oil refineries on Tuesday slashed output and pushed up prices of oil products, which could carry through to support crude prices.
U.S. crude for November delivery <CLc1> lost 79 cents to $81.42 a barrel by 1353 GMT, off an earlier session low of $80.88, which was down by more than $3 from last week's five-month high of $84.43.
ICE November Brent crude <LC0c1> shed 70 cents to $83.02.
Saudi Arabian Oil Minister Ali al-Naimi said he was happy with the oil market as he arrived in Vienna on Monday for the first meeting of the Organization of the Petroleum Exporting Countries (OPEC) in seven months, to take place this Thursday.
He described prices of between $70 and $80 as "ideal", indicating the producer group's most powerful member had no plans to pursue higher prices. [
]The dollar rose by 0.4 percent against a basket of currencies in Tuesday trade, recovering partly from lows against the euro on Monday. [
]"What we've seen is the dollar is still a bit stronger, not only against the euro but also against a basket of currencies," said Andrey Kryuchenkov of VTB Capital.
A stronger dollar renders dollar-denominated commodities more expensive for non-dollar buyers.
The minutes of the U.S. FOMC meeting on Sept. 21 were awaited for indications on the likely extent of a second round of quantitative easing, commonly referred to as QE2, although many analysts said the market had already priced this in.
"We believe the actual onset of QE2 will further lift oil prices," Michael Lo from Nomura Global Equity Research said in a note. "However, given the different starting points for oil prices and economics between QE1 and QE2, we believe the impact of QE2 will be less pronounced."
OPEC
OPEC has not officially changed its production ceiling since December 2008.
Levels of compliance with implied targets, however, have slipped to 56.5 percent, according to Reuters calculations based on OPEC data, leaving plenty of scope to adjust output informally as the market dictates.
The International Energy Agency, adviser to major industrial countries, is hoping for no surprises from OPEC this week, IEA Executive Director Nobuo Tanaka said.
"We want to request that OPEC will look at the global market carefully, and prices and supply and demand situations, and make flexible judgements and decisions," Tanaka said in a Reuters Insider television interview.
OPEC said in its monthly report on Tuesday there was a broad consensus that oil prices around their current range have helped support economic recovery and promote industry investment.
A Reuters poll showed U.S. crude stockpiles are expected to have risen for a second straight week, adding 1.3 million barrels in the week to Oct. 8 due to higher imports.
Industry group the American Petroleum Institute will issue its weekly inventory report on Wednesday at 2030 GMT, a day later than usual because of Monday's Columbus Day holiday.
Government statistics from the U.S. Energy Information Administration will follow on Thursday at 1500 GMT.
Sanford Bernstein cut its average 2011 U.S. crude oil price forecast by 12 percent on Monday to $90 and its 2012 estimate by 8 percent to $102 due to bulging global inventories.
French oil refineries cut output on Tuesday as a nationwide strike further choked supplies, with workers at major ports and eight out of 12 French refineries going on strike.
The protests are expected to exacerbate thinning crude and gasoline volumes in France, which have already suffered as continued action at the country's largest oil hub of Fos-Lavera rolled into its 16th day on Tuesday. [
