NEW YORK/LONDON, Dec 23 (Reuters) - Oil shot to a more than two-year high for a second day in a row on Thursday, and some analysts said a run at $100 a barrel is inevitable, as one key OPEC member expressed little alarm over the rally.
With ultra-cold weather stoking demand and helping drain U.S. stockpiles at the fastest pace in 12 years, traders are now looking for the Organization of the Petroleum Exporting Countries to signal when it might begin pumping more crude.
But Libya's top oil official, one of OPEC's most hawkish members toward oil prices, appeared unconcerned by the gains which have lifted prices more than 20 percent in three months as fundamentals turn more positive and investors factor in an improving economic outlook for next year.
"It's fair to say it (the price) is about right, but still I think that it needs to improve a little bit more. About $100 would be a fair price for the time being," Libya's National Oil Corp Chairman Shokri Ghanem told Reuters in Cairo ahead of a meeting of Arab oil exporting countries.
"I think current oil prices are reflecting the situation in the market which is a well-balanced market," he said.
U.S. crude for February <CLc1> rose 62 cents to $91.10 a barrel by 11:37 EST (1637 GMT), the highest price since Oct. 7 when oil prices were crashing from their $147 record as the world's financial industry reeled and investors fled risky assets.
ICE Brent crude <LCOc1> rose 47 cents to $94.12, with a midsession burst of gains triggered by buy-stops after prices broke above Wednesday's high and as the dollar fell.
Nearly three years after oil first traded at $100, demand is again rising swiftly, but one key factor has changed significantly. Unlike the start of 2008, when OPEC was already pumping flat out, the group now has a sizeable amount of idle capacity it could use to douse the rally -- if it chooses.
A series of comments in recent months suggest the cartel is now ready to tolerate a price higher than the $70-to-$80 band it has publicly supported for the past two years, and analysts say that means it may wait too long before pumping more oil.
"With OPEC set to be reactive rather than proactive, the route to $100 appears fairly unobstructed at this time," said analysts at Barclays Capital.
Oil traders will be looking for comments this weekend from other core Gulf OPEC ministers to see if they are more concerned than they were two weeks ago when the group decided at its meeting in Quito, Ecuador, to maintain supply quotas.
The meeting of the Organization of Arab Petroleum Exporting Countries (OAPEC) in Cairo will not set policy, and OPEC's next formal meeting is not scheduled until June.
But some analysts say they expect the group to quietly lift output prior to that by leaking more beyond quotas.
"I think we are going to see more production because oil is above $90," said Patrick Armstrong of London-based Armstrong Investment Managers. "But I don't think we're going to see scenarios for spikes."

FASTEST DRAW IN THE WEST
Unusually cold weather in the United States and Europe has helped to spur the latest leg of a more than 30 percent rally from a year low struck in May.
Brightening prospects for next year are also fuelling the market. Data on Thursday showed new U.S. claims for jobless benefits dipped last week and consumer spending increased in November for a fifth straight month, reinforcing views of a solid economic growth pace in the fourth quarter. [
]After a contraction in demand following the global economic recession, fuel use has begun to rebound and is expected to continue growing next year, taking absolute oil consumption to an all-time high. But the rate of growth will still be lower than a peak hit in 2004. [
]Gains this week have been fuelled as much by momentum trading in a thinner holiday period as by improving fundamentals, including another big weekly draw in U.S. crude stocks. Inventories have now fallen 19 million barrels in three weeks -- the biggest decline since 1998.
"In the (U.S. inventory) report per se there was nothing apart from a normal seasonal draw-down," said Olivier Jakob of Petromatrix.
"The market is currently only interested in a technical attack of the recent highs," he said, adding prices could also be exaggerated by thin trade over the holiday period. (Additional reporting by Randolph Fabi and Seng Li Peng in Singapore; editing by James Jukwey and Jim Marshall)
