LONDON, Feb 25 (Reuters) - Oil retreated from highs, briefly turning negative, on Friday as top exporter Saudi Arabia said it was willing to step in to make up for any shortages as a result of a disruption to oil supplies from Libya.
ICE Brent crude futures <LCOc1> was up 25 cents at $111.61 a barrel by 0912 GMT, retreating from $113.91 earlier in the day. It touched a two-and-half year high of $119.79 on Thursday.
U.S. crude futures <CLc1> was up 27 cents at $97.55, off $99.20 earlier in the day, It hit $103.41 on Thursday, its highest since September 2008.
Unrest in Libya has cut a large chunk of the North African and OPEC member country's output of 1.6 million barrels per day (bpd), and a senior Saudi official on Thursday said Saudi Arabia was in talks with European companies affected by the disruption. [
]The estimates of shut-in volume varies. The International Energy Agency said Libyan oil output to have been cut by 500,000 to 750,000 bpd due to the unrest, while Italian oil company ENI <ENI.MI> said as much as 1.2 million bpd may be down. [
]Still, key Libyan crude and oil product terminals east of the capital are in the hands of rebels who have seized control from leader Muammar Gaddafi. [
]The unrest in Libya followed massive protests in Tunisia and Egypt which led to the toppling their long-time leaders and has spread to other Middle East Gulf nations.
"When geopolitics in the Middle East are at play in the oil markets, all conventional bets on the direction of oil prices based on supply and demand fundamentals, or economic variables, are off," analysts at BNP Paribas said in a research note.
The Libyan supply outage and concern that supply problems may spread has driven up short-term prices for oil more than those for later dates and led to the return of backwardation in the Brent crude market.

Saudi Arabia is the only oil producer with significant spare capacity to meet global supply outage volume such as the reduction in the flow from Libya.
Physical oil traders, however, said the difference in qualities between Saudi and Libyan oils may make it difficult to fill in the supply gap immediately. (Additional reporting from Randy Fabi in Singapore; Editing by Jason Neely)
