NEW YORK, Feb 25 (Reuters) - Brent oil rose in volatile trade on Friday to hold above $112 a barrel but below Thursday's 2-1/2-year highs after Saudi Arabia raised output to calm fears of supply disruptions sparked by Libya's uprising.
Saudi Arabia has boosted output by more than 700,000 barrels per day, to a level exceeding 9 million bpd, a senior industry source familiar with Saudi production told Reuters. [
]Worries about the worsening situation in Libya, where oil outages have risen to as much as three quarters of its 1.6 million bpd output, spurred short-covering before the weekend.
Those moves were further stoked by news that the United States was imposing sanctions and cutting diplomatic ties with Libya as Muammar Gaddafi's security forces cracked down against a widening revolt against his rule. [
]"I don't think many traders are comfortable being short over the weekend," said Tom Bentz, a broker at BNP Paribas Commodity Futures in New York.
Estimates of Libya's supply loss could not be confirmed, however, with conditions unsettled as rebels fought to wrest control of oilfields and terminals in the east of the country from Gaddafi loyalists. [
]On Thursday, the disruptions pushed Brent to almost $120 and U.S. crude to more than $103. Brent shot ahead as more of Libya's oil exports go to European refiners than to those in the United States.
In London, Brent futures <LCOc1> for April closed up 78 cents at $112.14 a barrel, the highest weekly settlement since Aug. 21, 2008. They peaked at $113.91, below Thursday's high of $119.79, the loftiest intraday since August 2008.
U.S. April crude futures <CLc1> settled up 60 cents at $97.88, the highest weekly close since September 2008, and reached $99.20 earlier. That was well below Thursday's intraday peak of $103.41, also the highest since September 2008.
Brent's premium against U.S. crude <CL-LCO=R> rose to $14.26, from $14.08 at the close on Thursday, when the Brent spread against U.S. benchmark West Texas Intermediate rocketed to a record $16.91.

"Fears that the unrest in Libya could turn into a civil war and wipe out its oil production have been offset by assurances from Saudi Arabia that it is raising output," said Gene McGillian, analyst at Tradition Energy in Stamford, Connecticut.

U.S. crude drew support from a rise in consumer confidence to a three-year high in February, suggesting the economy remained on a solid footing despite high gasoline prices, according to a ThomsonReuters/University of Michigan survey. [
]That optimism was tempered by the latest reading of fourth-quarter 2010 economic growth, which showed the U.S. economy grew more slowly than expected. (Additional reporting by Ikuko Kurahone and Nia Williams in London, Randy Fabi in Singapore; Editing by Dale Hudson)
