LONDON, Jan 11 (Reuters) - Oil steadied above $89 per barrel on Tuesday, paring early gains on expectations that a key Alaskan pipeline would resume operations within a few days.
The 800-mile (1,280-km) Trans Alaska Pipeline, which carries oil from Alaska's North Slope, was closed after a leak was discovered on Saturday, shutting in flows equivalent to 12 percent of U.S. crude output. [
]U.S. crude for February <CLc1> was little changed on the day by 0845 GMT, down 15 cents at $89.10 a barrel after trading as high as $89.67 at the start of the session.
Officials said on Monday the Alaskan pipeline should reopen later this week. Producers in Alaska's Prudhoe Bay region have cut output by about 600,000 barrels per day (bpd) to just 5 percent of normal levels.
Traders said they saw the closure of the pipeline as only a temporary support for oil prices.
A bypass line at the affected area would allow the duct's operator, Alyeska Pipeline Service Co, to restart the system. Past shutdowns have generally been short-lived, and tanker shipments from Alaska's Valdez port have not yet been hit.
"We do not believe that this interruption will translate into any meaningful disruption (to oil supply) as stockpiles remain more than adequate," said Edward Meir, senior commodity analyst at brokers MF Global.
"Consequently, some of (the) gains could be rolled back later in the week, particularly once the current cold snap gripping the eastern half of the U.S. recedes."
U.S. INVENTORIES
U.S. crude oil inventories probably rose by 400,000 barrels last week as imports rebounded, in what would be the first gain in six weeks, according to a preliminary Reuters poll before the release of weekly inventory reports. [
]Industry group the American Petroleum Institute will publish inventory statistics on Tuesday at 2130 GMT, while the U.S. Energy Information Administration will follow with government figures on Wednesday at 1530 GMT.
In the previous five weeks, crude inventories had tumbled more than 24 million barrels, the biggest five-week drop since June 2008, as refiners, in their usual year-end practice, used more of their stored supplies and tried to hold down imports to lower their taxes for 2010. [
]Distillate stocks, which include heating oil and diesel, may have increased 1.3 million barrels for their third straight weekly gain, while gasoline stocks probably rose 2.8 million barrels, the survey showed.
Front-month ICE Brent crude <LCOc1> shed 40 cents to $95.30 by 0845, maintaining a hefty premium of more than $6 over U.S. crude, supported by a combination of tight North Sea crude supplies and disruption of oil grades priced off it.

The closure of the Alaskan pipeline has also encouraged consumers to buy North Sea crudes, traders say, and is also likely to support Middle East crudes, such as Oman.
China's crude oil imports rose 17.5 percent to a record 4.79 million bpd in 2010 from a year ago, official data showed on Monday, but the growth may slow this year as fewer new refineries come on stream. [
]In other markets, the euro languished near a four-month low on Tuesday after a brief rally triggered by a Japanese plan to buy euro bonds, while Asian stocks drifted, fearful of Portugal becoming the next casualty of the euro zone's debt crisis. [
