LONDON, Jan 12 (Reuters) - Brent crude oil rose to $98 a barrel on Wednesday for the first time in 27 months as production shutdowns and growing global demand raised expectations of tighter supplies.
A gas leak forced two Norwegian oilfields to be shut down briefly. The Trans Alaska Pipeline, which ships about 12 percent of U.S. crude output, was shut on Saturday because of a leak, although it has been allowed to resume "limited operations".
Brent crude for February <LCOc1> rose 66 cents to $98.27 a barrel by 0924 GMT and climbed as high as $98.46, the highest price in 27 months. U.S. crude <CLc1> added 46 cents to $91.57.
"Worsening sentiment is the only thing that could derail the price rally at the moment," said Carsten Fritsch, analyst at Commerzbank, who said $100 oil looked imminent. "It seems only a matter of time if sentiment remains positive and more disruptions on the supply side come in."
U.S. crude traded more than $7 below Brent on Tuesday, the widest spread since February 2009, because of high inventories at the Cushing, Oklahoma delivery point <CL-LCO1=R> and tighter supply of Brent-related crudes.
Trans Alaska Pipeline operator Alyeska on Tuesday received government permission to restart the line to prevent crude from freezing, a company spokeswoman said, adding flows would resume through the night.
An outage lasting more than a week may force oil refineries on the U.S. West Coast to look for alternatives in Russia and the Middle East, traders and analysts said.
Officials said the line will have to be shut down again in coming days to put a bypass over the leaking section in place. [
]Oil also gained support from forecasts for higher heating demand this week as the U.S. Northeast, the world's biggest heating oil market, prepared for another snowstorm. [

RISING DEMAND, OPEC RESTRAINT
The supply outages come as global oil demand this year is forecast to reach a record level of 88.6 million barrels per day (bpd), following much faster demand growth last year than most analysts expected. [
]At the same time, the Organization of the Petroleum Exporting Countries is sticking to a production-restraining output policy it agreed to more than two years ago, when recession hit demand and prices.
Attention will focus later on Wednesday on the latest snapshot of supplies in the United States, which remains the world's largest oil consumer ahead of fast-growing China.
The U.S. government's Energy Information Administration will release its oil inventories report at 10:30 a.m. EST (1530 GMT).
A Reuters survey forecast U.S. crude oil inventories probably fell 1.1 million barrels last week. [
]According to a report from industry group the American Petroleum Institute on Tuesday, crude oil stockpiles managed a 57,000-barrel gain last week. [
