NEW YORK, Jan 24 (Reuters) - Oil fell more than 1 percent on Monday as ample U.S. inventories were seen on the rise and after Saudi Arabia's oil minister expressed concerns about the influence of speculators on prices.
Brent's premium to U.S. benchmark West Texas Intermediate crude <CL-LCO1=R> remained robust and reached $9.76 a barrel intraday on Monday, the highest since it hit $10.37 on Feb. 12, 2009. But the spread narrowed to less than $9, helped by news that trading Hetco had sold a big North sea crude position.

Technical weakness helped pull crude prices lower, brokers and analysts said, with U.S. crude finding support just above the 2011 low of $87.25 struck on Jan. 7.
U.S. crude oil for March delivery <CLc1> fell $1.24, or 1.39 percent, to settle at $87.87 a barrel, trading as low as $87.27 after slipping from an early $89.63 intraday peak.
In London, ICE Brent crude for March <LCOc1> fell 99 cents to settle at $96.61 a barrel, trading from $96.23 to $98.17.
Total Brent trading volume was above 461.600 lots traded on Monday, according to Reuters data, 20 percent above the 250-day average.
Total U.S. crude volume was above 782,300 lots traded with less than an hour of post-settlement trading left, 14 percent above the 250-day average of 685,424 lots.
"The complex is suddenly taking on a heavy feel given its inability to advance along with fresh stock market highs and a rebound in the euro," Jim Ritterbusch, president at Ritterbusch & Associates, wrote in a note.
"Some of today's selling appeared triggered by overnight comments from the Saudi oil minister that implied that additional barrels could become available to the market if demanded while at the same time, the suggestion appeared to be made that moderately lower prices would be desirable."
Brent got an early boost when Saudi Oil Minister Ali al-Naimi, said he expected global oil demand to rise between 1.5 million and 1.8 million barrels per day in 2011 -- more than forecast by the International Energy Agency. [
] [ ]But the Saudi minister also said he expected prices to stabilize and voiced concern about speculators pushing prices higher. Brent prices scaled $99 a barrel as recently as Jan. 14 and some analysts said Naimi voicing concern about speculators may have caused increased investor caution.
Oil trader Hetco sold three North Sea Forties crude oil cargoes on Monday and offered three others. [
]The spot market fell as the company gradually exited a position that at one point had represented about a third of the Forties February program and helped cause the Brent premium to U.S. crude to soar.
Cold weather in the U.S. Northeast and forecasts for more in Europe helped limit U.S. heating oil futures <HOc1> losses on Monday and allowed the heating oil profit margin, or crack spread <CL-HO1=R>, to surge near $24 a barrel intraday, a two-year high. [
]U.S. heating oil demand was expected to average 14.4 percent above normal this week, the National Weather Service said on Monday. [
]AMPLE INVENTORIES WEIGH
Last week, the U.S. Energy Information Administration reported that U.S. crude oil inventories rose 2.62 million barrels last week, against expectations stockpiles would be lower. [
]High inventories, especially at Cushing, Oklahoma, the delivery point for the U.S. crude contract, have helped keep U.S. crude prices in check, while North Sea production problems had allowed Brent to close . [
]A Reuters analyst survey on Monday expected crude stocks to have posted another build last week, with imports expected to be up again and with inventories benefiting from the resumption of the flows in the Alaska pipeline. [
]The seesawing euro and dollar added to oil price volatility. The euro climbed to a two-month high against the dollar as investors pushed the euro through key technical and trading levels on expectations of higher euro zone interest rates.
"There is some concern that around the globe the stimulus from central banks is going away with the improving economic recovery and the threat of inflation," said Phil Flynn, analyst at PFGBest Research in Chicago, citing that as a factor helping weigh on oil prices.
