LONDON, Nov 28 (Reuters) - Brent oil slipped below $111 per barrel on Thursday, weighed by a bigger-than-expected rise in U.S. crude stockpiles, but Libyan supply disruption kept prices supported.
Brent crude fell 38 cents to $110.93 a barrel by 0944 GMT It is still up 2 percent in November, and over $8 above its low for the month.
U.S. oil fell 12 cents to $92.18, hovering near the lowest in almost six months. It touched a low of $91.77 on Wednesday, its weakest since June 3.
U.S. crude oil stocks rose by almost 3 million barrels to 391 million barrels, their highest level for November since records began in 1982, the Energy Information Administration said in weekly data on Wednesday.
The EIA also said U.S. crude oil output last week exceeded 8 million bpd for the first time since January 1989. Earlier this month, its data showed that crude production exceeded imports for the first time in nearly two decades.
Libyan Prime Minister Ali Zeidan said on Wednesday his government would be unable to pay public salaries and may have to seek loans if armed militias blockading oilfields and ports continue to choke off crude shipments.
Trade is set to be light due to the Thanksgiving holiday in the United States.
"Libya concerns are market supportive still, but nervous jittery trading is here to stay with the U.S. off today volumes will be low," said Andrey Kryuchenkov, strategist at VTB Capital.
Refiners in Europe and the United States are coming back from maintenance and increasing output which has seen demand for crude recovering.
International Energy Agency (IEA) head Maria van der Hoeven said oil markets were adequately supplied even with the prospect of dwindling crude output from Libya.
In addition, Iranian supplies may increase if Tehran follows through on its commitments reached in a breakthrough deal with world powers over its nuclear programme at the weekend.
Brent oil's premium to U.S. crude <CL-LCO1=R> was at $18.92 per barrel, just off its highest level since March.
"This opens a window of competitive advantage to U.S. industry which can only accelerate economic recovery there," Christopher Bellew, broker at Jefferies Bache said.
