NEW YORK, Aug 14 (Reuters) - Brent crude oil prices hit a 4-month high on Wednesday on concerns over Middle East supply disruptions, reversing earlier losses as investors booked profits from a recent rally.
Libya's deputy oil minister said on Wednesday that production had fallen to 600,000 barrels a day due to field problems while Ras Lanuf terminal remained shut, a day after the state-run oil company said it could not promise crude deliveries next month because of labor unrest at its sea terminals.
Chaos reigned in Egypt as violence continued across the country and the government imposed a state of emergency after dozens were killed in clashes between riot police and supporters of ousted President Mohamed Mursi.
Interim vice president Mohamed ElBaradei resigned from his post after the clashes, which killed 149 people, according to the Egyptian health ministry.
"Fresh headlines out of Egypt are the primary concern right now," said Stephen Schork, editor of The Schork Report in Villanova, Pennsylvania.
"The situation in Egypt doesn't seem to be getting any better and in fact it seems to be getting worse."
Egypt's Suez Canal, an important supply route for Middle East oil, was unaffected by unrest in the country, shipping sources said on Wednesday.
Egyptian ports were operating normally, but delays to berthing of ships could occur later with the imposition of a curfew starting this evening, one Egyptian shipping source said.
Brent rose 8 cents at $109.90 at 12:22 EDT (1622 GMT), but retraced gains after earlier hitting a four-month high of $110.31.
U.S. oil fell 30 cents to $105.53, paring earlier losses of more than $1.
The U.S. crude front-month contract briefly turned positive after data from the U.S. Energy Information Administration showed a 2.8 million-barrel draw in U.S. crude inventories, before turning negative again. Inventories at the Cushing, Oklahoma delivery point fell for the sixth straight week, reaching their lowest level in 17 months.
Analysts said the numbers, while encouraging, were not enough to spark a rally.
"We had a large draw in crude stocks in the APIs, and we continued to see Cushing fall, but the fact is, demand numbers aren't increasing," said Gene McGillian, analyst at Tradition Energy in Stamford, Connecticut.
Oil prices also shrugged off earlier data suggesting the euro zone's longest ever recession was over, with analysts noting that still-sluggish growth figures and cuts in throughput at European refineries pointed to weak demand.
"I think it is at these levels that Brent will run out of steam," said Christopher Bellew, an oil trader at Jefferies Bache.
"The September contract is about to expire and... there has been a great deal of speculative length."
Brent oil futures for September delivery had risen for a third straight session on Tuesday, touching their highest in nearly two weeks at $110.06 a barrel as investors fretted that unrest and maintenance work would continue to disrupt supply in Libya and Iraq.
Maintenance at Iraq's southern oil export hub is also set to slash supplies by 500,000 barrels per day in September.
