Oil rose above 107 dollars a barrel on Tuesday as cold weather across the central United States threatened production.
Also, Libya’s navy opened fire as a tanker approached to load crude at the seized port of Es Sider, dampening the prospect of a further output recovery.
The restart of the major El Sharara oilfield had led to a drop in prices in the past few days.
“There is still no sign of any solution to the crisis for six months now, nor of any normalization of oil production,” said Carsten Fritsch, analyst at Commerzbank in Frankfurt.
Brent crude had gained 41 cents to 107.14 dollars , after settling lower in the previous five sessions, partly on expectations of rising Libyan exports. U.S. crude was 39 cents higher at 93.82 dollars.
Production is building up at the 340,000-barrel-per-Oilday (bpd) El Sharara, which as of Monday was pumping 205,000 bpd.
A return to full output will more than double Libyan production, which had fallen to 250,000 bpd from 1.4 million bpd in July.
Analysts said the field’s return was unlikely to push prices much lower.
“I think the restart of production is priced in by now. Maybe it’s even overshot to the downside,” said Tony Nunan, oil risk manager at Mitsubishi Corp in Tokyo.
Oil was also supported by severe cold weather in the central United States that threatens to curtail some oil production as wells were stranded and drilling operation was interrupted.
Still, as of Monday, major U.S. oil producers had only reported minor effects on their operations. Temperatures were forecast to return to normal levels in Texas and North Dakota by Wednesday.
U.S. crude oil stockpiles have fallen by more than 30 million barrels in the last five weeks – the biggest such decline since 1990.
Again, Gulf Coast refiners drew down stocks to minimize year-end taxes.
That trend could be broken this week as inventory reports from the American Petroleum Institute and the Energy Information Administration are expected to show a 2.2 million-barrel increase in supplies.
