PARIS (AP) — An official with the International Energy Agency says Libya could return to full oil output slightly faster than predicted but that all estimates are a “shot in the dark.”

The agency officially expects Libya to be pumping around 1 million barrels a day by the end of next year; others have said Libya will reach its full pre-war production of 1.6 million barrels by then.

On the sidelines of a meeting in Paris of energy ministers and industry leaders, David Fyfe acknowledged Wednesday that the IEA’s estimates are conservative, but he said the situation was hard to read.

He said that damage to wells did not seem too bad, but that it seemed the Libyans would have trouble getting the oil out of the country.
