OMV, during a news conference, said it expects to restore its Libyan production to levels of reliability seen before the civil war by the end of 2012.

"There's work ongoing. It will take most of the rest of this year to get back to the sort of reliability levels we've seen previously," Jaap Huijskes, OMV's head of exploration and production, told the news conference.

"The fields are OK. It's the reliability, the up time that we're still working on," said Huijskes. The company said earlier that Libyan production would likely remain stable at around 90% of pre-crisis levels for the time being.
