Oil and gas production fell by 14 percent to 275,000 barrels of oil equivalent (boe) per day in April-June, from 318,000 boe per day in the same period last year.

This was "mainly due to the ongoing political instability in Libya and Yemen," OMV said in a statement.

Oil production alone fell by 39,400 barrels per day from the second quarter of 2010, it said, without however giving the figures for April-June 2011.

A pipeline was damaged in the first quarter in the political unrest in Yemen but has now been repaired, although OMV warned that resuming production may still take a while.

The company's final statement will come out on August 10.
