The National Iranian Oil Company (NIOC) still owes Austrian oil and gas group OMV $148 million, OMV's exploration and production chief Johann Pleininger told a meeting of shareholders on Wednesday.
"We are in intensive negotiations to complete the relevant contracts to settle the claims," Pleininger said.
Chief Executive Rainer Seele had previously declined to name the outstanding amount but has said the issue stood in the way of making quick progress with OMV's business in Iran.
