Three Asian national oil companies have walked away from onshore acreage in Sudan, in part due to more than half-a-billion dollars worth of unpaid oil revenues.
Industry officials said China National Petroleum Corporation (CNPC), India’s ONGC Videsh and Malaysia's Petronas have exited their jointly-operated blocks 2A and 4N as efforts to date to recover more than $500 million from the Sudan government have failed.
