BEIJING (Reuters) - A subsidiary of Houston-based ConocoPhillips said on Friday that more than 85 percent of oil-based mud from its oil spill in China's Bohai Bay had been recovered and vowed to finish the cleanup by the end of this month.
The oil leak at the Penglai 19-3 oilfield, China's biggest offshore oil field, which started in June, has polluted 840 square kilometers of water, the State Oceanic Administration (SOA) has said.
ConocoPhilips owns a 49 percent stake in the oilfield and acts as the operator, while China's offshore oil specialist CNOOC Ltd has a 51 percent stake.
