China says ConocoPhillips unit can resume operations at oilfield closed after leaks in 2011

A Chinese regulator says the Chinese subsidiary of ConocoPhillips can resume operations at an oilfield that was closed in 2011 after two oil spills.

The State Oceanic Administration said in a statement Saturday that conditions at the Penglai 19-3 oilfield had returned to normal after a series of rectification measures. It says ConocoPhillips can gradually resume production there.

The oilfield off northeastern China is jointly owned by ConocoPhillips' Chinese subsidiary and China National Offshore Oil Corp., China's main offshore oil and gas producer.

The two spills occurred in June 2011. Combined, they released more than 30,300 gallons of oil, and more than 110,000 gallons of mineral oil-based drilling mud, which is used as a lubricant for drilling. The oil and mud drained into the Bohai Sea and its bay.
