ConocoPhillips can resume oil work

BEIJING – The Chinese subsidiary of ConocoPhillips can resume operations at an oil field off the coast of northeastern China that was closed in 2011 after two oil spills, a regulator said.

The two spills occurred in June 2011. Combined, they released more than 30,300 gallons of oil, or 723 barrels, and more than 110,000 gallons of mineral oil-based drilling mud, which is used as a lubricant for drilling.
