CNOOC Agrees a Plan with ConocoPhillips to Stop Further Oil Leaks in Bohai Bay

According to the plan, ConocoPhillips will reduce pressure at the site by pumping out fluids used in the oil-production process.

ConocoPhillips' state-controlled local partner in a Chinese offshore oil project said Monday it has approved a plan raised by the U.S.- based company to reduce the likelihood of further leaks in the Penglai 19-3 oilfield in Bohai Bay.

China National Offshore Oil Corp. (CNOOC), who owns 51 percent of the field, also said that it would monitor the implementation of the plan and evaluate the effect.

According to the plan, ConocoPhillips will reduce pressure at the site by pumping out fluids used in the oil-production process. Both companies have said the plan would not guarantee any restart of oil production from the now-shut fields.

ConocoPhillips halted production activities at 235 wells including 181 producing wells and 54 injecting wells ordered by the government after oil leaks, which started on June 4 and June 17 respectively, have polluted more than 5,500 square kilometers of water in Bohai Bay, according to the monitoring results from local water-management agency.

ConocoPhillips also disclosed in a statement Monday a preliminary result on the reason of the leaks. Oil leaks at Platform B was a first-ever accident of oil leaks in the seabed of the oilfield, while at Platform C, leaks of mineral oil-based mud was due to unforeseen high-pressure belt during the drilling.

That seems to disaccord with the State Oceanic Administration's investigation result, which showed that the company failed to carry out the overall development plan when operating at the two platforms.
