The company said Monday that it had complied with a government order to suspend all drilling, water injection and production at the affected Penglai 19-3 oil field, one of China's biggest.
Operations are currently stopped at 180 producing wells and 51 injecting wells, for a total of 231 wells, said a statement by Houston, Texas-based ConocoPhillips, which operates the field in a venture with state-owned China National Offshore Oil Corp.
CNOOC, which owns 51 percent of the venture, said the suspension of production in Penglai 19-3 would reduce output by 40,000 barrels a day, in addition to the 22,000 barrels a day lost with the shutdown of the two wells where the spills occurred.
