China’s State Council has ordered an investigation into a huge spill at an oilfield co-owned by US energy giant ConocoPhillips (COP.NYSE, YCP.ETR) and state-owned China National Offshore Oil Corp (CNOOC; CEO.NYSE), the AFP reported. In a meeting chaired by Wen Jiabao, the cabinet vowed Wednesday to punish those found responsible. Production was halted Monday at the Penglai 19-3 oil field, the site of a spill first uncovered in June that has now leaked roughly 3,200 barrels of oil into northern China’s Bohai Bay. Chinese state media have heavily critized ConocoPhillips for the spill, accusing the Houston-based firm of displaying “indifference” and attempting to cover-up the disaster. ConocoPhillips, which has denied any cover-up, apologized on Wednesday and said it was setting up a fund to address its legal responsibilities and improve the environment of Bohai Bay. CNOOC announced earlier this week that its oil output for the year would be reduced due to the halt in operations at the Penglai field, which first began production in 1999.
