China National Petroleum Corp./PetroChina Co. Ltd.

摘要

China National Petroleum Corp. (CNPC) and subsidiary PetroChina Co. Ltd. may be China's biggest oil and gas company, but the companies have expanded operations into shale in Canada and coalbed methane (CBM) in Australia. CNPC bought a half interest, with Shell holding the other 50%, in Australia's Arrow Energy Ltd., one of that country's largest CBM producers, with prop- erties in the Bowen and Surat basins in Queensland and in New South Wales.
