CNOOC International, the international division of CNOOC Limited, is a global energy company with operations in Asia, Africa, the Americas, the Middle East and Europe.

In Canada, CNOOC International has oil sands assets in Long Lake, located in northern Alberta just south of Fort McMurray, which is a SAGD and partial Upgrader operation with production capacity of 85,000 barrels of bitumen a day. We also have interest in several other oil sands projects, including Hangingstone, operated by Greenfire Resources Operating Corporation and Syncrude’s oil sands mining upgrading facility. In addition to our oil sands business, we have shale gas land in Northeast British Columbia, a power station in Balzac, Alberta, and interest in a wind farm in southern Alberta. Calgary is our regional corporate office for all North America.
