China National Offshore Oil Corporation

China National Offshore Oil Corporation (CNOOC) is primarily engaged in the exploration, development, production, and processing of offshore oil and natural gas resources. The corporation also conducts related activities such as pipeline transportation, liquefied natural gas (LNG) processing, and the marketing of petroleum products. Its operations span both domestic fields along China’s coastline and overseas projects in regions including Africa, Southeast Asia, and the Americas. CNOOC supplies energy to industrial users, power generators, and retail markets within China and abroad.

As one of China’s three state‑owned national oil companies, CNOOC holds a significant position in the nation’s offshore energy sector and contributes to national energy security. The company is recognized for its technical expertise in deep‑water drilling, subsea production systems, and offshore platform engineering. It frequently collaborates with international oil firms through joint ventures and production‑sharing agreements to access advanced technology and expand its resource base. CNOOC’s portfolio includes a variety of offshore assets ranging from shallow‑water fields to ultra‑deepwater developments.

CNOOC is a wholly state‑owned enterprise supervised by the State‑owned Assets Supervision and Administration Commission (SASAC) of the State Council. Its flagship listed subsidiary, CNOOC Limited, is traded on the Hong Kong Stock Exchange and holds a portion of the group’s overseas assets while the parent retains control of core domestic operations. The corporate structure allows CNOOC to balance state oversight with market‑based financing and partnership opportunities. This organizational framework supports the corporation’s long‑term strategy of expanding offshore capacity while adhering to China’s energy policy objectives.
