It is responsible for the cooperative exploitation of offshore oil and natural gas resources in Chinese waters. It is China's largest offshore oil and gas producer. The company was established in 1982 with a registered capital of 94.90 billion yuan and is headquartered in Beijing. It currently has 51,000 employees. Since its establishment, CNOOC has maintained a good development trend. It has developed from a pure upstream company solely engaged in oil and gas extraction to a comprehensive enterprise group with a prominent main business and a complete industrial chain. It has formed six industrial sectors with benign interactions such as oil and gas exploration and development, professional technical services, chemical fertilizer refining, natural gas and power generation, financial services, comprehensive services and new energy. In recent years, through the successful implementation of strategies such as reform and reorganization, capital operation, overseas mergers and acquisitions, and upstream and downstream integration, the company has achieved leapfrog development, and its comprehensive competitive strength has been continuously enhanced. Gradually, it has established the image of a lean and efficient international oil company.
