Abstract: In the past two years, China National Offshore Oil Corporation (CNOOC) has made great efforts in domestic offshore exploration, carried out "value exploration" with the goal of finding recoverable reserves, strengthened risk exploration, and actively explored new areas and new domains. The resulting achievements have been impressive. Through continuous research, a considerable number of updated geological understandings and technological breakthroughs have been achieved. Important exploration breakthroughs have been made in three domains: buried hill in the Bohai Bay Basin, the deep-water area in the Qiongdongnan Basin, and the Yangjiang sag in the Pearl River Mouth Basin. In the immediate future, CNOOC will continue to vigorously expand exploration efforts, extend research on exploration domains such as deep formations, deep water, high-temperature and high-pressure formations, further explore potential rich hydrocarbon generation sags, and expand exploration domains and directions.
