CNOOC Discovers Major Oilfield in Bohai Sea, Boosting Reserves by Over 100 Million Tons

CNOOC Achieves Landmark Oilfield Discovery in Bohai Sea

CNOOC Limited announces a groundbreaking discovery in the Qinhuangdao 29-6 oilfield, located in the central Bohai Sea. This significant find adds over 100 million tons of oil equivalent in-place, marking a pivotal moment for the company and the region. The discovery well, which reaches a depth of 1,688 meters, uncovers 66.7 meters of oil pay zones, yielding approximately 2,560 barrels of crude oil per day. The oilfield is situated within the shallow Neogene formations, particularly in the Minghuazhen Formation, recognized for its medium-heavy crude oil characteristics. This successful exploration effort highlights CNOOC's commitment to expanding its resource base in a mature exploration area.

Chief Geologist Xu Changgui emphasizes the significance of this discovery, which challenges conventional perceptions by identifying slope areas as viable sites for hydrocarbon accumulation. Traditionally viewed as pathways for oil migration, these regions are now recognized for their potential to hold substantial reserves. The Qinhuangdao 29-6 oilfield becomes the second one-hundred-million-ton-class lithological oilfield discovered in the Shijiutuo Uplift, underscoring the necessity for detailed exploration techniques in mature basins. Such findings not only bolster CNOOC's reserves but also affirm the importance of innovative research and technological advancements in hydrocarbon exploration.

CNOOC's commitment to exploring complex geological structures influenced by extensional-strike-slip faulting plays a crucial role in this discovery. The company aims to solidify its position in the oil and gas sector through continued exploration efforts, maximizing its output potential. As CNOOC enhances its exploration endeavors, the recent discovery at Qinhuangdao 29-6 stands as a testament to the company's strategic approach in navigating the challenges of resource extraction in mature fields.

In related news, CNOOC Limited continues to focus on technological innovation as a key driver for growth in its exploration activities. The company believes that advancements in research methodologies will enable it to unlock further potential in existing assets and uncover new reserves. This approach not only supports CNOOC's operational goals but also strengthens its competitive position in the global energy market.
