China National Offshore Oil Corporation (CNOOC) has discovered an oil and gas well in ultra-deep volcanic formations in central Bohai, offshore China, more than 5,000m below the seabed. According to the company, the well is situated next to the Bozhong Sag, said to be the largest hydrocarbon-rich sag in the Bohai region. The drilling reached […]
CNOOC Limited has drilled and discovered a high-yield volcanic oil and gas well in ultra-deep formations over 5,000 meters deep in Bohai, marking a major breakthrough in ultra-deep natural gas exploration offshore China. The well is located in central Bohai, adjacent to the Bozhong Sag, the largest hydrocarbon-rich sag in Bohai. It encountered a cumulative total […]
CNOOC Ltd. brought nine new projects on stream in the first three quarters of 2026, and its net production reached 593.7 MMboe, up 2.7% year-on-year and a record for the period. Net production from China rose 1.9% to 408.5 MMboe, mainly on contributions from projects including Kenli 10-2. Overseas net production rose 4.3% to 185.1 […]
CNOOC Limited produced a record 398.7 MMboe in the first half of 2026, up 3.7% year over year, as new offshore projects and exploration gains supported production growth in China and overseas.
ABB has been awarded a contract to modernize automation and safety control systems on the Buzzard offshore platform, supporting continued operations at one of the UK’s largest producing oil fields in the North Sea.
China’s top offshore crude oil and natural gas producer, CNOOC, on Wednesday announced the launch of full production from phase one development of the Kenli 10-2 oilfield in the south Bohai Sea.
“CNOOC Ltd. has adopted an innovative combined development approach of ‘conventional water injection + steam huff and puff + steam flooding’, providing strong technical support for the efficient utilization of oil reserves”, it added. “The project’s platform integrates both conventional cold production and thermal recovery systems, and is equipped with over 240 sets of key equipment.
Previously in 2025 CNOOC Ltd. announced three startups in the Bohai Sea and three in the South China Sea. The Bohai Sea projects are the Caofeidian 6-4 oilfield adjustment, phase 2 of the Luda 5-2 North field and the Bozhong 26-6 field. The South China Sea projects are Wenchang 19-1 oilfield phase 2, the Dongfang 29-1 field and the Panyu 11-12/10-1/10-2 Oilfield Adjustment Joint Development Project.
For 2025, the company lowered its production outlook and said it would keep capital expenditure at 2024 levels, but going forward, it said there were more record-breaking plans in production for the next two years. In 2025, the capital expenditure for exploration in China will mainly be directed to sustain crude oil reserves while expanding natural gas reserves, led by the construction of the three trillion-cubic-meters-level gas regions, CNOOC said in January, as it continues to follow China’s directive to state majors to boost domestic oil and gas reserves and supply.
The main production facility is a new drilling and production platform, which leverages the adjacent existing facilities for development. CNOOC added that 25 development wells are planned to be commissioned, including 18 production wells and seven gas injection wells.
