CNOOC Logs Four Offshore Discoveries and 16 Appraisals in First Half of 2026
CNOOC made four offshore discoveries and completed 16 successful appraisals in the first half of 2026, alongside three project start-ups offshore China, according to Offshore Magazine.
The discoveries were located in Bohai Bay and the South China Sea, and Offshore Magazine reported that they support China's ongoing efforts to increase domestic offshore oil and gas production.
Three developments came onstream offshore China during the period: the Penglai 19-3 Oilfield 1/2/3/8/9 Area Secondary Adjustment Project, the Weizhou 10-3 Oilfield West Area Development Project, and the Huizhou 25-8 Oilfield Comprehensive Adjustment Project, per the same report.
Outside its production portfolio, the company connected Haiyou Anlan, described by Offshore Magazine as China's first tension-leg floating wind power platform, to the grid. The platform should supply 54 million kWh of electricity per year to an oil field.
CNOOC also fully commissioned China's first offshore carbon capture and utilization project, according to Offshore Magazine.
The pairing of a floating wind platform feeding an offshore oil field with a first-of-its-kind offshore carbon capture and utilization installation places power supply and emissions handling inside the same upstream programme that produced the four discoveries and 16 appraisals.
