The Chinese state-owned oil and gas company China National Offshore Oil Corporation (CNOOC) has launched production at its Bozhong 26-6 offshore oil field, putting to use the carbon capture, storage and utilization (CCUS) technology installed at the site.
Located in the Bohai Bay, the Bozhong 26-6 oil field is considered as one of the world’s largest metamorphic buried hill oil fields with a cumulative proven oil and gas in-place of over 200 million cubic meters.
The oil field facility is also home to one of CNOOC’s CCUS demonstration projects, equipped with a sophisticated technology that has the ability to capture and separates CO2 from crude oil extraction, reinjecting the captured carbon dioxide back into the formation to drive the oil and providing a solution for CO2 emissions.
According to CNOOC estimates, over the complete project lifecycle, the Bohai CCUS base will be able to bury approximately 1.5 million tons of carbon dioxide.
CNOOC president Yan Hongtao commented that this advancement marks a new stage for the company in the development of offshore deep play complicated buried hill oil and gas reservoirs, as well as for the construction of the Bohai CCUS base.
He stated, “It bolsters the company’s energy supply capacity and low-carbon development in the Beijing-Tianjin-Hebei and Bohai Rim regions.”
The oil production facilities on the offshore site include a new processing platform and an unmanned wellhead platform.

CNOOC intends to commission a total of 33 development wells, 22 of which will be production wells, 10 gas injection wells and one well for a water source. The company also shares that this project experienced a rapid development, taking only three years from the oil field discovery to launch production at the site.
During 2025, the Bozhong 26-6 offshore oil field project is expected to reach a peak production of approximately 22,300 barrels of oil equivalent per day, producing light crude oil from this location.
