CNOOC Limited has commenced production at the Liuhua Oilfield Secondary Development Project located in the eastern South China Sea.

The project consists of two oilfields, Liuhua 11-1 and Liuhua 4-1, with an average water depth of approximately 305 meters. The main production facilities include a new deepwater jacket platform “Haiji-2” and a cylindrical FPSO “Haikui-1”.

A total of 32 development wells are to be commissioned, according to CNOOC. It holds 100% operating interest in this project.

The company stated in a press release on Thursday that the project is anticipated to achieve a peak production of approximately 17,900 barrels of oil equivalent per day (boe/d) in 2026.

The oil property is heavy crude.

“It is the first oilfield in Asia to be developed with the ‘Deepwater Jacket Platform + Cylindrical FPSO’ mode. The Company has overcome various technological challenges to complete the project,” said Zhou Xinhuai, CEO and President of the CNOOC.

“While revitalizing the deepwater oilfields with original oil in place over 100 million tons, the new mode has substantially reduced the construction and production costs. It provides a Chinese solution for the efficient development of similar deepwater oil and gas fields,” he added.
