(WO) – CNOOC Limited announced that the Liuhua 11-1/4-1 oil development offshore China has commenced production.

The project is located in eastern South China Sea and consists of two oil fields, Liuhua 11-1 and Liuhua 4-1, with an average water depth of approximately 305 m. The main production facilities include a new deep water jacket platform Haiji-2 and a cylindrical FPSO Haikui-1.

A total of 32 development wells are to be commissioned. The project is expected to achieve a peak production of approximately 17,900 bopd in 2026. The oil property is heavy crude.

Mr. Zhou Xinhuai, CEO and President of the company, said, “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. While revitalizing the deep water 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 deep water oil and gas fields.”

CNOOC Limited holds 100% interest in this project and is the operator.
