CNOOC starts production at secondary development project

CNOOC Ltd. has started production from the Liuhua 11-1/4-1 oilfield secondary development project 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 305 m. The main production infrastructure includes a new deepwater jacket platform (Haiji-2) and a cylindrical FPSO (Haikui-1). A total of 32 development wells are to be commissioned. The heavy crude oil project is expected to achieve peak production of about 17,900 boe/d in 2026.

Production marks “the first oilfield in Asia to be developed with the 'Deepwater Jacket Platform + Cylindrical FPSO' mode,” said Zhou Xinhuai, chief executive officer, president, CNOOC Ltd.

“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,” and provides a solution “for the efficient development of similar deepwater oil and gas fields,” he continued.

CNOOC Ltd. is operator of the project with 100% interest.
