The project is located in shallow waters and is tied back to existing infrastructure at the Huixi Oilfields. Development includes a new unmanned wellhead platform and a total of 10 development wells, which are scheduled to be commissioned.
CNOOC expects the project to reach peak production of about 18,000 barrels of oil equivalent per day in 2026. Output will consist primarily of light crude oil.
The Xijiang 24-7 platform is China’s first unmanned offshore platform designed for high-temperature fluid cooling and export. The company said the platform’s temperature control system is intended to reduce thermal stress on subsea pipelines and support stable, continuous production.
CNOOC Limited holds a 100% working interest in the development and is the project operator.
