HONG KONG, Dec. 21, 2025 — CNOOC Limited (the “Company”, SEHK: 00883 (HKD Counter) and 80883 (RMB Counter), SSE: 600938) today announces that the Xijiang Oilfields 24 Block Development Project has begun production.
The project is located in the shallow waters of the Pearl River Mouth Basin. The development of the project mainly makes use of the adjacent existing facilities of the Huixi Oilfields, with the addition of a new unmanned wellhead platform. Ten development wells are planned to be put into operation. The project is expected to reach a plateau production of approximately 18,000 barrels of oil equivalent per day in 2026. The oil is light crude.
The new Xijiang 24-7 platform is China’s first unmanned offshore platform for high-temperature fluid cooling and export. The temperature control system lessens the impact of high temperatures on subsea pipelines, thereby ensuring stable and continuous production.
CNOOC Limited holds 100% interest in this project and is the operator.
