Beijing: China's first deepwater oilfield, the Liuhua Oilfield, has seen the full commencement of its secondary development project, as announced by the China National Offshore Oil Corporation on Sunday.
According to Emirates News Agency, this achievement signifies a significant advancement in China's capacity to develop complex deepwater oil and gas reservoirs. The Liuhua Oilfield, situated in the Pearl River Mouth Basin, holds the title of China's largest offshore reef limestone oilfield when considering proven geological reserves. Since its initial launch in 1996, the oilfield has successfully extracted over 20 million tonnes of crude oil.
Despite this substantial output, an estimated 140 million tonnes of reserves remain untapped within the seabed strata, prompting the need for secondary development to harness this potential. The project includes two oilfields, Liuhua 11-1 and Liuhua 4-1, located in waters with an average depth of about 305 meters, and it involves 32 production wells.
Since the first set of wells started operating in September 2024, the daily crude oil production has reached a peak of 3,900 tonnes.
