CNOOC achieved high yield well in Beibu Gulf

Wushi 16-5 structure is located in Wushi Sag, Beibu Gulf, with an average water depth of approximately 25 m. The appraisal well WS16-5-4 was drilled and completed at a depth of 4185 m, encountering a total of 65 m oil pay zones. The well was tested to produce over 1000 m³/d of oil, the first well of such productivity in Wushi Sag. The discovery is expected to become a medium-sized oilfield. By far, the total proved oil in-place of Wushi oilfields has exceeded 100 million m³.

Mr. Xu Changgui, Chief Geologist of the Company, said, “CNOOC Limited has been pushing forward the rolling exploration in the surrounding area of Wushi oilfields for years with leading technologies. The successful well proves the promising exploration potential in the mature area of Wushi Sag, which will guide our rolling exploration activities in offshore China.”
