On June 29, CNOOC announced that it had made a major discovery of Huizhou 26-6 in the eastern waters of the South China Sea, and it is expected to become the first large and medium-sized condensate oil and gas field in the shallow water area of the Pearl River Mouth Basin.
Huizhou 26-6 structure is located in Huizhou Sag, a depression in the Pearl River Mouth Basin in the east of the South China Sea, with an average water depth of 113 meters. The discovery well HZ26-6-1 completed a drilling depth of 4276 meters and encountered a thickness of about 422.2 meters. After testing, the well produced an average daily output of 2020 barrels of crude oil and approximately 15.36 million cubic feet of natural gas.
The successful exploration of oil and gas-bearing structures in Huizhou 26-6 is the company’s first exploration of a new field of paleo-buried mountains in the eastern South China Sea. It has achieved a commercial high-yield gas flow, marking the company’s significant exploration of the Paleogene and paleo-buried complex oil and gas reservoirs in the Pearl River Mouth Basin. The breakthrough shows the huge prospects for exploration in this field.
