CNOOC Ltd. introduced Thursday an oil and gasoline discovery within the Weizhou 10-5 discipline, marking a “breakthrough” within the exploration of Paleozoic buried hills within the Beibu Gulf of the South China Sea.
Drilled to a complete depth of about 4,840 meters (15,879.27 ft) in an space with 37 meters of common water depth, exploration effectively WZ10-5-1Sa confirmed a pay zone of 283 meters. Throughout testing the effectively produced round 13.2 million cubic ft of pure gasoline and roughly 800 barrels of crude oil per day.
“It marks a serious breakthrough in pure gasoline exploration within the granite buried hills within the Beibu Gulf Basin”, the state-backed firm mentioned in an internet assertion, utilizing the native title for the Gulf of Tonkin.

Xu Changgui, chief geologist of CNOOC Ltd., commented, “The Weixinan Sag within the Beibu Gulf Basin is among the most explored sags offshore China”.
“Lately, the Firm has been researching on the reservoir formation theories of the complicated buried hills and the related applied sciences wanted”, Xu mentioned. “The breakthrough within the exploration of Paleozoic granite buried hills reveals the huge exploration prospects of the buried hills within the Beibu Gulf Basin. It’s going to additionally present steering for exploration in comparable fields offshore China”.
Chief government Zhou Xinhuai mentioned, “Lately, the Firm has made giant and medium-sized oil and gasoline discoveries in varied varieties of buried hills offshore China, which have been additional increasing the Firm’s oil and gasoline useful resource base”.
“The invention within the Beibu Gulf Basin will assist to stabilize power provide and repeatedly contribute to the financial and social improvement”, Zhou added.
Final month CNOOC Ltd., majority-owned by China Nationwide Offshore Oil Corp. (CNOOC), mentioned manufacturing had began within the globe’s largest buried metamorphic hill oilfield.
Producing gentle crude, Bozhong 26-6 is predicted to succeed in 22,300 barrels of oil equal a day in peak manufacturing this 12 months. The sector, which has a median water depth of about 20 meters, holds over 200 million cubic meters (7.06 billion cubic ft) of confirmed oil and gasoline in place, in keeping with CNOOC Ltd.
“Benefiting from the appliance of standardized engineering, it took solely three years from the invention of the oilfield to manufacturing, realizing the fast conversion of reserves to manufacturing”, it mentioned in a press launch February 7.
“As one of many demonstration CCUS [carbon capture, utilization and storage] initiatives of the Firm in Bohai, it adopts superior expertise to seize and separate the related carbon dioxide from crude oil extraction and reinject again into the formation to drive the oil, thereby growing manufacturing whereas decreasing emissions”.
CNOOC Ltd., the sphere’s sole developer, expects the CCUS part to bury about 1.5 million metric tons of carbon dioxide all through Bozhong 26-6’s life cycle.
The corporate, which claims to be China’s high offshore producer of petroleum and pure gasoline, eyes 33 improvement wells at Bozhong 26-6. Twenty-two of those are for manufacturing, 10 for gasoline injection and one for water entry.
The manufacturing services embody a brand new central processing platform and an unmanned wellhead platform.
“The profitable graduation of manufacturing of Bozhong 26-6 Oilfield Growth Venture (Section I) marks a brand new stage for the Firm within the improvement of offshore deep play difficult buried hill oil and gasoline reservoirs in addition to the development of the Bohai CCUS base”, mentioned CNOOC Ltd. president Yan Hongtao.
“It bolsters the Firm’s power provide capability and low-carbon improvement within the Beijing-Tianjin-Hebei and Bohai Rim areas”.
