CNOOC Ltd. introduced Monday the beginning of manufacturing on the Wenchang 19-1 Oilfield Part 2 Undertaking within the South China Sea and the Caofeidian 6-4 Oilfield Complete Adjustment Undertaking within the Bohai Sea.
The oil and fuel exploration and manufacturing firm, which claims to be the most important producer of oil and fuel offshore China, has now introduced six upstream start-ups in Chinese language waters this 12 months.
CNOOC Ltd., majority-owned by China Nationwide Offshore Oil Corp. (CNOOC), expects the second part of Wenchang 19-1 to achieve 12,000 barrels of oil equal a day (boed) in peak manufacturing 2027. The venture produces medium crude.

The Caofeidian 6-4 adjustment venture is anticipated to attain 11,000 boed in peak manufacturing 2026. The oil is gentle crude.
“The design idea of clever oil and fuel fields have been [sic] used within the two new tasks”, CNOOC Ltd. stated in a press launch. “Among the procedures, equivalent to crude oil manufacturing, gear upkeep, and security administration, have been upgraded with clever applied sciences, to reinforce the effectivity of hydrocarbon growth”.
Wenchang 19-1 part 2 makes use of a megawatt-level high-temperature flue fuel ORC energy era unit capable of produce as much as 24 million kilowatt hours of electrical energy. The unit can lower the venture’s carbon dioxide (CO2) emissions by about 23,000 metric tons a 12 months, based on CNOOC Ltd.
The Caofeidian 6-4 adjustment venture re-injects related fuel into the reservoir utilizing compressors, curbing the venture’s CO2 emissions by round 13,000 metric tons a 12 months, it stated.
Wenchang 19-1 part 2 sits in a median water depth of roughly 125 meters (410.1 toes) within the west of the Pearl River Mouth Basin. It has a brand new drilling and manufacturing platform but additionally makes use of adjoining present services. CNOOC Ltd. eyes 13 manufacturing wells.
The Caofeidian 6-4 adjustment venture, within the west of the Bohai Sea, has a median water depth of about 20 meters. The principle facility is a brand new manufacturing wellhead platform. It additionally makes use of present services. CNOOC Ltd. plans 25 wells: 22 for manufacturing and three for water injection.
It’s the sole developer in each tasks.
Beforehand in 2025 CNOOC Ltd. stated it has put onstream two tasks within the Bohai Sea and two within the South China Sea, all of that are solely owned by the corporate.

The South China Sea tasks are the Dongfang 29-1 discipline and the Panyu 11-12/10-1/10-2 Oilfield Adjustment Joint Growth Undertaking.
Luda 5-2 North part 2 may attain about 6,700 boed in peak manufacturing subsequent 12 months, it introduced February 21. Part 1 went on-line 2022 as the primary Chinese language oilfield to provide from super-heavy oil reservoirs by way of thermal restoration, based on CNOOC Ltd.
It stated of Luda 5-2 North part 2, “CNOOC Restricted made main technological breakthroughs on this venture and considerably enhanced the event effectivity of offshore tremendous heavy oil”.
“By means of optimized Jet Pump Injection-Manufacturing Know-how, the venture realized environment friendly and financial growth of heavy crude, which may additional improve the Firm’s vitality provide capability”, CNOOC Ltd. added.
Bozhong 26-6 may attain 22,300 boed in peak manufacturing this 12 months, it stated February 7 asserting the start-up of what it known as the globe’s largest buried metamorphic hill oilfield.
Bozhong 26-6, which has a median water depth of about 20 meters, holds over 200 million cubic meters (7.06 billion cubic toes) of confirmed oil and fuel in place, based on CNOOC Ltd.
It famous, “As one of many demonstration CCUS [carbon capture, utilization and storage] tasks of the Firm in Bohai, it adopts superior know-how 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 lowering emissions”. The CCUS element is anticipated to bury about 1.5 million metric tons of CO2 all through Bozhong 26-6’s life cycle.
“The profitable graduation of manufacturing of Bozhong 26-6 Oilfield Growth Undertaking (Part I) marks a brand new stage for the Firm within the growth of offshore deep play difficult buried hill oil and fuel reservoirs in addition to the development of the Bohai CCUS base”, commented CNOOC Ltd. president Yan Hongtao.
“It bolsters the Firm’s vitality provide capability and low-carbon growth within the Beijing-Tianjin-Hebei and Bohai Rim areas”.
Dongfang 29-1 may attain 38 million cubic toes a day in peak fuel manufacturing 2025, CNOOC Ltd. stated January 20.
Panyu 11-12/10-1/10-2 may attain 13,600 boed in peak manufacturing 2025, it stated January 2. The Panyu discipline has produced over 380 million barrels of petroleum since coming on-line 2003, based on CNOOC Ltd.
