China National Offshore Oil Corporation (CNOOC) has commenced production from the Caofeidian 6-4 oil field located in the mid-west of Bohai offshore China.
Situated in an average water depth of 20m, the Caofeidian 6-4 oil field is anticipated to reach peak production capacity of about 15,000 barrels of crude oil per day in 2023.
The project involves the development of a total of 42 wells, comprising 12 water injection wells, 30 production wells, and water source wells.
CNOOC said that the project will utilise the existing processing facilities of Nanpu 35-2 oilfield and Qinhuangdao 32-6 oilfield. It involved the development of a new central platform.
In a press statement, CNOOC said: “Guided by the vision of green development, Caofeidian 6-4 oilfield will actively promote green and low-carbon production.
“With the introduction of onshore power engineering, it is estimated that about 16,000t of standard coal will be saved, and about 40,000t of carbon dioxide will be reduced annually.”
As an operator, CNOOC owns a 100% stake in Caofeidian 6-4 oilfield.
Last month, CNOOC announced a large-sized oil and gas discovery following the drilling of the discovery well BZ13-2-2 in Bozhong 13-2, Bohai Bay.
The Bozhong 13-2 structure is located in the south-western Ring of Bozhong Sag and in an average water depth of about 23.2m.
Upon drilling at a depth of 5,223m, the discovery well BZ13-2-2 encountered oil pay zones with a total thickness of approximately 346m.
The company tested the well, which produced an average of approximately 1,980 barrels of crude oil and 5.25 million cubic feet of natural gas per day.
