China's largest offshore oilfield, the Bohai Oilfield, has produced over 40 million tonnes of oil equivalent in 2025, setting a historical record, the China National Offshore Oil Corporation (CNOOC) said Sunday.
As the country's leading offshore oilfield in both output and scale, this record output will provide robust support for national energy security and contribute to high-quality economic and social development, according to CNOOC.
The Bohai Oilfield currently manages more than 60 oil and gas fields and over 200 production facilities. Over the past five years, the oilfield has experienced an annual production increase of 5 percent, contributing nearly 40 percent of the national increase in crude oil output. This growth positions the Bohai Oilfield as a key player in enhancing domestic oil and gas reserves and production capacity.
According to Zhang Zongchao, production manager at CNOOC's Tianjin branch, the oilfield this year has focused on enhancing production capacity, rapidly bringing multiple key projects.
"This year, we have rapidly advanced the construction and production of several key projects, including the Kenli 10-2 and Bozhong 26-6 fields and other 100 million-ton fields. Currently, the oilfield is producing over 100,000 tonnes of oil and gas per day, accounting for more than 60 percent of China's total offshore oil and gas output. Our annual production of oil and gas has surpassed 40 million tonnes," he said.
With a cumulative crude oil output exceeding 600 million tonnes, the Bohai Oilfield has solidified its status as the largest integrated oil and gas production base in China, encompassing exploration, development, engineering construction, and production operations.
