China's deep-sea oil and gas industry has become an important growth point

Several sets of data recently released in China's offshore oil sector indicate that deep-sea oil and gas hold significant potential:

Firstly, in 2025, the oil and gas production of "Shenhai No.1", the largest offshore gas field in China, exceeded 4.5 million tons of oil equivalent, comparable to the production scale of medium-sized onshore oil fields. China's deep-sea gas field production, operation, and maintenance technology has reached the world's advanced level.

Secondly, by 2025, the cumulative production of oil and gas from the offshore gas fields around Hainan Island, including "Shenhai No.1", will exceed 10 million tons of oil equivalent, doubling the production achieved at the end of the 13th Five-Year Plan period. Among them, deep-sea fields will account for more than 90% of the newly added oil and gas production in the region.

Thirdly, in 2025, the cumulative production of oil and gas equivalent in Bohai Oilfield, the largest offshore oilfield in China, exceeded 40 million tons, hitting a record high. Bohai Oilfield currently boasts over 60 operational oil and gas fields and more than 200 production facilities, with a cumulative production of over 600 million tons of crude oil.

According to the "China Marine Energy Development Report 2025" recently released by the Energy Economics Research Institute of China National Offshore Oil Corporation (CNOOC), China's marine oil production in 2025 is expected to reach approximately 68 million tons, an increase of about 2.5 million tons year-on-year, accounting for about 80% of the country's total oil production increase.

Li Jinsong, General Manager of CNOOC Lingshui-Yacheng Operating Company, introduced that "Shenhai No.1" produces 15 million cubic meters of natural gas and over 1,600 tons of condensate oil daily. A portion of the condensate oil is stored in the storage tanks located on the four columns of the platform, and once it reaches a certain volume, it is exported via shuttle tankers. This is also one of the three world-first technologies employed in the "Shenhai No.1" energy station. In 2025, the annual production of natural gas from the gas field reached 5 billion cubic meters for the first time, surpassing the peak capacity designed for the project.

In the future, CNOOC plans to widely promote and apply the production, operation, and maintenance technology system developed during the development and construction of "Shenhai No.1", to facilitate the further exploration of other deep-sea oil and gas structures in China.
