CNOOC has announced that China’s first offshore large-sized independent deepwater gas field, the Lingshui 17-2 gas field, has commenced production.

The Lingshui 17-2 gas field is located in the northern sea of the Qiongdongnan Basin, with a water depth of approximately 1560 m. It is China's first large-sized deepwater discovery, with proven geological resources of natural gas exceeding 100 billion m3, made by independent exploration.

A new semi-submersible production platform has been built with condensate oil storage capacity and a mooring system, as well as a set of underwater production systems and subsea pipelines. A total of 11 production wells are planned. It is expected to reach peak production of 328 million ft3 of natural gas and 6751 bpd of condensate in 2022, with a 10-year stable production period. After the commencement of production, natural gas will be connected to the national gas pipeline network through submarine pipelines, and will become one of the important sources of stable natural gas supply for Guangdong-Hong Kong-Hainan area.

CNOOC holds a 100% interest in the Lingshui 17-2 gas field and acts as the operator.

Wang Dongjin, the Chairman of the company said: “Commencement of production in Lingshui 17-2 gas field indicates the company has taken a leap towards the 1500 m ultra-deepwater field, further releasing the company’s natural gas potential. In the future, CNOOC Limited will continue to enhance our exploration and development activities, strive to expand reserves and production, increase the proportion of green, low-carbon as well as clean energy, and hence to support the goal of carbon emission peak and carbon neutrality to be achieved at an early date.”
