Wushi 23-5, an environmentally friendly oilfield cluster in the Beibu Gulf, south China, was put into operation on Monday, according to its operator, China National Offshore Oil Corporation (CNOOC).

Comprising 46 production wells in the eastern waters of the Beibu Gulf, Wushi 23-5 can achieve a peak daily crude oil output of over 2,000 tonnes.

"From design and construction to production, the oilfield cluster adopts environmentally friendly and low-carbon technologies throughout the entire cycle. We have also achieved zero discharge and zero pollution for the water used in production," said Dai Yi, general manager of the Wushi oilfield operation company under CNOOC's Zhanjiang Branch.

"It is the first oilfield in the Beibu Gulf to be supplied with electricity from shore, reducing the annual offshore gas consumption by an amount equivalent to 20,000 tonnes of standard coal," Dai added.

The cluster also features a comprehensive production mode that encompasses oil and gas production, gathering, processing and sales. Its processing technology effectively converts associated natural gas into liquefied natural gas (LNG) and liquefied petroleum gas (LPG) for storage, loading, and transportation.

"Taking the development of the Wushi 23-5 oilfield cluster as an opportunity, we have promoted local green industries, including local fishing-photovoltaic complementary projects and the development of offshore wind resources," said Deng Yong, deputy general manager of the CNOOC Zhanjiang Branch. "This serves as a demonstration for the low-carbon transformation of offshore oil exploration and production."
