BEIJING: China’s first comprehensive environmentally friendly oilfield cluster, Wushi 23-5, was put into operation in South China’s Guangdong province on Monday, its operator China National Offshore Oil Co (CNOOC) says.

Comprising 43 development wells, including 28 production wells and 15 water injection wells, the project will have peak production of around 18,100 barrels of oil equivalent per day that is expected to be achieved in 2026, CNOOC said.

It is the first time that oil and gas have been transported from two kms under the seabed to Leizhou Peninsula in Guangdong province.

This is a new model in the green development of offshore oilfields in China that is also expected to minimise the effect on the marine environment, said the company.

CNOOC said it achieved zero discharge and zero pollution during the process of water treatment after oilfield production in the cluster.

It is also the first oilfield in the Beibu Gulf to be supplied with electricity from shore, through two 35 kilovolt lines of China Southern Power Grid that will reduce the annual offshore gas combustion equivalent to 20,000 tonnes of standard coal, cutting carbon dioxide emissions by 44,000 tonnes, it said.
