CNOOC commissions China's first offshore CCS demonstration project

CNOOC Ltd. has commissioned China's first offshore carbon capture and storage (CCS) demonstration project, the operator said in a release May 31.

The project is supplementary to development of Enping 15-1 oil field. Enping 15-1, in the Pearl River Mouth basin about 190 km southwest of Hong Kong in average water depth of 80 m, holds large levels of CO₂, the company said.

The CCS module can capture, process, and inject CO₂ produced from the field into the saline water layer at a depth of about 800 m under the seabed. The project can store over 1.5 million tons of CO₂, the operator said.
