China's first offshore carbon storage demonstration project has stored more than 20 million cubic meters of carbon since June 1 this year, according to China National Offshore Oil Corporation.
The project serves the Enping 15-1 oil platform in Shenzhen, South China's Guangdong Province and is expected to contribute to green and low-carbon development of the oilfield with an annual storage capacity of 150 million cu m.
The Enping 15-1 oil platform is the largest offshore crude oil production platform in Asia and the center of the oil field cluster. The oil field cluster has a peak daily production of more than 7,000 metric tons.
The carbon dioxide released during oil development is captured and processed into supercritical status and reinjected into the deep saline aquifer at a point 800 meters below the seabed and about three kilometers from the platform.
The head of the project said that the project's recent storage of more than 20 million cu m of carbon dioxide marked a significant breakthrough in carbon dioxide storage, and laid a technical foundation for future endeavors in the field.
