【CCUS】Phase 1 Pilot Test of CCUS at CNOOC Hainan Fushan Gas Field

Thread Content

For the oil and petrochemical industry, CCUS involves injecting the captured carbon dioxide into oil wells to extract oil while sequestering the carbon dioxide, thereby achieving the dual benefits of reducing emissions and increasing production. As Hainan’s only onshore oil and gas exploration and production company, Fushan Oilfield completed and put into operation Phase 1 of its CCUS pilot project as early as November 2018. This project resulted in an increase of 7,500 tons in oil production, with 82,200 tons of carbon dioxide being sequestered – an amount equivalent to the annual carbon emissions from over 30,000 cars. While achieving carbon dioxide sequestration, we can increase our oil and gas recovery rate from 30% to 45%, resulting in highly significant economic and environmental benefits. At present, the Fushan oil field has developed a complete set of technologies for the utilization and sequestration of carbon dioxide. The second phase of the CCUS project, with an investment of 62.46 million yuan, involves the construction of a facility for the separation, capture, and liquefaction of carbon dioxide at a rate of 150,000 cubic meters per day, with an annual sequestration capacity of 100,000 tons. The main construction work for this project has been largely completed, and equipment testing is currently in progress; operations are scheduled to begin in early September this year.
