In order to find CO2 storage site for the first full-chain offshore CCUS project in Guangdong Province, we examined 16 producing oil fields in the Pearl River Mouth Basin offshore Guangdong. At first, we eliminated from consideration the fields having good hydrocarbon potential that will not be depleted in the next 10 years. Then the CO2-EOR potential was analyzed based on simple comparison with West Texas and UK continental shelf. Finally the remaining fields were screened and ranked with a scoring table based on published data on production status, trap, reservoir and caprock geology, and potential for infrastructure reuse. On this basis three fields, the HZ21-1, HZ32-3, and XJ24-3 were selected as candidate sites. Their advantages and disadvantages or knowledge gaps for CO2 storage were discussed. Suggestions for further work to fulfil the knowledge gaps in order to make final selection were proposed.
