Abstract Because it is necessary to focus on differences in regional oil reservoirs and determine the priority of CCUS‐EOR (Carbon capture, utilization, storage‐enhanced recovery) deployment under China's net‐zero CO 2 emission target, systematic evaluations sequestration capacity major basins are needed considering geofluid properties—carbon place (CSCIP)—where ‘in place’ indicates actual geological formation conditions underground, e.g., temperature pressure. Therefore, physical properties geofluids at different depths with geologic temperatures pressure considered for evaluation place, including shallow (800–2000 m), medium (2000–3500 deep (3500–4500 m) ultra‐deep (4500–8000 depth intervals. A modified model four grading levels proposed, combining P‐V‐T equations state (EOS) Carbon Sequestration Leadership Forum (CSLF), theoretical, effective, practical, CSCIP, which more consistent make ranking CSCIP basins. Then, 29 China was evaluated based petroleum resources results Ministry Natural Resources (MNRC) during 13 th Five‐Year Plan period. According results, suggestions prospective regions given as follows: fields Songliao Basin Northeast China, shallow–medium Bohai Bay East Zhungeer West Ordos Central China; all potential areas onshore In addition, offshore basins, Sea Pearl River Mouth have sequestration.
