CO2 recycling accounting and EOR operation scheduling to assist in storage capacity assessment at a U.S. gulf coast depleted reservoir

► A protocol to estimate fine-scale distribution of stored CO2 is developed. ► It was applied to the East and West compartments at Cranfield. ► We investigated factors impacting capacity in EOR-then-storage vs pure storage. ► When a spill point is present, CO2 capacity is a strong function of operations.
