CO2-EOR and storage design optimization

The results quantitatively describe the relations between the design parameters, reservoir properties, asset size, and the economic parameters. With appropriate economic conditions and fiscal incentives, specifically in the form of storage tax credit, coupled CO2-EOR and storage could be attractive for both the oilfield operators and the government. In addition, CO2-EOR and storage is not the ultimate solution to the industrial-scale CO2 storage requirements. A medium-size industrial capture and storage for 25 years through EOR requires an asset size greater than the current field-scale EOR operations in the USA. Finally, the reservoir properties significantly affect the economic benefits for both the oilfield operators and the government. The proposed workflow may serve as a screening tool to rank the EOR-storage candidates and prioritize the most promising prospects for both the oilfield operators and the government.
