Feasibility of CCUS to CO2-EOR in Alberta
Carbon Capture Utilization and Storage (CCUS) is a critical mitigation technology in the fight to reduce global emissions and CO2 utilization through Enhanced Oil Recovery (EOR) is an influential economic driver. This study presents a method and techno-economic model that considers reservoir suitability for CO2-EOR and price conditions at which CO2 projects become feasible and applies financial levers to identify cumulative CO2 storage potential and incremental oil recovery in Alberta. The results demonstrate that CO2-EOR in Alberta has the potential to store between 131Mt and 1.3Gt of CO2 at a minimum field-delivered CO2 price of $60/tonne. There are, however, a limited number of economic pool-clusters with material CO2 storage potential. Financial levers can bridge the gap in CO2 supply price and reduce economic risks for CO2-EOR projects to promote the further deployment of CCUS to CO2-EOR in Alberta.
