A simulation Study of Simultaneous Acid Gas EOR and CO2 Storage at Apache's Zama F Pool

Abstract This simulation study evaluates ways for maximizing incremental oil recovery (IOR) and CO2 storage capacity for a current simultaneous enhanced oil recovery (EOR) and CO2 storage project at the Zama oil field F Pool situated in northwestern Alberta, Canada. The results clearly indicate the viability of formation water extraction for increasing storage capacity in a closed geological structure. An approximately fivefold increase in CO2 storage capacity was observed, if current EOR is coupled with bottom water extraction. IOR of 22.1% in the next 20 years can be achieved, which is 5% more than continuing current EOR without bottom water extraction.
