Lessons Learned from Small Scale Field Test Demonstrating CO2 EOR and Geologic Storage at Wellington Field in Southern Kansas

CO2 EOR and geologic storage demonstration project performed under DOE NETL grant (DE-FE0006821) initially included one site characterization phase and two operational phases: CO2 EOR in Mississippian carbonate reservoir and saline aquafer CO2 geologic storage demonstration. Site characterization and CO2 EOR pilot were successfully executed and geologic storage demonstration component could not progress due to permitting limitations and induced seismicity concerns.
