Pilot Scale CO2 EOR in Mississippian Carbonate Reservoir at Wellington Field in South-Central Kansas

CO2 EOR effectiveness and CO2 retention and storage efficiencies in application to Mississippian carbonate reservoirs in Kansas were successfully tested with this small scale field project. Total of 1,101 truckloads, 19,803 metric tons, average of 120 tonnes per day were delivered over the course of injection that lasted from January 9 to June 21, 2016. Current incremental average oil production rate is 34 bbls/day and a total of incremental 6,300 bbls of oil were produced as a result of CO2 injection. Only 12% of injected CO2 was produced back currently (3 months since injection stopped CO2). Published by Elsevier Ltd.
