Model for Environmentally and Economically Sound Linked Energy Systems
Kansas Geological Survey
Open-file Report 2002-6
Plans are to inject 0.4 hydrocarbon pore volume (0.8 BCF) of CO2 followed by a post-CO2 waterflood. Oil recovery is expected to be 60 to 120 MBO. The purpose of the demonstration is to determine the technical and economic feasibility of using CO2 miscible flooding to recover residual and bypassed oil in the Pennsylvanian L-KC in central Kansas. There have been no miscible CO2 floods in Kansas primarily due to the distance to the sources for CO2.
2.4 MMBO have been produced from the L-KC on the Colliver and Carter leases. Waterflood operations recovered more than 100% of primary production of the 38o API gravity oil from the solution gas drive reservoir.

|1998-99||CO2 EOR feasibility study conducted by University of Kansas (KGS and TORP), and Shell CO2 Company (now Kinder Morgan CO2 Co. L.P.). Submitted grant proposal (1999) to DOE.|
|2000-01||DOE grant awarded for CO2 EOR and work begun. Data gathering, reservoir characterization, drill and core CO2 injection well, additional resource assessment reservoir simulation, and technology transfer.|
|2001||Well injection testing and further reservoir simulation. U.S. Energy Partners ethanol plant completed and full capacity production began in November.|
|2002||Co-gen plant start-up in March. Final decision on how to proceed with EOR pilot, finish wellbore upgrades and testing, and install surface facilities, repressure reservoir to 1250 psi (presently 600-800 psi), and begin CO2 injection.|
