Miller (Kansas Geological Survey-University of Kansas) A.P. Byrnes (Kansas Geological Survey-University of Kansas) W.L. Watney (Kansas Geological Survey-University of Kansas) & E.K. Franseen (Kansas Geological Survey-University of Kansas) SUMMARY Time-lapse seismic was utilized to monitor carbon dioxide movement and aid reservoir modeling in an enhanced oil recovery/sequestration pilot study. The target interval was a 900-m deep 5-m thick oomoldic limestone. in the Hall-Gurney Field central Kansas USA. Fluid replacement modeling indicted
