Field Demonstration of Carbon Dioxide Miscible Flooding in the Lansing-kansas City Formation, Central Kansas

Year: 2005

Type: report

Abstract: A pilot carbon dioxide miscible flood was initiated in the Lansing Kansas City C formation in the Hall Gurney Field, Russell County, Kansas.The reservoir zone is an oomoldic carbonate located at a depth of about 2900 feet.The pilot consists of one carbon dioxide injection well and two production wells on about 10 acre spacing.Continuous carbon dioxide injection began on December 2, 2003.By the end of June 2005, 16.19 MM lb of carbon dioxide were injected into the pilot area.Carbon dioxide injection rates averaged about 227 MCFD during the last six months of the project.Carbon dioxide is produced in both production wells.The GOR has remained within the range of 4000-5000 for most the last six months.Wells in the pilot area produced 100% water at the beginning of the flood.Oil production began in February 2004, increasing to an average of about 3.78 B/D for the six month period between January 1 and June 30, 2005.Cumulative oil production was 1494 bbls.Neither well has experienced increased oil production rates expected from the arrival of the oil bank generated by carbon dioxide injection.Injection was converted to water on June 21, 2005 to reduce operating costs to a breakeven level with the expectation that sufficient carbon dioxide has been injected to displace the oil bank to the production wells by water injection.
