Improved oil recovery in fluvial dominated deltaic reservoirs of Kansas -- Near-term. Quarterly progress report, October 1--December 31, 1997

The objective of this project is to address waterflood problems of the type found in Morrow sandstone reservoirs in southwestern Kansas and in Cherokee Group reservoirs in southeastern Kansas. Two demonstration sites operated by different independent oil operators are involved in this project. The Stewart Field is located in Finney County, Kansas and is operated by PetroSantander, Inc. The Nelson Lease is located in Allen County, Kansas, in the N.E. Savonburg Field and is operated by James E. Russell Petroleum, Inc. General topics to be addressed are (1) reservoir management and performance evaluation, (2) waterflood optimization, and (3) the demonstration of recovery processes involving off-the-shelf technologies which can be used to enhance waterflood recovery, increase reserves, and reduce the abandonment rate of these reservoir types. Progress in the Stewart field project is described for the following tasks: design/construct waterflood plant; design/construct injection system; design/construct battery consolidation and gathering system; waterflood operations and reservoir management; and technology transfer. Progress in the Savonburg field project is described for the following tasks: profile modification treatments; pattern changes and wellbore cleanup; reservoir development (polymer flooding); and technology transfer
