The Schaben field is located in Ness County, Kansas. A detailed reservoir characterization and simulation study was carried out in the northern part of the field under a project funded by DOE's Class 2 program (under contract DE-FC22-93BC14987). The Schaben demonstration site consists of 1720 contiguous acres within the Schaben field and spreads over Sections 19, 29, 30, 31 and 32 in Range 21W/Township 19S and over Sections 23, 24, 25, 26, 35 and 36 in Range 22W/Township 19S (Figure A1, Appendix A). The objective of this study was to improve reservoir performance of mature oil fields, located in shallow shelf carbonate reservoirs of the Midcontinent, by demonstrating the application of cost-effective tools and techniques to characterize and simulate the reservoir.
The initial study included analyses and integration of geologic data, production data, and petrophysical log and core data to develop a reservoir geomodel. This geomodel formed the basis for a two-layer reservoir simulation study using DOE's BOAST3 simulator. Results of this study available over the Internet at http://www.kgs.ku.edu/Class2/index.html and http://www.kgs.ku.edu/DPA/Schaben/schabenMain.html. This initial study was followed by second simulation study (using DOE's BOAST4 simulator) where the reservoir was described by two layers with an underlying bottom aquifer forming the third layer.
