Improved Oil Recovery in Mississippian Carbonate Reservoirs of Kansas -- Near Term -- Class 2, by Lee C. Gerhard, Timothy R. Carr, G. Paul Willhite, Dana Adkins-Heljeson, Scott Beaty, Saibal Bhattacharya, Evan Franseen, Paul Gerlach, Willard Guy, John Hopkins and W. Lynn Watney. Section 2.3.4 and appendices D - F were prepared by Rodney Reynolds, Shapour Vossoughi, and G. Paul Willhite.


This annual report describes progress during the second year of the project entitled "Improved Oil Recovery in Mississippian Carbonate Reservoirs in Kansas". This project funded under the Department of Energy’s Class 2 program targets improving the reservoir performance of mature oil fields located in shallow shelf carbonate reservoirs. The focus of this project is development and demonstration of cost-effective reservoir description and management technologies to extend the economic life of mature reservoirs in Kansas and the mid-continent. As part of the project, several tools and techniques for reservoir description and management were developed, modified and demonstrated. These include: 1) a new approach to subsurface visualization using electric logs ("Pseudoseismic"); 2) a low-cost easy-to-use spreadsheet log analysis software (PfEFFER); and 3) an extension of the BOAST-3 computer program for full field reservoir simulation. The world-wide-web was used to provide rapid and flexible dissemination of the project results through the Internet.
