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.
