2 Results of Layer Reservoir Simulation Study Schaben Field, Ness County, Kansas 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 program (under contract DE-FC- 9BC987). The Schaben demonstration site consists of 7 contiguous acres within the Schaben field and spreads over Sections 9, 9,, and in Range W/Township 9S and over Sections,,,, and in Range W/Township 9S (Figure A, 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 BOAST simulator. Results of this study available over the Internet at and This initial study was followed by second simulation study (using DOE s BOAST simulator) where the reservoir was described by two layers with an underlying bottom aquifer forming the third layer. Background of the simulation study A sedimentologic and diagenetic study, using cores from the Schaben field, revealed that the reservoir-strata were deposited on a ramp. The basal stratum (MO) consists of normal to somewhat restricted marine strata. The MO stratum has an abundance of echinodermrich facies with a diverse fauna. The upper strata (M) was mainly made up of sponge spicule-rich facies that contained silicified original evaporite minerals. An internal unconformity, a subaerial exposure event, separates MO strata from M. The post Mississippian unconformity caps the entire sequence. The best reservoir was found to be the sponge spicule-rich wackestone/packstone facies (SWP) with replaced evaporites. Echinoderm-rich wacke-packstones (EWPG) were also found to form locally important reservoir facies. However, EWPG facies that are dominant in the MO unit are not likely to result in favorable reservoirs because processes associated with M unit lead to the occlusion of its porosity. The reservoir volume constructed for the simulation study was therefore made up of two layers, layer conforming to M strata and layer conforming to the MO strata. Within the simulation input-data, the major difference in petrophysical properties for layers and was in their respective net to gross ratio. The ratio-value assigned to layer was.8 while that for layer was.. During the course of history matching, the net to gross

3 ratio for some of the wells had to be changed from this initial assumption to obtain a reasonable match with the production/pressure history. Input data Figure A shows the study-area (Schaben field) that was simulated in BOAST along with the location of the wells. The grid cell dimensions used was ft by ft. Table shows the cell addresses related to each well within the study area and also the corresponding name given for each well to display the output results from the simulation. Appendix A contains plots showing the distribution of various gridded parameters that were used in this simulation study. Figures A and A show the gross isopachs maps of layer and layer. Figures A and A show the final net isopach maps obtained at the end of the history matching. In the absence of additional data, the effective porosity for both M and MO was assumed to be the same (Figure A). The distribution of horizontal permeability-feet for layers M and MO is shown in Figures A and A7, while the vertical permeability for these two layers are displayed in Figures A8 and A9. The distribution of initial reservoir pressure (9) is shown in Figure A. Initial oil saturation (9) within the effective porosity of M and MO is shown in Figures A. The PVT data, relative permeability and capillary pressure data and the well data entered into the input file were the same as used in the two layer simulation study in BOAST. Results of history matching Appendix B shows the results of the history match that was obtained at each well. The oil production at each well was entered into the simulator for the first years and the simulator calculated the corresponding water production during this time and also calculated the corresponding bottom hole pressure. This calculated bottom hole pressure, at the end of the th year, was input for each well for the simulator to calculate both the oil and water production during the remaining period of the production life of each well (till December 99). Current fluid level data was available for most wells and was used to calculate the current bottom hole pressure. In the absence of a recorded history of pressure measurements, the bottom pressure was varied between that at the end of the th year and the current pressure to attaining a history match at each well. Appendix C consists of maps showing the distribution of remaining potential in Schaben field as of 99. Figures C and C show the residual oil saturation (December 99), obtained from the simulation output after the history match at the well level, in M and MO. Figure C maps the remaining areas with the best potential, as of December 99, for infill drilling in the Schaben field. The areas shown in color on the map have remaining oil saturation of at least % and a net pay greater than feet. Based on the remaining potential map, the various operators of the Schaben field drilled infill wells between 99 and 998.

4 Results of performance prediction of infill wells Appendix C compares the performance, as predicted by the simulation model, of the infill wells with the production data recorded at each of the infill well during the first few months of their lives.
