| Abstract | An “EKP-postprocessor” computational tool was developed several years ago to calculate space/time distributions of electrokinetic potentials resulting from histories of underground conditions (pressure, temperature, liquid-phase saturation, concentration of dissolved species, etc.) computed by unsteady multi-dimensional geothermal reservoir simulations (Ishido and Pritchett, 1996). Since that time, the postprocessor has been applied to various geothermal reservoir engineering problems. The results of numerical simulation calculations to study the possibility of characterizing fractured reservoirs using a combination of pressure and self-potential transient data are presented in this paper. |
