Characterization of Fractured Reservoirs Using a Combination of Downhole Pressure and Self-Potential Transient Data
Figure 1
Results from the MINC double-porosity model. (a) Changes in pressure and SP at a point ~5 m away from the injection well (open hole) during injection test for fractured medium (after [8]). The pressure and SP changes for the equivalent porous medium are shown by broken curves. (b) Plot of the ratio of SP change to pressure change converted from the pressure and SP changes shown in (a).
