Characterization of Fractured Reservoirs Using a Combination of Downhole Pressure and Self-Potential Transient Data

Figure 3

The ratio of SP change to pressure change as a function of time (after [10]). Results from the reservoir model, for (a) open hole homogeneous case “open” and (b) open hole with a skin-zone case “open (skin)”; (c) Result from the equivalent MINC double-porosity model “open (MINC).”
