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

Figure 11

Electrical resistivity distribution around wells KF-1 and KF-3 (after [11]). Also shown are traces of major fractures, directions of core fractures, and locations of fluid feed points for KF-1 (e.g., [12]). Locations of KF-1 electrodes (nos. 5, 6, 8, and 10) showing typical fractured rock behavior in Figures 9 and 10 are denoted by yellow-filled asterisks, and those of KF-3 electrodes (nos. 18, 20) showing increasing trend are shown by white-filled asterisks. Locations of electrodes showing almost constant ΔSP/ΔP with time are shown by circles.
