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

<table>Changes in SP in KF-3 (observation well) for three repeated KF-1 valve operations. Ratio of SP change to pressure change is also shown on the right. Both of ΔSP and ΔSP/Δ<i>P</i> are fairly reproducible.</table>
