Mechanism of Forming Low Resistivity in Shale Reservoirs

Figure 3

Resistivity of shale sample verified by test and numerical simulation: (a) core sample S5, (b) lamination in parallel with the current direction, and (c) lamination vertical to the current direction. (a) The shale sample S5 was selected for experimental testing [59]. (a) Shows the axial lamination of the sample. (b) The numerically simulated value of resistivity in the parallel lamination was 67.39 Ω·m. (c) That in the vertical lamination was 108.70 Ω·m. The numerical simulation results are in good agreement with the measured core results.
