Estimation of Water Saturation in Shale Formation Using In Situ Multifrequency Dielectric Permittivity

Figure 8

(a) Model-fitting results where black dash line is the optimized Archie’s parameter which can replicate the dielectric permittivity log (red dash line). (b) Water saturation calculated by using the optimized Archie’s parameter in red solid line. The optimization of Archie’s parameter provides the correction level of water saturation.
