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

<div>Response of multifrequency dielectric permittivity scanner in a borehole: (a) channel 1, (b) channel 2, (c) channel 3, and (d) channel 4, vs. water volume fraction color coded with shale volume. The frequency increases from channel 1 to channel 4.</div>
