The formation resistivity factor, ''F'', describes the tortuosity of the conductivity paths (pore space) in the rock. It can be determined in The saturation exponent, ''n'', describes how the tortuosity of the conductive paths in the formation increases as the water saturation

Where n is the saturation exponent, m is the cementation factor, a is the tortuosity, Rt is the measured formation resistivity in ohm-m, and S_w is th
