ABSTRACT:
Resistivities are measured for a plurality of subsections of a porous rock following a fluid injection that alters the fluid saturation throughout the porous rock. The measured subsection resistivites are compared to identify an equilibrium in the altered fluid saturation throughout the porous rock when there is a fixed relationship between the measured subsection resistivities. Following the detection of fluid saturation equilibrium, the resistivity of the porous rock is measured.
