Abstract
A method for determining the electrical properties of a core sample having an initial saturation S, an initial true resistivity R, and a porosity ϕ, including the steps: preparing a brine having a resistivity R, flushing the core sample with the brine, determining a first true resistivity Rat a first saturation S, once the resistivity Rof the brine going into the core sample is the same as the resistivity Rof the brine going out of the core sample, determining a function R=f(S) describing the dependency of the true resistivity Rof the core sample and the saturation Sin the core sample, based on the initial saturation S, initial true resistivity R, first true resistivity R, and first saturation S, second true resistivity R, and first saturation S, determining the resistivity Rof the fully saturated core sample by estimating the function R=f(S) to full saturation of the core sample at S=100%, determining a resistivity index at the S, S, Sdetermining a saturation exponent n using linear regression of the log-log plot of Ivs. S.
