Simulation of ionic transport for estimation of hydraulic conductivity by history matching electric log measurements with Modflow and MT3D

Abstract

It was found that the hydraulic conductivity (permeability) of a formation could be estimated by history matching the invasion of a known mud filtrate into a known water quality (resistivity) of an aquifer. A drilled well is modeled, varying permeability, in a reservoir simulator until the invasion parameters of a contaminant transport model matches the resistivity curves made on an electric well log for a given set of data.
