Electrode-based tool measurement corrections based on measured leakage currents

Abstract

An example system includes an electrode-based tool for deployment in a downhole environment, where the electrode-based tool having a plurality of current electrodes, at least one voltage monitoring electrode, at least one return electrode. The electrode-based tool also includes electronics to measure leakage current between at least one of the plurality of current electrodes and the at least one return electrode as current from at least one of the plurality of current electrodes is injected into the downhole environment and flows to the at least one return electrode. The system also includes at least one processor configured to derive a corrected downhole environment parameter based at least in part on the measured leakage current.
