Abstract:
An example method may include computing a database for an ideal representation of a galvanic tool, and determining internal coupling impedance between at least one monitor electrode of the galvanic tool and a reference. Voltage and current measurements from the galvanic tool positioned within a formation may be received. A formation resistivity from the voltage and current measurements may be calculated based, at least in part, on the database and the determined internal coupling impedances.
