Abstract
System and methods of generating calibrated downhole images of a subterranean formation () surrounding a wellbore (). The method involves placing a pad at a distance from a highly conductive surface and measuring a current between return electrodes of the pad and the highly conductive surface. The current may be used to determine a theoretic impedance of the current path, and impedance amplitude and impedance phase may be calibrated using theoretical impedance phase and theoretical impedance amplitude. Multiple standoff calibrations and temperature variation calibrations may also be used.
