Abstract
The disclosure is concerned with a tool and method for imaging a formation through a substantially non-conductive medium. The tool includes one or more injection electrodes for injecting current through the substantially non-conductive medium and into the formation. The tool further includes one or more return electrodes for receiving current from the substantially non-conductive medium, the formation, or both. The tool also includes circuitry for determining a complex impedance based on the received current, determining a phase angle of the complex impedance, and determining a component of the complex impedance that is orthogonal to the phase angle.
