Apparatus and method for wellbore resistivity imaging using capacitive coupling

1. Field of the Invention An apparatus for obtaining resistivity images of a borehole includes an array of measure electrodes separated from a pad or the body of the instrument by a focusing electrode. The focusing electrode is maintained at a slightly higher potential than the measure electrodes. T...
