Abstract
In some embodiments, an apparatus, system, and method may operate to transmit a current from an electrode at a first azimuthal location into a borehole wall in a geological formation, and to receive the first current at a second electrode at a second azimuthal location in the borehole wall. The first and second azimuthal locations are disposed approximately along the same longitudinal location of the borehole wall. The current may be adjusted to maintain a selected voltage profile between the electrodes at the first and second azimuthal locations, and the electrodes at the first and second azimuthal locations may be members of two different sets of azimuthally] differentiated electrodes. Additional apparatus, systems, and methods are disclosed.
