Abstract
A micro-resistivity caliper, in some embodiments, comprises a cylindrical body; multiple center electrodes, arranged circumferentially about the cylindrical body, to emit current into a borehole and toward a borehole wall; multiple focus electrodes to limit dispersion of the current emitted by the center electrodes, each of the focus electrodes surrounding a different center electrode; multiple return electrodes to receive the current emitted by the center electrodes, each of the return electrodes surrounding a different focus electrode; and one or more processors, coupled to the return electrodes, to determine one or more standoffs between the micro-resistivity caliper and the borehole wall based on the currents received from the multiple return electrodes.
