USE OF ELECTRODES AND MULTI-FREQUENCY FOCUSING TO CORRECT ECCENTRICITY AND MISALIGNMENT EFFECTS ON TRANSVERSAL INDUCTION MEASUREMENTS

摘要

A multicomponent induction logging tool uses a nonconducting mandrel. A central conducting member including wires that electrically connect at least one of the antennas to another of the antennas. Electrodes disposed about the transmitter antenna form a conductive path through a borehole fluid to the central conducting member.
