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.
