More Information
Summary:A system herein includes one or more processors to determine asymmetric compensation measurements from at least one receiver antenna pair and at least one transmitter antenna pair on a tool body in an underground formation. The asymmetric compensation measurements are to be used with symmetric compensation measurements from the plurality of antenna pairs. The asymmetric compensation measurements are associated with signals from individual transmitter antennas that are at asymmetric or unequal distances from individual receiver antennas that receive a version of the signals. The individual receiver antennas are part of the at least one receiver antenna pair having symmetrically located receiver antennas with respect to a midpoint of the tool body and the individual transmitter antennas are part of the at least one transmitter antenna pair having symmetrically located transmitter antennas with respect to a midpoint of the tool body.
