An electromagnetic logging tool includes a support configured for disposal
in a well; at least one antenna mounted on the support; and a plurality
of coils mounted on the support proximate the at least one antenna,
wherein the plurality of the coils are configured for selective
connection with the at least one antenna. A methods for balancing an
induction array on an electromagnetic logging tool includes measuring a
mutual coupling between a transmitter and a receiver on the
electromagnetic logging tool; and selectively connecting a subset of a
plurality of coils on the electromagnetic logging tool to the transmitter
or the receiver based on the measured mutual coupling.
