Abstract | In aspects, an apparatus for use in a wellbore for determining a property of an earth formation is provided. The apparatus, in one embodiment, may include a tool body including a transmitter configured to induce electromagnetic waves in an earth formation, a receiver configured to provide signals responsive to the induced electromagnetic waves, a conductive member between the transmitter and the receiver extending radially from the tool body and configured to reduce propagation of eddy currents between the transmitter and the receiver when the tool body is in a wellbore and a processor configured to process the signals provided by the receiver to determine the property of the earth formation. |
