Abstract
An induction log is constructed in a sonde and has at least one or more transmitter coils and at least one or more receiver coils. The sonde supports a power supply and telemetry equipment along with transmitter and receiver apparatus for the coils. The transmitter coils require current levels as much as 1 amperes while the receive signals form output signals which are merely a fraction of a microvolt. The feedpipe array is preferably a feedpipe adapted to be centered in the axial lengthwise portion of the sonde and is further provided with a plurality of openings to enable leads for the coils to be connected. The feedpipe array is formed with a set of multiple steel tubes which are collectively assembled as a bundle on the interior of a copper sleeve.
