ABSTRACT:
An induction logging tool having concentric transmitter and receiver antennas can be used to make measurements of earth formations at frequencies up to 500 MHz. The antennas may be mounted on the mandrel of a bottomhole assembly for MWD applications, or may be pad mounted for wireline applications. Litz winding is used in the coils to minimize eddy current losses. The antennas may be formed on a flexible circuit board.
