ABSTRACT:
A compact magnetic sensor is described that is capable of use in pad-mounted applications and field-focusing applications. A downhole induction tool is described with a compact induction sensor having electromagnetic transmitters wound on a longitudinal core member of a C-clamp shaped transmitter core. The downhole induction tool is suitable for transmitting magnetic excitation fields in multiple directions, both parallel and transverse to the downhole induction tool's longitudinal axis, with minimal susceptibility to errors associated with parasitic eddy currents induced in the metal components surrounding the transmitter and receiver coils. The horizontal (transverse) members of the C-clamp shaped transmitter core can be rotated to orient a magnetic excitation flux path passing between the horizontal (transverse) members and through a downhole formation. The horizontal members can be replicated on a single longitudinal member to shape the magnetic excitation flux path.
