Abstract
A microresistivity logging tool and method for making microresistivity measurements, of which the tool includes a logging tool body having a longitudinal axis, a transmitter coil deployed in the tool body, the transmitter coil including an electrical conductor wound about a magnetically permeable core, the electrical conductor being connected to a high frequency alternating current generator deployed in the tool body, a receiver coil deployed in the tool body and including an electrical conductor wound about a magnetically permeable core, the electrical conductor being connected to a high frequency alternating voltage sensor deployed in the tool body. The transmitter and receiver coils each define a coil axis that is substantially perpendicular to the longitudinal axis of the tool body. The receiver coil and the transmitter coil are coaxial and deployed in the same plane.
