Abstract
An improved induction tool for evaluating formation resistivity. The tool provides electromagnetic transmitters and sensors suitable for transmitting and receiving magnetic fields in radial directions that are orthogonal to the 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. A magnetic lens is provided to select sensitivity to a desired reservoir formation property.
