Directional resistivity measurements for azimuthal proximity detection of bed boundaries

An azimuthally tunable resistivity measurement tool comprising transmitter coils and receiver coils, wherein at least some of the transmitter coils or receiver coils are skewed and oriented in differing azimuthal directions, is disclosed. The transmitter coils transmit radio-frequency signals that p...
