Abstract: Apparatus and method are disclosed for determining properties of subsurface formations surrounding a borehole by induction logging. The properties which can be determined include the formation dip angle and dip azimuth angle. Indications of formation anisotropy can also be obtained. An array of individually energizable transmitter coils is provided, preferably including three coils having mutually orthogonal axes. Electronic transmitter steering circuitry is provided for controlling the energizing means to electronically steer the direction of the magnetic moment resulting from the magnetic field components generated by the transmitter coils. An array of receiver coils is also provided along with receiver processing circuitry for processing signals induced in the receiver coils. The array of receiver coils preferably includes three receiver coils having mutually orthogonal axes.
