Abstract
A method and system for determining the azimuth position and distance of a reflector or subterranean reflecting surface of a formation bed outside a borehole. A monopole transmitter may be used with a monopole/dipole receiver pair, or a monopole transmitter and a dipole transmitter pair may be used with a monopole receiver in accordance with the invention to determine the azimuth position and distance of the reflector. Azimuth resolution is improved through use of multiple receiver elements at equal radius about the longitudinal axis of a borehole tool, or through mathematical rotation of receiver elements.
