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, ...
[ What is claimed is:] [1.] A method of determining an azimuth position of a subterranean reflecting surface of a formation bed outside a borehole, which comprises:generating a monopole acoustic waveform for transmission into said formation bed to produce a reflection waveform;receiving said reflection waveform with both a monopole receiver and a dipole receiver in a borehole tool;adding a monopole response of said monopole receiver to said reflection waveform and a dipole response of said dipole receiver to said reflection waveform to generate a monopol...
