Abstract (en)
[origin: WO2013102761A2] A method and apparatus for generating, propagating, encoding, decoding, modulating and detecting acoustic signals in a well borehole that comprises a signal generator located at a first location for generating an acoustic source signal; a medium for the propagation the acoustic source signal to a second location and the propagation of the reflections and partial reflections of acoustic signals as it propagates through the medium; an apparatus to remove a detectable amount of energy from propagated acoustic signals; a controllable signal modulator for attenuating the transmitted acoustic source signal; and a receiver for receiving the modulated acoustic signals reflected, partially reflected or both by at least one reflector respectively located at one or more other locations.
