<p>A pressure-balanced acoustic-signal-receiving apparatus and methods therefor. The apparatus may comprise a first housing, a first actuator, a second housing, and a second actuator. The first housing may comprise a fluid chamber, a passage connecting a first and second portion of the fluid chamber, a tubular-contact assembly, an isolating member within the fluid chamber and coupled to the assembly, an acoustic-signal receiver within the isolating member and coupled to the assembly, and a communication member coupled to the receiver. A method for receiving an acoustic signal generated within a wellbore may comprise receiving the acoustic signal with a tubular-contact assembly, sensing the acoustic signal with an acoustic-signal receiver positioned within a fluid chamber and coupled to the assembly, equilibrating fluid pressures in the first and second portions of the fluid chamber, and transmitting information generated by the acoustic-signal receiver through a communication member.</p> |
