Abstract
A bi-directional acoustic telemetry system is presented for communicating data and/or control signals between a first modem and a second modem along tubing. The system includes a communication channel defined by the tubing, a transducer of the first modem, and a transducer of the second modem. The transducer of each modem are configured to transmit and receive data and/or control signals, and are further configured to electrically communicate with a power amplifier characterized by an output impedance Zs and a signal conditioning amplifier characterized by an input impedance Zr. The system also includes a reciprocal response along the communication channel between the output impedance Zs and the input impedance Zr.
