Abstract: Downhole equipment in a well includes an acoustic feature that emits an acoustic signal providing an indication of the operation of the downhole equipment. The downhole equipment is placed, above, below, or around a tubing string, or elsewhere in the well. The downhole equipment can include a flow control valve, a housing assembly, a sand screen assembly, or a base pipe. The acoustic feature can be a protrusion and notch that engage and generate the acoustic signal. Alternatively, a moving component such as a turbine can be included in the downhole equipment and can generate the acoustic signal when the component moves. Alternatively, the acoustic feature can be any means that emits a unique acoustic signal.
