Smooth hydrophone spectrum dips and extend measurement frequency range

Abstract

Methods and systems herein may be configured to utilize a downhole tool comprising: a transmitter configured to transmit an acoustic signal into at least part of a conduit string, wherein the transmitter is a first downhole element. In addition, receiver configured to measure an incoming signal from at least part of the conduit string, wherein the receiver is the first downhole element or a second downhole element. Further, disposing a downhole tool into a wellbore, wherein the downhole tool and transmitting an acoustic signal into at least part of a conduit string with the transmitter; and receiving the incoming signal from at least part of a conduit string with the receiver.
