Abstract
An acoustic isolator and methods to the same. The acoustic isolator may comprise a body, one or more annular chambers formed inside the body of the acoustic isolator and positioned along a longitudinal axis of the acoustic isolator, an annular groove formed on an outer surface of the body of the acoustic isolator, and a passage disposed between the one or more annular chambers and the annular groove. The method may comprise transmitting an acoustic wave from a transmitter disposed on an acoustic logging tool into a subterranean formation, receiving an acoustic signal from the subterranean formation with a receiver disposed on the acoustic logging tool, and attenuating a second acoustic wave that moves between the transmitter and the receiver and through an acoustic isolator.
