Abstract
Systems and methods for communicating information acoustically through a plug in a temporarily or permanently abandoned well. The disclosed embodiments use an acoustically transmissive well plug, where an acoustic transmitter coupled to a measurement tool below the plug is coupled to the plug In a manner that is intended to maximize the coupling of the generated acoustic signals to the plug. These signals are then transmitted through the acoustically transmissive plug to an acoustic receiver that is coupled to the upper end of the plug. The acoustic receiver converts the acoustic signals to another form if necessary and forwards the signals to equipment at the surface of the well, or to intermediate transceivers that can relay the signals to the surface.
