Abstract:
Systems and methods process a measured ultrasonic response waveform to determine a well casing thickness and an acoustic impedance of a sealing medium surrounding the well casing. An array of simulated response waveforms corresponding to a set of candidate acoustic impedances for the sealing medium surrounding the well casing and a set of candidate well casing thicknesses is generated. A simulated response waveform from the array of simulated response waveforms is identified that best matches the measured response waveform so as to determine the sealing medium acoustic impedance.

Claim (Index 15):
The system of  claim 13 , wherein the instructions are executable by the processor to:\n calculate a differential signal between the measured response waveform and the best-fit simulated response waveform; calculate a corrected transducer impulse response for the ultrasonic transducer by correcting the transducer impulse response based on the differential signal; generate a second-iteration plurality of simulated response waveforms based on the corrected transducer impulse response and corresponding to the arrival time, a second-iteration set of candidate acoustic impedances for the sealing medium surrounding the well casing, a second-iteration set of candidate well casing thicknesses within a range that includes the approximate thickness of the well casing, a second-iteration set of candidate annulus thicknesses within a range that includes an approximate thickness of the annulus, and a second-iteration set of candidate properties for at least one interface between the sealing medium and the ground formation surrounding the annulus; and identify a second-iteration best-fit simulated response waveform from the second-iteration plurality of simulated response waveforms that best matches the measured response waveform, wherein the value indicative of whether the sealing medium acoustic impedance is within the designated range is determined based on the identified second-iteration best-fit simulated response waveform.
