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 1):
A computer-implemented method of processing a measured ultrasonic response waveform to determine a value indicative of whether a sealing medium acoustic impedance is within a designated range, the method comprising:\n transmitting an ultrasonic signal from an ultrasonic inspection tool toward the well casing from within the well casing; generating, via an ultrasonic transducer, a measured response waveform resulting from the transmitted ultrasonic signal, wherein the ultrasonic inspection tool comprises the ultrasonic transducer; processing the measured response waveform to determine an arrival time for a first reflection from the well casing; generating a plurality of simulated response waveforms corresponding to the arrival time, a set of candidate acoustic impedances for the sealing medium in the annulus, a set of candidate well casing thicknesses, a set of candidate annulus thicknesses, and a set of candidate properties comprising acoustic impedances for one or more interfaces between the sealing medium and a ground formation surrounding the annulus; identifying a best-fit simulated response waveform from the plurality of simulated response waveforms that best matches the measured response waveform; determining, based on the identified best-fit simulated response waveform, the value indicative of whether the sealing medium acoustic impedance is within the designated range; and outputting the value indicative of whether a sealing medium acoustic impedance is within the designated range to a user via an output device.
