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 11):
A system for processing a measured ultrasonic response waveform to determine a value indicative of whether a sealing medium acoustic impedance is within a designated range, the system comprising:\n an ultrasonic inspection tool that transmits an ultrasonic signal toward the well casing from within the well casing, the ultrasonic inspection tool comprising an ultrasonic transducer that generates a measured response waveform resulting from the transmitted ultrasonic signal; an output device; a processor; a tangible memory storing non-transient instructions executable by the processor to cause the processor to:\n process a measured response waveform resulting from an ultrasonic signal transmitted toward the well casing from within the well casing to determine an arrival time for a first reflection from the well casing; \n generate 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; \n identify a best-fit simulated response waveform from the plurality of simulated response waveforms that best matches the measured response waveform; \n determine, based on the identified best-fit simulated response waveform, the value indicative of whether the idling medium acoustic impedance is within the designated range; and \n output, via the output device, the value indicative of whether a sealing medium acoustic impedance is within the designated range for display to a user of the system.
