  • Anisotropic casing solids and fluids identification system and method using shear and flexural acoustic waves
    Patent number: 12180824
    Abstract: A system for evaluation of a sheathing behind a casing of a wellbore. One or more wave generators provide at least asymmetric lamb (AL) waves through a casing having an anisotropic property in a first mode of the system, and provide at least shear horizontal acoustic (SHA) waves through the casing in a second mode that is concurrent with the first mode. A receiver receives indications associated with the SHA waves and the AL waves. At least one processor determines a quality of the sheathing behind the casing based in part on the indications associated with the SHA waves and the AL waves.
    Type: Grant
