Claim 0:
1. A method for isolation detection in a wellbore, the method comprising:
obtaining an axial acoustic signal, the axial acoustic signal captured using an axial sensor deployed in a structure in a subterranean surface;
determining one or more velocities of one or more waveforms included in the axial acoustic signal;
separating the axial acoustic signal into a first wave region and a second wave region by applying velocity filtering to the one or more velocities;
generating an axial log indicating an axial symmetry of a portion of the structure based on at least one of the first wave region or the second wave region;
generating a radial log indicating a radial symmetry of the portion of the structure based on a radial acoustic signal; and
combining the axial log and the radial log to generate an isolation characterization for the portion of the structure.
