Claim 13:
14. One or more tangible non-transitory computer-readable storage media storing computer-executable instructions for performing a computer process on a computing system, the computer process comprising:
obtaining an axial acoustic signal using an axial sensor deployed in a structure in a subterranean surface;
obtaining a radial acoustic signal using a radial sensor deployed in the structure;
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; and
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 at least partly on the radial acoustic signal;
determining if the portion of the structure is axially or radially homogenous by combining the axial log with the radial log.
