1. A well measurement system for determining integrity of a material comprising:
an acoustic logging tool, wherein the acoustic logging tool comprises:
at least one transmitter to broadcast a pressure pulse; and
at least one receiver to record the reflected pressure pulse; and
an information handling system, wherein the information handling system is configured to determine the integrity of the material using a Quintero Wellbore Index based at least in part on the reflected pressure pulse, wherein the Quintero Wellbore Index is a series of at least two indices, wherein each index from the series of at least two indices comprises one or more ray paths with one or more arrival times through a zone of interest, wherein the zone of interest is separated by a pipe string or a casing for each index from the series of at least two indices.
