Claim 21:
22. A method for determining an integrity of a material, comprising:
placing an acoustic logging tool in a wellbore, wherein the acoustic logging tool comprises:
a transmitter on the acoustic logging tool to broadcast a pressure pulse; and
a receiver on the acoustic logging tool to record a reflected pressure pulse;

broadcasting the pressure pulse with the transmitter into a first material, wherein the pressure pulse reflects off an interface of the first material and a pipe string as the reflected pressure pulse;
recording the reflected pressure pulse with a receiver; and
determining 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 indices, wherein each index from the series of indices comprises one or more ray paths through a zone of interest, wherein an arrival time of each ray path is compared to a range of arrival times wherein the Quintero Wellbore Index for the zone of interest is determined by, QWI=(Arrival time of appropriate ray−Arrival time of theoretical ray with fast cement/Arrival time of theoretical ray if zone 100% filled with water−Arrival time of theoretical ray with fast cement).
