Abstract
A method for identifying guided waves in a measurement set. The method may comprise disposing an acoustic logging tool into a wellbore, performing a measurement operation with the acoustic logging too in the wellbore to form a data set which comprises one or more guided waves, measuring a speed of the one or more guided waves, and identifying a fluid phase interface using the speed of the one or more guided waves. The method may further comprise estimating an acoustic velocity of a wellbore fluid using a database and interpreting the fluid phase based at least in part on the acoustic velocity of the wellbore fluid.
