1. A method for identifying guided waves in a measurement set, comprising:
disposing an acoustic logging tool into a wellbore;
taking one or more measurements with the acoustic logging tool in the wellbore to form a data set which comprises one or more guided waves;
identify a speed of the one or more guided waves from the data set;
identifying a fluid phase interface using the speed of the one or more guided waves;
estimating an acoustic velocity of a wellbore fluid using a database based on at least the speed of one or more guided waves; and
interpreting the fluid phase based at least in part on the acoustic velocity of the wellbore fluid.
