1. A method comprising:
disposing a bottom hole assembly (BHA) into a wellbore, wherein the BHA comprises:
at least two transmitter configured to transmit a pressure pulse; and
at least two receiver configured to record two or more waveforms;
performing a logging-while-drilling (LWD) operation in which the two or more waveforms are recorded with the at least two receiver;
transmitting the two or more waveforms to an information handling system;
removing two or more tool mode waveforms from the two or more waveforms to form an updated set of waveforms after two or more individual recordations of the two or more waveforms; and
forming differential phase time semblance map based at least in part on the updated set of waveforms.
