1. A system for calculating a formation shear-wave slowness comprising:
a borehole sonic logging tool comprising:
a transmitter comprising one or more elements disposed on the borehole sonic logging tool, wherein the transmitter is configured to transmit a first mode into a borehole; and
one or more receivers disposed on the borehole sonic logging tool, wherein the one or more receivers are configured to detect a second mode that one or more lobes than is a higher order than the first mode; and
an information handling system configured to apply a multimode frequency semblance to the second mode to form a dispersion log and calculate the formation shear-wave slowness from the second mode based at least in part on the dispersion log.
