Abstract
Systems and methods for determining a shear wave slowness may include emitting an emitted acoustic wave within a borehole from an acoustic tool. A return acoustic wave may be detected via one or more sensors. The return acoustic wave may be generated when the emitted acoustic wave interacts with a physical feature within the borehole. A signal may be generated that may be indicative of the return acoustic wave. The method may include evaluating the signal via a processor to determine a pseudo-Rayleigh mode slowness and calculating a shear wave slowness using an analytical relationship. The analytical relationship may include a mathematical correlation between the pseudo-Rayleigh mode slowness and the shear wave slowness. The analytical relationship may also include input parameters that are measured physical parameters of borehole properties.
