摘要

In the paper "A numerical investigation of the acoustic mode waves in a deviated borehole penetrating a transversely isotropic formation" by Liu et al.[1] numerical experiments are reported for a dipole sonic logging scenario with a deviated borehole penetrating a VTI anisotropic medium.In such a situation it is important to clearly define the meaning of group and phase velocities as this has led to much confusion in the literature as discussed by Miller,Horne and Walsh [2].
