... an anisotropic or fractured media, unlike compressional (P) waves, shear waves are characterized by having different polarization into fast and slow shear waves. Shear waves propagating in anisotropic medium are called inline (SV) and cross-line (SH) (Crampin, 1981; Alford, 1986). The SV-wave is polarized...

... Summary Following the groundbreaking work of Crampin (1985), Alford (1986), Lynn and Thomsen (1990) and Lewis et al (1991), it quickly became conventional wisdom in the industry that substantial shear-wave azimuthal anisotropy is nearly ubiquitous in the subsurface. Crampin and Zatsepin (1995...

... shear-wave phase-velocity surfaces touch and are analytically continuous (Crampin and Yedlin, 1981). There are three types of singularity, kiss, point and line singularities. The line singularity is where two surfaces intersect along a line about the symmetry axis of a TI medium (Crampin and Yedlin...
