Figure 8.19. Observations of shear wave velocity anisotropy from the dipole sonic logs in the pilot
hole and main hole. The direction of the sedimentary bedding planes is the mean strike determined
in the electrical conductivity image and the black bars in the middle plot indicate the orientation of
S Hmax in the pilot hole (after Boness and Zoback 2006).
