Subsurface anisotropy from shear-wave splitting in zero of near-offset VSPs - case studies

Over recent years the Edinburgh Anisotropy Project has developed and tested display, processing, and interpretation techniques with the specific aim of enhancing (without distortion) and estimating the information contained in split shear-waves from multi-component seismic data. These techniques, incorporated into a shear-wave analysis package, permit an assessment of the vector seismic wavefield in terms of several characteristic parameters of shear-wave splitting.
