Although generalizations can be unfair and controversial, it is helpful to divide interest in seismic anisotropy into one of two broad categories: situations where anisotropy is an inconvenience and must be removed or corrected for in an analysis, and applications where anisotropy can be exploited to improve an interpretation. For those requiring a sub-surface image, especially using wide-azimuth and far-offset seismic data, anisotropic effects must be considered in the processing flow to remove anomalies caused by directional variations in the seismic velocity.
