Some form of anisotropy is always expected.
Anisotropy, or the variation of wave propagation as a function of direction, can be caused by a number of factors. These include grain alignment, stress and fracture sets.
An understanding of anisotropy is not only necessary for imaging but also for insights into the mechanical characteristics of geological formations, all of which aid seismic interpretation.
Our full-azimuth processing solutions are on call to keep your gathers nice, flat and wobble-free.
