Abstract
The main difficulty in extending seismic processing to anisotropic media is the recovery of anisotropic velocity fields from surface reflection data. As shown by Tsvankin and Thomsen (1995), P-wave moveout from horizontal reflectors is insufficient to obtain the parameters of transversely isotropic media with a vertical symmetry axis (VTI), even if long spreads (twice the reflector depth) are used.
