Velocity analysis for transversely isotropic media

T Alkhalifah, I Tsvankin - Geophysics, 1995 - library.seg.org
The main difficulty in extending seismic processing to anisotropic media is the recovery of
anisotropic velocity fields from surface reflection data. We suggest carrying out velocity …

Velocity analysis using nonhyperbolic moveout in transversely isotropic media

T Alkhalifah - Geophysics, 1997 - library.seg.org
