Abstract

In Subsection 3.5.8 normal moveout and dip moveout corrections were defined. It was shown that for stacking common mid point (CMP) gather data for a dipping reflector, the correct stacking velocity depends on the angle of dip of the reflector [Eq. (3.27) — renumbered as (11.1)] in the following form
$$ {t^2} = ({t_0} + \frac{{4{h^2}{{\cos }^2}\theta }}{{{V^2}}}) $$
(11.1)
It was further shown in Subsection 4.4.3 that for an anisotropic medium having direction dependent velocity, the stacking velocity is very sensitive to the angle of dip when the symmetry axis is perpendicular to the ground surface.
