P-wave AVO section: Color is CP; wiggle trace is near offset stack. (AVO Gradient AVO Intercept)/2 display of line 1 and line 2, spliced at the line tiepoint. Azimuthal dependence of the AVO response is evident at the Z and MB markers. At the line tie, line 1, left, shows a negative AVO response (blue) at the Z and MB reflectors, while line 2, right, shows a positive response (red-yellow) for these two reflectors.
