Effect of Structure on Wide Azimuth Acquisition and Processing

C012 Effect of Structure on Wide Azimuth Acquisition and Processing B.J. VerWest* (CGGVeritas) D. Lin (CGGVeritas) Z. Meng (CGGVeritas) & S. Neal (Chevron USA) SUMMARY This model study shows that narrow azimuth acquisition may be adequate for structures which are oriented dip to the acquisition direction but strike components are not well imaged. Wide azimuth acquisition with sufficient cross line offset gives improved results compared to narrow azimuth acquisition for both dip and strike components since this method is actually “directionless”. Also 3D SRME on narrow azimuth data shot dip gives a good image but narrow azimuth strike data does
