oa ThrustBelt Imaging Challenges – Learning from 3D Fullwave Modeling

Seismic image quality in foothills and thrust-belts with rugged topography is often very poor with conventional low-fold sparse 3D orthogonal surveys. The most often cited reason is the high-level of shotgenerated noise backscattered from near-surface heterogeneities and irregular topography. Consequently, many depth imaging projects in thrusted terrains have been disappointing.
