Imaging Deep Reflectors – Combination of MCS and Wide-Angle Data for a Better Estimation of the Velocity Macro-Model

OPERTO   A.GAILLER     UMR Géosciences Azur 6526 IRD-CNRS-UNSA BP 48 06235 Villefranche-sur-mer In recent years there have been an increasing interest for a better imaging of deep structures in different contexts such as oil reservoir characterization nuclear residuals stock and natural hazard assessment. We present here a strategy to improve deep reflectors imaging by a ray-based prestack depth migration through a better constrained velocity macro-model estimation for deep zones. The approach is based
