P064 Summary IMAGING DEEP REFLECTORS: COMBINATION OF MCS AND WIDE-ANGLE DATA FOR A BETTER ESTIMATION OF THE VELOCITY MACRO-MODEL W. AGUDELO   A.RIBODETTI   S. 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
