L-14 PRESERVED AMPLITUDE DEPTH IMAGING – APPLICATION TO AN OBC LINE (MAHOGANY) Abstract 1 We present a first application of our 2D elastic prestack depth processing sequence to an OBC line recorded on the Mahogany field. This sequence is based on ray tracing in smooth velocity models and oriented towards amplitude preservation. Common Image Gathers (CIG) in the angle domain are computed by P-P and P-S migration/inversion using a Vp velocity macro-model obtained by stereotomography and a Vs velocity macro-model deduced from the Vp model by iterative pre-stack depth migrations. Introduction Ocean Bottom Seismology provides an opportunity to improve reservoir
