3D Multi-Arrival Kirchhoff vs. Wave Equation Migration - SEG/EAGE Salt Model Case Study

A-42 3D MULTI-ARRIVAL KIRCHHOFF VS. WAVE EQUATION MIGRATION - SEG/EAGE SALT MODEL CASE STUDY G. LAMBARE 1 B. DUQUET 2 and S. XU 1 3 1 Abstract In the context of the SEG/EAGE Salt model experiment we compare results obtained by 3D multi-arrival preserved amplitude ray based migration with those obtained by 3D wave equation migration. The same dataset is used but both preprocessing and velocity model differ (for Kirchhoff migration some smoothing had to be applied to the exact velocity model). By the end the better quality of images obtained using wave equation migration with the exact velocity model
