B12 WAVE EQUATION DEPTH MIGRATION IN NORTH AFRICA DEEP WATERS Summary 1 This paper focuses on recent advances in wave equation migration algorithms and their implications for deep water seismic exploration offshore Egypt. The analysis of 2D Kirchhoff pre-stack depth migrated (PSDM) data reveals complex structures that are likely to benefit from wave equation migration. Ray tracing and impulse responses are used to assess these benefits. Introduction Seismic imaging methods can be divided into two broad categories. Kirchhoff methods rely on ray tracing to estimate traveltimes through a velocity model. These traveltimes are then used to reposition data to its
