C023 Imaging Methods in Complex Overburden A. Guitton* (3DGeo Inc.) A. Valenciano (Stanford University) F. Ortigosa (Repsol YPF) & B. Kaelin (3DGeo Inc.) SUMMARY Three migration techniques suited for complex overburden are presented. The first one is a wave-equation method based on a one-way propagator. The second one is a two-way method that utilizes one-way propagators for the wavefield extrapolation downward and upward. The third one is based on the solution of two-way wave equation also know as Reverse Time Migration. The selection of a migration algorithm should be based on practical and geophysical considerations. The complexity of the subsurface
