Seismic Imaging Using Lateral Adaptive Windows

P176 Seismic Imaging Using Lateral Adaptive Windows O. Pedersen* (Norwegian University of Science & Technology) S. Brandsberg-Dahl (BP America) & B. Ursin (Norwegian University of Science & Technology) SUMMARY We present a migration method using one-way propagators and lateral adaptive windows for handling the large velocity contrasts associated with salt-sediment interfaces. Using the adaptive windowing we can handle the large perturbations locally in a similar fashion as the Beamlet propagator hence limiting the impact of the errors on the global wavefield. We illustrate the performance of our method by applying it to synthetic data from the SEG/EAGE salt model. EAGE
