T Migration and Velocity Analysis - Application to Real Data from the Red Sea

A-06 W-MIGRATION AND VELOCITY ANALYSIS – APPLICATION TO REAL DATA FROM THE RED SEA TARIQ A ALKHALIFAH 1 Institute for Astronomy and Geophysical Research KACST PO Box 6086 11442 Riyadh Saudi Arabia SUMMARY Imaging the pre-alt reflections for data acquired from the coastal region of the Red Sea is a task that requires prestack migration velocity analysis. Conventional poststack time processing lacks the lateralinhomogeneity capability needed for such a problem. Prestack migration velocity analysis in the vertical time domain reduces the velocity-depth ambiguity usually hampering the performance of prestack depthmigration velocity analysis. In prestack τ migration velocity analysis we keep
