Full-wave-equation depth migration using multiple reflections | CU Experts

Overview

We present a migration method in the temporal frequency domain that can propagate both downgoing and upgoing waves. The method can handle arbitrary velocity model, and we demonstrate its ability to image overturned events and steep reflectors. Our algorithm has the advantage of migrating the data sequentially in depth and frequency, leading to significant advantages compared to Reverse Time Migration when combined with migration velocity analysis. We also show that the method can easily generate offset and angle gathers.
