Advanced PSDM WEM and RTM Imaging – in the Pre-Caspian Region

We demonstrated the application of migration by wavefield continuation to a field survey from the Pre-Caspian region. The dataset has challenging geology that requires advanced imaging algorithms to handle the complex wave propagation. The algorithms were designed for media with tilted transverse isotropy (TTI). We have illustrated that both WEM and RTM provide good uplift in image quality compared to Kirchhoff as they are able to handle the multi pathing caused by complex salt bodies. We showed that RTM yields good images without dip limitations whereas the one-way solution is a good cost-effective alternative for high frequency, high resolution, subsalt imaging.
