Wavefield imaging and tomography with the energy norm

This research explores wavefield imaging and tomography using the energy norm. High-resolution images are built with least-squares migration, and the conventional and new recovery methods are compared in the final iteration. Wavefield tomography is constrained using petrophysical information to obtain a true model without artifacts.
