In the field of velocity model building there has been a strong focus over the last years on full waveform inversion methods, and much less on ray-based tomographic approaches. Tomographic approaches, however, remain the standard model building tool

Tomography algorithms using gridded model description and ray tracing have made continuous progress in terms of resolution and efficiency. However one strong limitation is the difficulty to recover strong velocity contrasts encountered in presence of

The increasing usage of wave equation and reverse time migration has motivated investigations about new types of common images gathers. Several types of angle domain common image gathers have then been proposed. While they should have the same aspect

The superior imaging capabilities of wide azimuth (WAZ) are now well established. Processing such acquisitions rquires adaptation of the processing workflows and tools. For example the recorded azimuthal information must be kept and the tools should

Slope tomography allows estimating velocity models from locally coherent events. These events can be picked in the prestack depth or time migrated domains, and then de-migrated into the prestack time un-migrated domain, providing what we call kinemat
