A Practical Approach to Automated PP Angle Tomography

The use of the differential semblance misfit function on common image point gathers in the angle domain, lends itself to an automated tomographic approach through a gradient based search of the model space. The common image point gathers are created by the AVA-corrected or incomplete generalized Radon transform. We present a real data example of PP scattering events and an approach to regularize the optimization by respecting geological features.
