Reprocessing using a 3D velocity model obtained from passive Seismic Tomography (Click here to see the brochure)

The region encountered severe seismic penetration problems due to heavily weathered surface limestone layers, high topographic reliefs and evaporite barriers. The conventional seismic 2D seismic lines were of very bad quality due to inaccurate velocity models used for the data processing. After reprocessing the conventional seismic data using the 3D velocities obtained from the PST survey (Post stack depth migration) the obtained results showed an astonishing better resolution as it is depicted in the figure below.
