Prestack Time Migration

For those areas where the complexity doesn’t require the use of PSDM, the Pre-Stack Time Migration (PSTM) delineates the geologic structures efficiently. Our software has an algorithm for 2D and 3D Kirchhoff PSTM extremely optimized for the use of cluster systems.

This technology shortens the computer times, allowing to make several iterations in order to obtain the best result. After each iteration, we perform a quality control with the intention of eliminating the propagation of errors.

As it fundamental bases to make this process we put special attention in the refinement of the velocity model that is used as an initial model. For this we make reference to the iterations made in the velocity analysis made in previous steps.
