At PSS-Geo we work on own coded Kirchhoff migration algorithm. Per customers' requests we perform Beam migration or use other moderns algorithms and theirs updates.
PSS-Geo have been working as tester and debugger for many companies which are developing migration algorithms. That lets us to be on the easiest access to the world latest migration algorithms updates. If customer' data required so, we suggest to the client considering to apply particular solution.
On the daily base, we prefer to use Kirchhoff alghorithm and the most important: an accurate migration velocity field (picture above). Based on the 17 years of experience, we conclude that for a real field data a migration velocity privilege in imaging. For PSDM model building, we also prefer to use Kirchhoff and tomography.
