Prestack Depth Migration Services
We offer both ray based and wave based prestack depth migration (PSDM) algorithms. The ray based PSDM is a wavefront reconstruction Kirchhoff summation algorithm. The wave based PSDM is a two-way Reverse Time Migration algorithm.
The appropriate algorithm is selected based on the geological setting and the imaging objective of the project. Both wave equation based and ray trace based algorithms are used for both model building and final imaging.
No data decimation or conditioning is applied prior to prestack depth migration. All prestack depth migrations output fully migrated volumes with image gathers output at each migrated bin.
Our prestack depth migration algorithms are implemented for any case of anisotropy. This is combined with unique workflows for the construction of anisotropic earth models.
