Call to ActionTGS’ Kirchhoff depth migration has been proven to be one of the best Kirchhoff depth algorithms in the industry.
It is a maximum energy implementation and utilizes 3D dynamic ray tracing. The algorithm supports isotropic, VTI and TTI anisotropy. It has been used extensively for narrow and wide-azimuth surveys in a wide variety of locations and geological settings. In Kirchhoff PSDM proper weighting function including geometrical-spreading compensation and Beylkin determinant is applied to preserve the migration amplitude for both flat and dipping reflectors.
TGS prestack Kirchhoff time migration is implemented with ray bending, anisotropy
