For vector wave Kirchhoff migration we can use time field functionality
that allows estimating the travel time of the first downward traveling
wave and the scalar. This scalar (which suits Green's function) is used
in Kirchhoff depth migration for the calculation of synthetic gathers.
This option allows considering all wave effects, characteristic of a vector
equation. This enables us to carry out depth migration in media with complex
structure and anisotropy. This travel time estimation differs from that
of the Eikonal equation used in the conventional processing procedures.
A wide range of velocity model assignments
and a friendly interface enables this software package to migrate not only
synthetic gathers, but also real seismic data.
