Finite-difference kinematic migration as one of the ways of obtaining information about seismic boundaries and seismic velocities in geological environment

Migration is divided into kinematic and dynamic. Dynamic migration allows you to show the internal structure of geological environment with all its features as the dynamic parameters of the observed wave field. The kinematic migration gives information about the seismic boundaries and seismic velocity. The result of kinematic migration can be further used to realize the dynamic migration.

The kinematic migration is based on a downward continuation of the time field of a direct and reversed travel-times that is realized by solving the eikonal equation on a special type of grid with finite- difference method. At the same time kinematic migration can be used travel-time curves of the reflected and refracted waves. The report focuses on the subject of obtaining information about the seismic boundaries and seismic velocity in the geological environment using the finite-difference kinematic migration.
