Kirchhoff prestack depth migration in a homogeneous triclinic velocity model for P, S and converted waves

Vaclav Bucha


The ray-based Kirchhoff prestack depth migration is used to calculate migrated sections in a simple homogeneous triclinic velocity model. The ray-theory recorded wave field corresponding to P, S and converted waves is generated in the velocity model composed of two homogeneous layers separated by a non-inclined curved interface. The anisotropy of the upper layer is triclinic. We apply the Kirchhoff prestack depth migration to single-layer velocity model with the same triclinic anisotropy as in the upper layer of the velocity model used to calculate the recorded wave field. We show and discuss the results of the migration for different types of waves.
