The technique of vector diffraction stack migration can reduce the computational cost of amplitude-preserving Kirchhoff migration. This extended abstract discusses the abilities, the advantages, problems and limits of the technique, and shows its application to a synthetic dataset. If amplitudes or rock-physical parameters are of interest, the proposed technique is superior to conventional unweighted Kirchhoff migration and of same quality but cheaper than weighted (amplitude-preserving) Kirchhoff migration. In the case of very complex subsurface structures with multi-valued traveltime fields, a weighted Kirchhoff migration should be preferred.
