Abstract

This chapter presents a new method of migration of the elastic wavefield. It is based on the Born approximation of the forward modelling operator for the elastic, which is obtained as an extension of the Born approximation for the acoustic field to the case of the elastic wavefield propagation. We present a detail mathematical derivation of the migration operators for the acoustic and elastic cases. The numerical experiments based on these operators are conducted for a set of synthetic multilayered models with curvilinear boundaries between the layers. We also present a comparative study of the migration images produced by the migration of the acoustic and elastic wavefields and examine the sources of false boundaries appeared in some of these images.
