3D Prestack Depth Migration Using Generalized Screen Propagators

P061 3D PRESTACK DEPTH MIGRATION USING GENERALIZED SCREEN PROPAGATORS Summary The generalized screen propagator (GSP) is a one-way wave equation based wide-angle wave propagator. It can be used for high quality imaging in complex geological structures. Algorithms for both shot-domain and offset- domain data set have been developed. In this paper the advantages of the GSP are briefly reviewed. 3D prestack depth migration examples using synthetic land and marine data sets are presented. Introduction The phase screen method (split-step Fourier method) is based on the one way wave propagation theory. It can be used as a fast propagator for seismic
