Abstract:ABSTRACT. This paper shows the application of Phase Shift Plus Interpolation Split-Step (PSPI-SS) wavefield extrapolation operator coupled with the excitationtime imaging condition to perform prestack seismic depth migration of common shot profiles. The migration methods which are characterized by the use of different propagators for the source and receiver wavefields are called hybrid migration methods. Normally, the source wavefield is determined by the computation of the traveltimes from the solution of the… Show more
