This work presents two different ways of performing the reverse time migration using the complete wave equation: rtm by interpolation and by the pseudo analytical method. In rtm by interpolation, the wavefield evolution in time is based on the wave equation solution for constant velocity case.

Pdf Reverse Time Demigration Migration This work presents two different ways of performing the reverse time migration using the complete wave equation: rtm by interpolation and by the pseudo analytical method. In rtm by interpolation, the wavefield evolution in time is based on the wave equation solution for constant velocity case. We present a reverse time migration algorithm whose extrapolator is based on an extension of the pseudo analytical (pa) method, to compensate for amplitude loss and dispersion due to propagation in viscoacoustic media. The impulse response of this algorithm, which is known as reverse time migration, is shown in figure 4.3 21. note that the algorithm can handle dips up to 90 degrees with the accuracy of phase shift migration. We use an extension of the pseudo spectral method, called the pseudo analytic method, to formulate a 3d tti reverse time migration scheme. the pseudo analytic method provides accurate, nearly non dispersive wave propagation with a simple 2nd order time stepping scheme. I compare the results of three numerical schemes for seismic modeling and reverse time migration: the rapid expansion method, the lax wendroff method, and the pseudo analytical method.
