Abstract

In conventional reverse‐time depth migration, successive time slices from a stacked seismic section are inserted as boundary values at the top of the image space, and the wavefield is extrapolated backward in time until time = 0. The resulting fixed‐time snapshot of the propagating wavefield, in space, is the migrate d image.
