(1996) described a method for performing prestack depth migration by computing Green's functions from the surface with a wavefield extrapolation method and then using them in a frequency-dependent Kirchhoff migration. The primary benefit of this method is that one can sort the output of a wave equation migration by source-receiver offset, thus creating common image point gathers indexed or binned by source-receiver offset, a technique derived from CMP processing that is used in traveltime-table-driven Kirchhoff migrations. The biggest drawback of this method is its computational expense, potentially large memory requirements, and awkward data handling, particularly in the 3D case. Since the method was originally proposed, computer capability has expanded rapidly, enabling implementation of this approach in 3D. I discuss why this method is of potential interest, then briefly recap the derivation of Ehinger et al. (1996), describing its application to different 3D acquisition geometries. Lastly, I show an example of this method applied to a Gulf of Mexico dataset.
