This model was created by John Etgen and Carl Regone on the Amoco CM-5 in Tulsa. Joe Dellinger got permission from Amoco just before the merger to publicly release these data.

Overview

This model was created by John Etgen and Carl Regone at Amoco for the paper "Strike shooting, dip shooting, widepatch shooting — Does prestack migration care? A model study".

This is a 2D dip line subset of the full 3D dataset. This dataset was meant to be a severe test of 2.5D Kirchhoff migration (the model is invariant in the Y direction). It was created to advocate wavefield migration methods, so it illustrates the limitations of Kirchhoff!
