Kirchhoff versus One-Way on a Gulf of Mexico 2D Salt Synthetic

This short section looks at a major reason we should use highly accurate imaging techniques. It compares a one-way phase screen to a maximum amplitude Kirchhoff method. Improvements at both the salt-sediment interface and below the salt provide clear evidence of the superiority of the more accurate one-way technique.

A series of widely spaced shots were synthesized over the model shown in the upper right corners of both halves of Figure  2. Receivers for each shot were spread across the entire model surface. The one-way technique clearly does a better job overall and is much better at the salt-sediment interface and in the sub salt section of the model.
