Examples of DMO and Prestack Migrations
Recognize properties of the DMO operator.
Know how to test a DMO operator.
Identify areas where DMO benefits data.
Identify areas where DMO may harm data.
Know that test results only evaluate the implementation of an algorithm, not the algorithm.
Identify the differences of time and depth migrations when they are applied to structured data.

This volume, SEG Course Notes Series No. 14, is designed to give the practicing geophysicist an understanding of the principles of prestack migration, presented with intuitive reasoning that avoids difficult math. Modeling with common-shot record and a constant-offset section are used to introduce prestack migration. New material in this revised edition of the original 1998 book includes algorithms that lead to and include Claerbout’s inversion method.
