ABSTRACT

This tutorial describes mixed-domain wave-equation migration and migration velocity analysis techniques in a unified theoretical framework. I review two of the most general mixed-domain migration methods, Fourier finite-difference and generalized screen, and show how other commonly used wave-equation migration methods come about as special cases. I use the Born approximation to derive general expressions for the wave-equation migration velocity analysis operator, and show two simple backprojection examples built around a North Sea dataset.
