Modeling and Migration with the Monochromatic Wave Equation -- Variable Velocity and Attenuation , by Einar Kjartansson

A review of the theory for the 45-degree monochromatic wave equation leads to a simple scheme for migration and diffractions that can readily handle lateral variations in velocity. Anelasticity can be included without a change in the finite difference algorithm. Sample Fortran programs are given for both modeling and migration of zero-offset sections for arbitrary velocity and Q structures, with synthetic examples. The algorithm has been adapted for large datasets by taking advantage of the speed of the SEP array processor.
