Some considerations on the steep-dip finite-difference migration

The practical implementation of a steep-dip migration scheme by the finite-difference method is the main concern of this paper.Successful steep-dip migration requires not only an accurate one-way wave equation but also an accurate difference approximation of the differential equation.Accurate one-way equations can be obtained using an optimization method (Lee and Suh, 1985).This optimization method can also be applicable to the derivation of accurate difference operators.This paper describes a practical approach to the steep-dip migration using optimized one-way and difference operators.
