Abstract

The algorithm presented in this paper uses the implicit finite difference scheme (45 degree approximation), for the propagation. The advantages by choosing this alternative for a migration implementation are well known: Since the extrapolation operator is only 3 points long, it is robust in cases with considerable velocity variations. In addition, run time on computer is very short, compared to some other algorithms. The disadvantage is of course the low performance for steep dips
