Recently, fast marching methods (FMM) beyond first order have been developed for producing rapid solutions to the eikonal equation. In this paper, we present imaging results for 3-D prestack Kirchhoff migration using traveltimes computed using the first-order and secondorder FMM on several 3-D prestack synthetic and real data sets. The second order traveltimes produce a much better image of the structure. Moreover, insufficiently sampled first order traveltimes can introduce consistent errors… CONTINUE READING
