3-D Prestack Imaging and Velocity Analysis by a Quasi-Monte Carlo Method. FinalReport, August 1, 1994-October 1, 1995

摘要

Two major accomplishments were achieved in this report; a new theoreticalunderstanding of quasi-Monte Carlo 3-D prestack migration (QM) is established, and the authors proved, for the first time with seismic field data from W. Texas, that quasi-Monte Carlo 3-D prestack migration (QM) is 4-8 times more efficient than standard Kirchhoff migration. This verified findings from the authors' theoretical predictions and their numerical simulations.
