Paper Abstract

Wozniakowski recently achieved a mathematical breakthrough in understanding the tractability of multidimensional integration using nearly-optimal quasi-Monte Carlo methods. Inspired by the new mathematical insights, we have studied the feasibility of applying quasi-Monte Carlo methods to seismic imaging by 3D pre-stack Kirchhoff migration. This earth imaging technique involves computing a large (109) number of 3- or 4-dimensional integrals. Our numerical studies show that nearly-optimal quasi-Monte Carlo migration can produce the same or better quality earth images using only a small fraction (one fifth or less) of the data required by a conventional Kirchhoff migration.
