3-D interval velocity analysis

Before migration, inversion, or geostatistical correlation of parameter estimates to characterize a reservoir can be done, velocity analysis is the prerequisite. In particular, it would be valuable to have a method of estimating 3-D interval velocities as a function of spatial coordinates. Interval velocities are required to perform depth migration, and 3-D becomes important to take advantage of the 3-D reflection seismic surveys now routinely being conducted over known, often producing, reservoirs. I recognize the magnitude of this problem and its impact on dependent processes such as migration/inversion. I am interested in perhaps using the Connection Machine at the SEP to approach this large and computer-intensive problem.
