A024 RANDOM GRIDDING DECOMPOSITION (RGD) IN SEISMIC TOMOGRAPHY Abstract 1 The purpose of this work is to invert crosswell first arrival data on a high resolution velocity grid called the fundamental grid obtained by running several tomographic inversions on grids of smaller size generated randomly. Later the inversion results of these grids are scaled by the ray density and the pixel area to produce a final velocity image with a better resolution. The method has proven a significant gain in computing time for the inversion and has given superior results than those provided using simple grids of similar size especially
