Summary



An ongoing, preliminary study of salt flank illumination using data from Vinton Dome, Louisiana is described. This study is part of a larger, Department of Energy (DOE) funded project carried out by the Allied Geophysical Laboratories (AGL) at the University of Houston in conjunction with Output Exploration (OPEX). The ultimate goal of the project is to produce better images of potential, by-passed hydrocarbon reservoirs on the flanks of the salt dome. To achieve this goal, the flanks of the dome must be properly illuminated, and our migration must be able to continue the energy backward in time to these portions of the subsurface. Therefore, we felt that a study of illumination and continuation of the wavefields toward the salt flanks would be beneficial. While the data and structure are 3-D, we begin our analysis with a dip line radial to the salt dome.
