Weidlinger Associates Inc., 4410 El Camino Real #110, 94022, Los Altos, CA, U.S.A. aut Modeling, ray tracing, and block nonlinear travel-time inversion in 3D [Elektronische Daten] [V. Pereyra] We describe an integrated forward and inverse three-dimensional modeling system that can deal with complex geological structures. The system has been designed to handle large-scale problems by using a distributed approach. It uses seismic ray tracing for forward simulation, time-to-depth mapping, and nonlinear travel-time inversion. A novel decomposition method is our tool to attack large-scale problems in a parallel approach. The system is fully implemented and we demonstrate its performance with synthetic examples.
