In the framework of subsurface exploration, the availability of non-seismic datasets represents a great opportunity to complement and enrich seismic processing and imaging with independent geophysical information. In the presence of heterogeneous datasets, the definition of the optimal workflow is paramount to fully leverage the uniqueness of each of the measurements involved. A novel workflow involving electromagnetic, gravity and seismic datasets, combined in a multi-step sequential and simultaneous joint inversion approach is presented in the context of near-surface characterization and statics, with application to a survey recently acquired in the Middle East. By maximizing the information extracted from the multiphysics dataset, effective and accurate near surface modeling is achieved, leading to a static solution superior to the seismic-only benchmark. Finally, the multiphysics modeling capabilities are extended to depth imaging for initial velocity model building.
