Rock Physics-Guided Velocity Modeling in Conjunction with Tomography and FWI for Imaging

We present a workflow for rock physics-guided velocity modeling for depth imaging and applications in real case studies from the Gulf of Mexico. The rock physics model used in this method contains both mechanical and chemical compaction that depends on thermal history and controls the effective stress variation in depth. We highlight the capability of this method in predicting the velocity for unknown areas such as places that lack well control or beyond the total depth of a well. The assumptions and source of error for this method are also discussed.
