We present a case study using full-waveform inversion for a subsurface model update, including salt boundary and salt velocity delineation, in a geologically complex area in the western Gulf of Mexico. Geology here comprises rugose and deformed shallow salt bodies with intra-canopy high dip and close-proximity structures resulting from regional basinward gliding, associated compressional mechanisms, and salt movement. Interspersed among the salt bodies are rafted, high-velocity carbonates that can effectively mask salt boundaries. Given the challenges of model building in such a setting, a data-fitting approach such as full-waveform inversion with access to the full reflectivity record is proposed to provide practical solutions for an effective salt model update. Improving confidence in the seismic image and subsequent geologic interpretation remain the core objectives.
