Abstract

Summary

Full waveform inversion (FWI) has become the preferred method for updating shallow sediment velocities. However, due to limited diving-wave penetration depth of WAZ acquisition and the geologic complexity of the region, updating subsalt velocities in the Gulf of Mexico remains challenging. Through a scheme incorporating reflection data, we extend the reach of FWI beyond diving-wave penetration depth. We present examples from the Mexican waters of the Perdido fold belt where reflection FWI successfully updates velocities at depths out of reach of diving wave-based FWI and in geologically complex situations where tomography typically struggles, including intrasalt and subsalt velocity update examples.
