ERL Special Talk: Ping Wang (CGGVeritas): Full Waveform Inversion for Subsalt Imaging 

FWI is considered the most promising data-driven tool to automatically build velocity models by iteratively minimizing the difference between recorded data and modeled synthetic data. However, its impact on subsalt imaging had been long missing until the recent emergence of reflection FWI and advancement of diving-wave FWI. We present a few FWI approaches that we observed are able to update either the salt body or subsalt velocity or both and thus improve the subsalt imaging.
