Summary:
Full-waveform inversion (FWI) is a high-resolution model building technique that uses the entire seismic record content to build the earth model but have struggles with cycle skipping . Conventional FWI usually utilizes diving and refracted waves to update the low-wavenumber in other words the background components of the model; however, the update is often depth-limited due to the limited offset range acquired. To extend conventional FWI beyond the limits of the transmitted energy, we must use reflection data as well with broad band preprocessing.
