... is 2–3 Hz. For land data, the lowest frequency band that we can use for FWI is 2–4 Hz. Wide-azimuth (WAZ) acquisition facilitates FWI by highly improved data coverage with a higher signal-to-noise (S/N) ratio, better illumination, and longer offset. FWI was successfully carried out with both marine...
