In this study we conducted Full Waveform Inversion (FWI) for an offshore prospect in the Mississippi Canyon protraction area of the GoM to improve the image quality at the reservoir where we observed poor illumination. We used wide azimuth towed streamer (WATS) data with an 11 Hz starting model. We improved model resolution to 24 Hz. The resulting velocity model and FWI derived reflectivity (FDR) reveal previously unseen structures at the reservoir level, and aid interpretation with better horizon continuity throughout the study area as a result of the improved resolution and more consistent image amplitudes.
