Revisiting the Brazilian Equatorial Margin with FWI and its impact on interpretation in an exploratory frontier

Recent technology advancements have enabled us to revisit the Foz do Amazonas (2014) and Barreirinhas (2016) narrow-azimuth towed-streamer (NATS) seismic surveys and tackle specific imaging challenges in a way that the legacy processing could not. In an exploratory frontier such as the Brazilian Equatorial Margin (BEM), the petroleum system knowledge is limited, with few wells and no significant commercial discovery in the area yet. Thus, high- quality seismic data is crucial for reducing risk in the initial exploration phases.
