Offshore publishes Viridien Foz do Amazonas Basin article in its Offshore Brazil Regional Report 2025

Paris, France | Oct 28, 2025

Eduardo Leaubon, exploration geoscientist with our Earth Data team, discusses the prospectivity of deepwater Amapá, offshore Brazil, with a focus on the Upper Cretaceous turbidites.

In an exclusive article published by Offshore in August 2025 and featured in its recently released  Offshore Brazil Regional Report 2025, Eduardo describes how seismic reimaging and new data acquisition have significantly improved the understanding of subsurface geology in the underexplored Amapá deepwater region.

High-resolution seismic imaging techniques, such as elastic full-waveform inversion, provide detailed velocity models crucial for frontier exploration in areas with sparse well control.

The improved imaging has made it possible to map depositional features such as channel levee systems, lobes and other turbiditic geometries in detail, reconstructing sediment transport systems and paleoenvironments with a higher degree of confidence.

With momentum growing across the Brazilian Equatorial Margin, the Foz do Amazonas Basin is emerging as one of the country’s most promising frontier opportunities. High-resolution seismic imaging — combined with advanced interpretation techniques — is transforming legacy data into actionable insight, supporting more confident exploration in geologically complex settings.
