Abstract
The ION Picanha™ 3D program reimages 275,000 km² of legacy seismic data into one contiguous data volume, enabling visualisation of the subsurface from the Abimael Propagator in the south-western Santos Basin to the Abrolhos Islands in northern Espírito Santo, more than 800 kilometres away. Regional mapping of well-tied geologic markers at major boundaries such as Albian carbonates, Aptian salt layers, and Brazil’s infamous pre-salt sag sequence, reveal linkages between their geologic history and their robust hydrocarbon accumulations.
The new Picanha 3D dataset provides the ideal foundation for an exploration and production strategy across a world-class petroleum province.
Brazil is the current epicentre of the South American oil and gas industry and ION’s Picanha™ 3D reprocessing program sets a strong foundation for an offshore exploration and production strategy. The multi-client program unifies 115, previously discrete, standalone surveys into one seamless, contiguous regional 3D seismic volume. The integrated program supports national and international oil companies by accelerating exploration insight through regional mapping and prospect generation within an unprecedented 275,000 km2 seismic survey.

The Picanha 3D dataset covers three of the prolific Brazilian offshore basins – Santos, Campos, and Espírito Santo – where both localised and regional studies can be evaluated for an improved understanding of the petroleum system and relationships from field to field. High-profile lease blocks such as Esmeralda, Jade, Água Marinha, and Turmalina are all within the Picanha 3D survey limits and were recently redesignated as Permanent Offer blocks (sure to garner plenty of attention as oil giants search for the next Lula field).
