TGS offers extensive coverage over hydrocarbon-rich basins and highly prospective Pre Salt trend
TGS surveys in the area include extensive regional 2D programs of both legacy and reprocessed datasets, 3D surveys, interpretive studies (Play Fairway Analysis and Facies Mapping), and most recently a Campos/Santos regional SeaSeep survey that consists of multibeam data acquisition, seafloor coring, and geochemical analysis both inside and outside the pre-salt region.

Brazil Multibeam & Coring
The project will cover existing TGS surveys in these hydrocarbon rich basins as well as the pre-salt trend where many untested structures exist. Data will be available in Q4 2018 over the ‘Round 16’ licensing areas scheduled in 2019. Final results in all areas will be available in late ... Read More

In progress; completion date March 2019. Once completed, the project will provide cohesive bathymetry and backscatter grids and a well distributed geochemical sampling and analysis package across the Campos and Santos Basins.Olho De Boi
Olho de Boi covers 5,768 km2 located about 60 km northeast of Repsol Sinopec's world class pre-salt discoveries, Gavea and Pão de Açúcar. These are part of the largest-ever oil and gas discovery in the Campos Basin's pre-salt trend, in what many consider to be Brazil's richest oil and gas ... Read More

Olho de Boi covers 5,768 km2 located about 60 km northeast of Repsol Sinopec's world class pre-salt discoveries, Gavea and Pão de Açúcar. These are part of the largest-ever oil and gas discovery in the Campos Basin's pre-salt trend, in what many consider to be Brazil's richest oil and gas area.Processing was completed by TGS in 2015, and Pre-stack time (Kirchhoff PSTM) and Pre-stack depth (TTI Kirchhoff PSDM & TTI RTM PSDM) products are currently available for license.

Santos 2D TTI PSDM: Phase 3 was a complete reprocessing effort that started from field tapes and included full source and receiver deghosting, improved demultiple techniques, TTI model building and migration. The lines reprocessed in the Phase 3 area now provide an upgrade to the existing legacy Isotropic PSDM, as well as a seamless tie with the lines in the adjoining Phase 2 area.
The completion of Phase 3 reprocessing adds to the existing Santos Phase 1 and Phase 2 datasets. Total km’s reprocessed in Phase 3 = 22,800 km. Total Santos TTI PSDM data available = 76,012 km.

South Brazil Interpretation
- TGS has developed a Sequence Stratigraphic Study and Play Fairway Analysis for basins in the Equatorial margin and Southern basins of Brazil.
- The sequence stratigraphic study used well data supported by TGS-WesternGeco 2D seismic data to map the depositional systems in each of the basins. The depositional systems are presented in the form of sequence constrained depositional environment and facies distribution maps.
- The study also delivers sequence stratigraphic interpretation, gross depositional environment and facies association interpretation for all wells.
- For the play fairway analysis project, seismic facies analysis was completed throughout the entire 2D seismic database. In addition, basin-wide temperature modelling and a study of field analogues to guide and inform the analysis of the play fairway systems for each of the basins was completed. This enabled the definition of common risk segments of reservoir, seal and source rock distribution, trapping mechanism, source rock maturity and migration pathways.
