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 database - 137,293 km of 2D TTI PSDM and 5,768 km2 3D TTI PSDM

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

Southern Basins SeaSeep Program

Our Brazil SeaSeep program includes acquisition of multibeam data, coring and geochemical analysis over an area of approximately 200,000 square kilometers, including 330 SGE cores and 33 JPC cores and 33 heat flow measurement locations. In progress; completion date March 2019. Once completed, ... Read More

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

Campos Basin

The Campos Basin blocks are an extension of the pre-salt play, where multiple world-class discoveries have been made. We have identified multibillion barrel prospects on our own existing high-quality seismic data over these blocks and look forward to working with the government and our ... Read More
