The largest offshore sedimentary basin in Brazil, ranging for a total area of over 350,000 square kilometers, all the way from Cabo Frio (state of Rio de Janeiro) to Florianopolis (state of Santa Catarina). The first investments in exploration and production studies for this basin date back to the 1970s.

First oil from the pre-salt cluster

Operations got underway in the Santos Basin pre-salt area on May 1, 2009, by means of an Extended Well Test (EWT) performed by FPSO BW Cidade de São Vicente in the Tupi area.

This date is considered a milestone not only for the company, but also for the Country as a whole.

A year later, on October 28, 2010, the Definitive Production System went on stream at the Tupi Field by means of FPSO Cidade de Angra dos Reis, which has been deployed at about 280 km from the coast and in waters with a depth of 2200 meters.
