Offshore projects contribute over 90% to Brazil's oil and gas production of about 860 million barrels of oil equivalent (MMboe), owing to the rapid development of deep water and ultra deep water oil and gas projects in the country. The country's major offshore development started in 2007 with the discovery of the Tupi oil field, which is expected to hold 5-8 billion barrels of resources. Subsequently, the country's pre-salt development activities have now extended to neighboring areas such as the Campos and Espiritu Santo basins, which have witnessed several major discoveries. Brazil's government is focusing on the development of offshore oil and gas activities, especially in pre-salt and post-salt areas. FPSOs are expected to play a key role in the development of deep water and ultra deep water projects in Brazil. Currently, about 40+ FPSOs are expected to be developed globally by 2015, of which Petrobras alone plans to add 12 in Brazil.
