According to major Brazilian O&G market sources, the official Brazilian pre-salt area boundaries will have to be expanded due to various pre-salt discoveries beyond presently acknowledged frontiers.Companies such as Petrobras, Repsol, Anadarko and Shell have made important pre-salt discoveries away from the Picanha Azul area where the Tupi field is located and where all the blocks drilled presented commercial hydrocarbon accumulations. Repsol is making history in Brazil with block ES-T-737, where they are drilling to a goal depth of 7,500m (24,606ft). Repsol is hedging on finding oil under the salt layer in an area beyond officially recognized pre-salt boundaries.

Petrobras and PGS (Petroleum Geo-Services) announced on June 14th, 2010 in Rio de Janeiro that they have signed an agreement for PGS to install a permanent seismic monitoring system in the Jubarte field in the North Campos Basin, Espirito Santo province, offshore Brazil.PGS will install its OptoSeis fiber-optic system, as well as perform seismic acquisition and data processing for the project. This project is a significant step forward in the use of geophysics for reservoir surveillance, in particular 4D-4C seismic to map the flow of fluids in Brazil's deep water reservoirs. It is hoped that the system will improve the quality and timeliness of information that Petrobras' geophysics team provide their counterparts, reservoir and production engineers, that operate the fields.
