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.
