Petrobras' proven pre-salt reserves are up 43% in 2013. Since 2007, the company has been adding increasing amounts to its proven reserves coming from the pre-salt layer, which extends from the south of the state of Espírito Santo to the state of Santa Catarina. More than a quarter of the proven Petrobras reserves come from the pre-salt. In 2013, 42 wells were drilled in the pre-salt layer, coupled with the performance of the production platforms in the Campos and Santos basins, allowing reserves to increase by 43%.
Along with the increase in reserves, production has also increased in pre-salt layer. On January 13, 2014, a second production well, with a production of 28,000 bo/d, on the Cidade de Paraty platform came on stream in the Lula field. This platform now produces a total of 58,000bo/d.
As a result, a new daily record was reached on January 14, 2014, where oil production from Petrobras operations in the pre-salt surpassed the level of 390,000bo/d. The previous record was set on December 24, 2013, with 371,000bo/d.
Of the two basins in production in the pre-salt, Campos and Santos, the latter contributed 51% to this record of 390,000bo/d, with nine production wells in operation, proving the high productivity of the fields discovered in pre-salt layer. Average production per well, in commercial operation, in the pre-salt Santos basin hub has been around 25,000 bo/d per well, which is higher than levels recorded in the North Sea (15,000 bo/d per well), and the Gulf of Mexico (10,000 bo/d per well).
Cumulative production in the pre-salt fields, which started in 2008, has surpassed 290Mmb/oe. The company has reached a pre-salt production in six years that is almost double the cumulative production of the Garoupa field (156Mmboe) in the Campos basin.
In December 2013, three declarations of commercial viability demonstrate the feasibility of producing in three separate pre-salt areas: Lapa (Carioca), Búzios (Franco) and Sul de Lula (Sul de Tupi), all in the Santos basin.
Additionally, pre-salt discoveries in fields already in production in the Campos basin, such as Albacore, Caratinga and Marlim Leste, contributed to the increase in reserves in 2013.
Another result supporting future pre-salt production area planning is its 100% geological success rate of 2013, i.e. all pre-salt wells drilled in 2013 indicate the presence of hydrocarbons.
In 2014, 17 new wells will be connected to platforms already installed in the pre-salt Santos basin hub.
In 2H 2014, two new platforms will come on stream in the pre-salt hub in the Santos basin: the Cidade de Ilhabela platform in the Sapinhoá Norte field, and the Cidade de Mangaratiba platform in the Iracema Sul field will increase daily production capacity by 300,000bo/d in the pre-salt hub in the Santos basin. These two new platforms will be connected to another five new wells in 2014.
