Presalt oil reserves surge in Santos basin offshore Brazil

Offshore staff

RIO DE JANEIRO – Petrobras’ proven presalt reserves increased 43% last year compared to 2012.

In 2013, the company drilled 42 wells in the presalt layer which extends from the south of the state of Espírito Santo to the state of Santa Catarina. All indicated the presence of hydrocarbons. The results, combined with performance of production platforms in the Campos and Santos basins, led to the large reserves increase.

Last week a second production well came onstream through the Cidade de Paraty facility on the Lula field, lifting production to 58,000 b/d of oil.

On the same day (Jan. 14), the company’s presalt oil production reached a new high of more than 390,000 b/d.

In the Santos basin, which provides 51% of presalt oil output, nine production wells are in operation. Average production per well in the presalt Santos basin hub is around 25,000 b/d.

Last month the company issued declarations of commercial viability for three more Santos basin presalt areas: Lapa (Carioca), Búzios (Franco) and Sul de Lula (Sul de Tupi). 

This year Petrobras expects to connect 17 new wells will be connected to platforms already installed in the presalt Santos basin hub.

In the second half of 2014, two new FPSOs will come onstream: the Cidade de Ilhabela platform in the Sapinhoá Norte field, and the Cidade de Mangaratiba platform in the Iracema Sul field, increasing presalt oil production capacity in the basin by 300,000 b/d.

The new platforms will be connected to another five new wells later in the year.
