Offshore staff

RIO DE JANEIRO – Petrobras has started a new extended-well test in the Sapinhoá North area of the BM-S-9 concession in the presalt Santos basin.

This involves connection of the FPSO Cidade de São Vicente to the 3-BRSA-788-SPS well in a water depth of 2,140 m (7,021 ft).

The FPSO will operate in the area for up to six months, compiling data including information on reservoir behavior and oil flow in the subsea lines. During the initial test phase, the well should produce at around 15,000 b/d as authorized by Brazil’s National Agency for Petroleum, Natural Gas and Biofuels.

Commercial production from the Sapinhoá discovery started up last month through the FPSO Cidade de São Paulo, which has the capacity to process 120,000 b/d of oil and 176 MMcf/d (5 MMcm/d) of gas.

Another FPSO, Cidade de Ilhabela, will begin production from another part of the Sapinhoá field during the second half of 2014. This vessel has a production capacity of 150,000 b/d and 212 MMcf/d (6 MMcm/d) of gas.

Partners in the BM-S-9 block are BG Group and Repsol Sinopec Brasil.
