Petrobras initiates fourth Santos basin extended well test

Offshore staff

RIO DE JANEIROPetrobras has started up an early production system (EPS) on the Sépia (ex-Nordeste de Tupi) area in the presalt Santos basin offshore Brazil.

The operation is under way from the FPSO Cidade de São Vicente, 185 km (115 mi) offshore the Rio de Janeiro coastline, which will produce around 20,000 b/d of oil during the test period.

The main goals are to collect technical information on the behavior of the reservoirs and outflow of the oil via the underwater pipes to support development of the definitive production system, scheduled to start operations in the area in 2020.

The vessel, installed in a water depth of around 2,200 m (7,219 ft), is connected to the 1-RJS-691 well. It will remain in the location for 180 days.

This is Petrobras’ fourth EPS in the “Onerous Assignment” area of the Santos basin. Produced oil (26º API) will be transported by shuttle tankers.
