RIO DE JANEIRO – Petróleo Brasileiro S.A. reports the start of an extended well test (EWT) in the Aruanã area offshore in southern Campos basin block C-M-401. The EWT is expected to run about six months at as much as 12,000 b/d of oil through the FPSO Cidade de Rio das Ostras.
The test of well 1-RJS-661 belongs to the Discovery Assessment Plan approved by Petroleum Agency for the subsequent development of the area. The exploratory block is between Pampo and Espardarte fields, in water depths ranging from 350 to 1,500 m (1,148 to 4,921 ft).
Formation tests done after drilling the well showed 27°API oil and recoverable volumes of approximately 280 MMbbl of oil.
Petrobras says the EWT is part of the studies program to better characterize the reservoir, fluids, and production potential.
