HOUSTON, Sept. 9
-- Flow tests, limited by equipment capacity, on the Guara presalt discovery well 1-SPS-55 (1-BRSA-594) drilled off Brazil produced at about 7,000 bo/d, according to Petroleo Brasileiro SA (Petrobras).

From these tests, the company estimates that the well initially could produce at about 50,000 bo/d and that the area contains about 1.1-2 billion bbl of recoverable 30° gravity oil.

The well, drilled in mid-2008, is on Block BM-S-9 in the Santos basin about 310 km off Sao Paulo state and 55 km southeast of the Tupi 1-RJS-628A (1-BRSA-369A) discovery well. Water depth is 2,141 m.

The operator Petrobras holds a 45% interest in the block. Companies holding the remaining interest in the block are BG Group 30% and Repsol YPF SA 25%.
