HOUSTON, Apr. 19
-- Petroleo Brasileiro SA (Petrobras) started a 2-year, 6,000 bo/d production test of the presalt Brava discovery well 6-MRL-199RJS to the P-27 semisubmersible production platform in Marlim field.

The company drilled the Brava discovery well in 2010 through 1,000 m of salt to a 5,000 m TD. The well is in 648 m of water and found 29° gravity oil in carbonate reservoirs at 4,460 m. Petrobras estimated that the reservoir might recover 380 million boe (OGJ Online, June 7, 2010).

Marlim field, discovered in 1985, produces from reservoirs at about 3,380 m.

Brava is the third reservoir to produce oil from presalt reservoirs in the Campos basin. Petrobras started production from the presalt in Jubarte in September 2008 and from Baleia Franca in July 2010.
