Petrobras finds presalt oil under Marlim field

By OGJ editors
HOUSTON, June 7 -- Petroleo Brasileiro SA (Petrobras) drilled an exploratory well through salt in Marlim field in the Campos basin and found carbonate reservoirs from which preliminary estimates indicate it could recover 380 million boe.

Petrobras drilled the Brava (6-MRL-199D-RJS) well, in 648 m of water 170 km off Macae, through 1,000 m of salt to a total depth of 5,000 m and found 29° gravity oil in presalt carbonate reservoirs at 4,460 m. Regular pay in Marlim field, discovered in 1985, is at about 3,380 m.

The company plans to conduct tests of the well, which is near the installed infrastructure in Marlim and Voador fields. The discovery well is 4½ km from the P-27 platform.

This accumulation will be the object of an assessment plan to be submitted to the National Petroleum Agency soon, Petrobras said.
