Petrobras has started the Extended Well Test (EWT) of the Brava area, in the Campos Basin pre-salt, in the Production Concession area of Marlin field, located 170 km from the city of Macaé, RJ.

The EWT which is expected to last two years and have a daily production of 6,000 barrels of oil per day is being done by well 6-MRL-199-RJS, interconnected to platform P-27, which was already under production at Marlin field. This is the third reservoir to produce oil in the Campos Basin pre-salt. The first reservoir was in the Jubarte field in September of 2008; subsequently, in July of 2010, Petrobras started to produce in a reservoir in the Baleia Franca field's pre-salt.

The Brava EWT will enable Petrobras to obtain more information about the reservoir's characteristics, which will assist in the preparation of the definitive production development project. This data will also be important to study the characteristics of new wells in the Marlim and Voador fields.
