Petrobras’ extension well confirms discovery in pre-salt of Santos Basin

Posted on 17 April 2012

Petrobras has completed drilling an extension well that confirms good quality oil samples in the pre-salt of the Santos Basin.

Petrobras has completed drilling extension exploratory well 3-BRSA-1032-RJS (3-RJS-697), located in the Iara Evaluation Area, in the pre-salt of the Santos Basin. The result was confirmed through good quality oil samples ranging from 21º and 26º API in carbonate reservoirs of the pre-salt, as of 5,430 meters in depth, which demonstrates the high potential of the pre-salt reservoirs of this area.

The well is 223 km off the coast of Rio de Janeiro, Brazil, some 9 km from the discovery well, at a water depth of 2,150 meters. The well, informally known as Iara Oeste, is the third well drilled in the Discovery Evaluation Plan 1-BRSA-618 (Iara) and reached 6,050 meters TD.

Petrobras is the operator of the consortium (65%), in partnership with BG Group (25%) and Galp Energia (10%). The consortium will advance the activities set forth in the Evaluation Plan approved by the National Petroleum, Natural Gas and Biofuels Agency (ANP), including formation tests to evaluate the productivity of the reservoir.
