Rio de Janeiro, September 28, 2015 – Petrobras informs that the drilling of the third well in Carcará area (Block BM-S-8), located at Santos Basin´s ultra-deep waters, confirmed the light oil potential in pre-salt’s reservoirs.

The well 3-SPS-104DA (Petrobras nomenclature), informally known as Carcará Northwest, is located in the area of Discovery Evaluation Plan of the discovery well 4-SPS-86B (Carcará). The new well is located at 5.5 km northwest of discovery well, at water depths of 2,024 and about 226 km from the coast of the state of São Paulo.

This well has proved the presence of good quality oil (31º API), in carbonate reservoirs of excellent quality, located right below the salt layer, at 5,870 meters depth. The well found a significant oil column of 318 meters, and it has not attained the oil/water contact from this accumulation.

The pressure data show it is in the same accumulation of the two other wells previously drilled in the area, confirming the westward extension of the discovery of the 4-SPS-86B well.

Continuing the scheduled operations under the Discovery Evaluation Plan, in the coming days will begin the evaluation of the pre-salt reservoirs´ productivity through formation tests in well 3-SPS-105, whose drilling was recently completed.

The Discovery Evaluation Plan of Carcará approved by Brazil´s Nacional Petroleum, Natural Gas and Biofuels Agency (ANP) is expected to finish by March 2018.

Petrobras is the operator of the cnsortium (66%), in partnership with Petrogal Brasil (14%), Barra Energia do Brasil Petróleo e Gás (10%) and Queiroz Galvão Exploração e Produção S.A. (10%).
