Petrobras confirms productivity of Santos basin’s Carcará area

RIO DE JANEIRO -- Petrobras has concluded two formation tests in the 3-SPS-105 well, confirming the high productivity of the pre-salt carbonate reservoirs. The well, informally known as Carcará Norte, is in the area of the Carcará Discovery Evaluation Plan (PAD), 4.6 km north of the discovery well (4-SPS-86B), in a water depth of 2,070 m, and it reached final depth of 6,338 m, inside basaltic rocks.

Petrobras conducted two formation tests in the pre-salt reservoirs, confirming excellent productivity in both intervals. The well’s output potential may be equivalent to the results achieved by the best producing wells of the pre-salt layer in the Santos basin, with good quality oil (31º API), free from contaminants.

The results from the fluid and pressure analyses in the formation tests in 3-SPS-105, and the tests conducted in the discovery well and the Carcará Noroeste well (3-SPS-104DA) indicate that it is a single oil accumulation.

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

The consortium will give continuity to the activities of Carcará’s PAD, approved by the National Oil, Natural Gas and Biofuels Agency (ANP), with conclusion expected for March 2018.
