Petrobras concluded two formation tests in the 3-SPS-105 (Carcará Norte) well, confirming the high productivity of the pre-salt carbonate reservoirs.
The well is in the area of the Carcará Discovery Evaluation Plan (PAD), 4.6km north of the discovery well (4-SPS-86B), in water depth of 2070m and reached final depth of 6338m, 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 (H2S and CO2).
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 (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.
