Petrobras confirms extension of Carcara discovery

A third exploratory well drilled by Petroleo Brasileiro SA (Petrobras) in the Carcara area of the ultradeepwater Santos basin again confirmed the presence of good quality light oil of 31º gravity in presalt reservoirs.

Well 3-SPS-104DA, known as Carcara Northwest, lies 226 km from Sao Paulo state and 5½ km northwest of the original discovery well on Block BM-S-8 in 2,204 m of water.

Pressure data indicate the oil is part of the same accumulation as two other wells previously drilled in the area, confirming the westward extension of Well 4-SPS-86B (OGJ Online, May 29, 2015). Well 3-SPS-104DA encountered carbonate reservoirs with excellent features situated just below the salt layer at 5,870 m, finding a 318-m oil column with no water contact, Petrobras says.

The company says it will conduct formation tests through recently drilled Well 3-SPS-105 to determine the presalt reservoirs’ productivity.

Petrobras operates Carcara with 66% interest. Partners are Petrogal Brasil SA 14%, Barra Energia do Brasil Petroleo e Gas 10%, and Queiroz Galvao Exploracao e Producao SA 10%.
