Petrobras said that a third exploratory well found light oil in the Carcara offshore discovery in the Santos Basin offshore Brazil, confirming that the find extends well beyond the initial discovery. The Carcara NW well lies 5.5 km (3.4 miles) northwest of the initial discovery well and was drilled to a depth of 2 km. When discovered in 2012, Carcara was the biggest oil column ever found in Brazil’s pre-salt region. Petrobras, the operator, holds a 66% interest in the area with the remaining interests held by Galp Energia (14%), Barra Energia do Brasil Petroleo e Gas (10%), and Queiroz Galvao Exploracao e Producao (10%).
