Petrobras has completed the drilling and formation test of the fourth exploratory well at Iara area, block BM-S-11, in the Santos Basin pre-salt. These results have strengthened the potential of recoverable light oil from Iara, and have confirmed the discovery of good quality oil (28° API) announced in March.
The carbonate reservoirs, which start at a depth of 5,260m, have shown excellent porosity and permeability with better characteristics than those found in the discovery well (1-RJS-656, Iara). Results have confirmed excellent productivity of the reservoirs. The well is 226km off the coast of Rio de Janeiro, 6km west of the discovery well, at a water depth of 2,197m.
The consortium will proceed with the activities outlined in the evaluation plan approved by Brazil’s National Petroleum, Natural Gas and Biofuels Agency (ANP). Well 3-RJS-715D (3-BRSA-1181D-RJS) is currently being drilled in the centre of the evaluation plan area of Iara.
Petrobras is the operator of the consortium (65%) in partnership with BG E&P Brasil (25%) and Petrogal Brasil (10%).
