RIO DE JANEIRO – Petróleo Brasileiro S.A. (Petrobras) has confirmed the presence of good quality oil in well 3-RJS-706 (3-BRSA-1132-RJS) in the Iara area of block BMS-11 in the Santos basin presalt.

The well is 226 km (140 mi) off the coast of Rio de Janeiro, 6 km (3.7 mi) from the discovery well (1-RJS-656, Iara), at a water depth of 2,197 m (7,208 ft).

This well, the fourth in the Iara area, is still undergoing the drilling stage and will continue with the aim of defining the base of the oil reservoirs. Results have confirmed 28° API oil in good quality carbonate reservoirs, obtained by cable samples, starting at a depth of 5,260 m (17,257 ft).

The consortium is going to proceed with the activities outlined in the evaluation plan approved by Brazil’s National Petroleum, Natural Gas and Biofuels Agency (ANP), which includes a formation test to assess the reservoir’s productivity.

Petrobras is the operator of the consortium (65%) in partnership with BG E&P Brasil (25%) and Petrogal Brasil/Galp Energia (10%).
