Petrobras Confirms Oil near Espirito Santo

Petrobras announced that extension well 3-BRSA-1128-ESS, whose objective is to delineate the accumulation, has confirmed the presence of light oil and gas in sandstones reservoirs in the post-salt of Espírito Santo Basin. Discovery of the accumulation had already been announced December 17, 2010, when well 1-BRSA-882-ESS, known as Indra, was drilled.

The new well, informally known as Arjuna, is part of the 1-BRSA-882-ESS (Indra) Evaluation Plan, and is about 81 miles (130 kilometers) off the coast of Espírito Santo state and .6 miles (.9 kilometers) northwest of the discovery well.

The oil reservoirs, whose age ranges from the Paleocene to the Santonian, have a total thickness of some 656 feet (200 meters) and are approximately 12,070 feet (3,679 meters) deep, at a water depth of 7,031 feet (2,143 meters).

A formation test will be carried out to assess the productivity of the reservoir. As verified in the discovery well, the oil found is of good quality (29 degree API).

The consortium of concession BM-ES-22A (Block ES-M-527), made up by Petrobras (75%), as operator, and Vale (25%), will proceed with the activities and investments set out in the Discovery Evaluation Plan (PAD), approved by Brazil’s National Petroleum, Natural Gas and Biofuels Agency (ANP).
