Petrobras formation test in ultra-deep Sergipe-Alagoas Basin confirms excellent productivity of good quality oil

18 October 2013

Brazil’s Petrobras has completed a formation test on well 3-BRSA-1178D-SES (3-SES-176D), informally known as Farfan 1—the first well to evaluate the production capacity of the accumulation located in the BM-SEAL-11 concession area, block SEAL-M-426, in the ultra-deep waters of the Sergipe-Alagoas Basin. (Earlier post.)

The test evaluated 30 meters of turbidite sandstones formation and confirmed good reservoir characteristics featuring excellent productivity of good quality oil (38° API).

The well is 104 km (65 miles) off the city of Aracaju, some 5 km (3.1 miles) from the discovery well (BRSA-1083) and at a water depth of 2,476 meters (8,123 feet).

This formation test, conducted at a depth of 5,609 meters (18,402 feet), is a continuation of the operations carried out in the area as released to the market on 9 August Petrobras will proceed with other activities as soon as the Discovery Evaluation Plan submitted to Brazil’s National Petroleum, Natural Gas and Biofuels Agency (ANP) is approved.

Petrobras is the operator of the consortium (60%) in partnership with IBV-BRASIL (40%).
