Petrobras makes another discovery of hydrocarbons in Sergipe-Alagoas Basin’s ultra-deepwaters

Posted on 11 October 2012

Light hydrocarbons were found in ultra-deepwaters of the Sergipe-Alagoas Basin at a water depth of 2,720 meters.

Petrobras has confirmed the presence of light hydrocarbons in ultra-deepwaters of the Sergipe-Alagoas Basin. The discovery took place during drilling of the Farfan well at a water depth of 2,720 meters.

The well is 109 km from the municipality of Aracaju and 21 km southeast of the Barra accumulation, where well 1-BRSA-851-SES (1-SES-158 – Barra) was drilled, which revealed the first significant gas discovery in ultra-deep waters of the Sergipe-Alagoas Basin.

The discovery of Farfan was confirmed by traces of oil detected during well drilling, electric log analysis and fluid samples collected from cable tests.

A 44-meter hydrocarbon column, of which 40 meters are formed by porous sandstones containing light hydrocarbons, was detected at a depth of 5,582 meters.

In the same basin, Petrobras completed the Barra extension well, 3-BRSA-1069-SES (3-SES-165 – Barra 1) in August, which also held oil and is located 10 km northwest of the Farfan well.

Block SEAL-M-426, where the discovery was found, is part of concession BM-SEAL-11, where Petrobras is the operator with a 60% stake while partner IBV Brasil has 40%.

Petrobras will proceed with well drilling up to a depth of 6,000 meters and will analyze the rocks and fluids obtained from this well with the aim of submitting the Appraisal Plan to the National Petroleum, Natural Gas and Biofuels Agency.
