New discovery of hydrocarbons in ultra-deep waters of the Sergipe-Alagoas Basin
Petrobras announces that it has confirmed the presence of light hydrocarbons in block SEAL-M-426, in ultra-deep waters of Sergipe-Alagoas Basin. This block is part of concession BM-SEAL-11, where Petrobras is the operator with a 60% stake while partner IBV Brasil has 40%.
The discovery took place during drilling of well 1-BRSA-1083-SES (1-SES-167), informally known as Farfan, at a water depth of 2,720 meters.
At 109 km from the municipality of Aracaju, the well is 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. In this same Basin, on 08/22, Petrobras announced the completion of the Barra extension well, 3-BRSA-1069-SES (3-SES-165 – Barra 1) which also found oil and is located 10 km northwest of the Farfan well.
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 hydrocarbon column of 44 meters, of which 40 meters are formed by porous sandstones containing light hydrocarbons, was detected at a depth of 5,582 meters.
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 (ANP).
