Petrobras announced 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 percent stake while partner IBV Brasil has 40 percent.
The discovery took place during drilling of well 1-BRSA-1083-SES (1-SES-167), informally known as Farfan, at a water depth of 8,924 feet (2,720 meters).
At 68 miles (109 kilometers) from the municipality of Aracaju, the well is 13 miles (21 kilometers) 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 6 miles (10 kilometers) 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 144 feet (44 meters), of which 131 feet (40 meters) are formed by porous sandstones containing light hydrocarbons, was detected at a depth of 18,314 feet (5,582 meters).
Petrobras will proceed with well drilling up to a depth of 19,685 feet (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).
