Sergipe-Alagoas Basin

Continental Margin

Water depth:

up to 4,000 meters

Expected fluid:


We have 30% stake in SEAL-M-351, SEAL-M-428, SEAL-M-430, SEAL-M-501, SEAL-M-503, SEAL-M-505, SEAL-M-573, SEAL-M-575 and SEAL-M-637.


Throughout 2020 the Consortium evaluted the 3D seismic data from the first six blocks – processing of the definitive data was completed in Q2 2020. The first exploratory well to be drilled will be in the Cutthroat prospect, located in SEAL-M-428.


The environmental licensing application for drilling operations is in progress, and the EIA/RIMA has already been filed by the Operator with IBAMA. Drilling should start before the end of 2021.


Region with high potential for discoveries


The Sergipe-Alagoas Basin is located on the continental margin of the northeast region of Brazil, covering part of the states of Sergipe, Alagoas and a small portion of the state of Pernambuco. It has a total area of about 44,000 km², of which approximately 32,000 km² offshore up to the bathymetric quota of 3,000 m and 12,000 km² onshore. It is bordered to the north by the Pernambuco-Paraiba Basin and to the south by the Jacuípe Basin.


Since 2007, new frontiers have been opened by the industry, starting the production of light oil in deep waters. The basin is increasingly prominent due to its high rate of geological success, with discoveries in ultra-deep waters.


The market estimates that deepwater discoveries in the region exceed 1.2 billion boe.



Characteristics: high potential recoverable volume, logistical facilities, medium to low risk prospects. Long-term test in Farfan by Petrobras in 2018. Expectation of light oil, 30-40˚API.
