Sergipe-Alagoas Basin

Located on the continental margin of the Northeast region of Brazil, the Sergipe-Alagoas Basin covers part of the states of Sergipe and Alagoas.  The basin has a total area of , of which is onshore and is in the sea portion, at a bathymetric elevation of . The Basin is bounded on the North by the Pernambuco-Paraíba Basin and the on the South by the Jacuípe Basin. The basin produced per day of oil and gas in the first half of 2015 was, with an average of 32 fields in activity during this period.


Sergipe-Alagoas occupies an increasingly prominent position among Brazilian basins due to its high geological success rate, with seven discoveries in ultra-deep waters reported during the first half of 2015 in blocks from the 6th Bidding Round. Seven evaluation plans have been submitted to the ANP, including the Moita Bonita, Barra and Farfan Plans. The plans account for six accumulations in the Early Cretaceous turbidite sandstones and one in the Aptian reservoirs of the Muribeca Formation.

In 1935, exploratory activities began in the Basin with geophysical surveys and the drilling of the 2-AL-1 well, led by the National Petroleum Council (“Conselho Nacional do Petróleo”). The first commercial oil discovery occurred in 1957, at the TM-1 AL-well. 11 years later, Brazil celebrated the first offshore oil discovery, with the discovery of the Guaricema Field, which has been producing oil since 1973. In 2007, the basin reached another milestone, with the beginning of production of light oil in deep waters in the Piranema Field.

Approximately six thousand wells have been drilled to date in the Sergipe-Alagoas Basin, and about 10% are located offshore. Total hydrocarbons reserves in the Basin are approximately 410 million bbl of oil and of gas, according to 2014 data from the National Agency of Petroleum, Natural Gas and Biofuels (“Agência Nacional do Petróleo, Gás Natural e Biocombustíveis” - ANP).


Blocks SEAL-M-351 and SEAL-M-428

In the ANP’s 13th Bidding Round, QGEP acquired 100% ownership and operatorship of two concessions located in the Sergipe-Alagoas Basin: SEAL-M-351 and SEAL-M-428 blocks, with total area of .

The identified prospects are post-salt and the main reservoirs to date are turbidite sandstones of the Early Cretaceous. The blocks are located between and off the coast, in ultra-deep waters, with water depths ranging from to . They are bordered to the West by blocks with reported discoveries of light oil of excellent quality, which are in the delimitation stage. The expected fluid in the region is predominantly light oil.

QGEP paid a total of R$100.0 million in signature bonuses for participation in the two exploratory blocks: R$63.9 million for Block SEAL-M-351 and R$36.1 million for Block SEAL-M-428, both values equivalent to the minimum bonus required in the bid. Under the minimum exploratory program (“Programa Exploratório Mínimo” - PEM) signed with the ANP, QGEP committed to perform 3D seismic acquisition for the two blocks, to be carried out in the next five years with estimated CAPEX of US$15-20 million. Regarding local content, for both blocks, QGEP offered 37% in the exploration phase and 55% in the development phase.
