In December 2021, Petrobras declared the commerciality of seven fields located on Sergipe-Alagoas deep waters: Agulhinha, Agulhinha Oeste, Budião, Budião Noroeste, Budião Sudeste, Cavala and Palombeta. The first oil is currently scheduled for a time-period between 2026 and 2028.
Among these fields, Budião also includes ONGC as part of the consortium, while Agulhinha and Cavala have iBV as a partner – which some news sources indicate that Bharat Petroleum seeks to purchase Videocon Oil Ventures’ share of these assets.
PGS recently requested a license for a potential new 3D project called PIRAMBU-NORTE, north of the studied areas. However, the blocks in the region were excluded from the latest Open Acreage Tender Protocol, recently published by ANP.
Most of Sergipe-Alagoas offshore production & development fields either are or were operated by Petrobras.
At shallow waters, Caioba, Camorim, Dourado, Guaricema and Salgo, are in the process of being relinquished. Paru (Origem) and Tartaruga (PetroReconcavo/Petrobras) are the only fields with production nowadays.
At deep regions, Piranema and Piranema Sul fields are also on relinquishment, having produced from 2008 to 2020.
All fields, with the exception of Paru and Tartaruga, halted their production in the beginning of 2020 due to the pandemic, and were not reactivated ever since.
The other deepwater and ultra deepwater fields, declared commercial in the end of 2021, are yet to be developed. Petrobras plans to install two FPSOs as part of production infrastructure.
Next to those fields are 8 exploration blocks, all operated by ExxonMobil in a consortium with Enauta and Murphy Oil. No discoveries were made on those yet, as the only well drilled by ExxonMobil in 2022 was dry.
The main petroleum system associated with these fields is the Late Cretaceous turbidites play. These turbidites are found between the Maastrichtian and Turonian horizons, interpreted by Geopost’s Content Team.
Agulhinha (60% Petrobras / 40% iBV), previously called Barra, was discovered in 2010 by wildcat 1-BRSA-851-SES at a water depth of 2,321m, which detected natural gas and condensate.
Cavala (60% Petrobras / 40% iBV), previously called Farfan, was discovered in 2012 by wildcat 1-BRSA-1083-SES, at a water depth of 2,720m, which detected a column of 44m with mostly porous sandstones containing light hydrocarbons.
Budião (75% Petrobras / 25% ONGC), previously called Poço Verde, also had positive results in 2019, when the appraisal 3-BRSA-1367-SES detected natural gas with a total thickness of 39m.
