Equinor (formerly Statoil) has completed transactions covering two major deepwater oilfields in the Campos basin. One, valued at up to $2.55 billion, gives the company a 25% share of Petrobras’ license over the Roncador field, and associated production of around 60,000 boe/d. The company plans to apply its IOR experience offshore Norway to help Petrobras lift remaining recoverable volumes from 1 Bboe to 1.5 Bboe.

The other deal entailed transferring 39% of the BM-S-8 block containing the Carcará field to ExxonMobil and Galp. The same partners are present in the adjoining Carcará Norte block and now have full control over the unitized field which is thought to hold over 2 Bboe recoverable. After firming up the resource potential of the area, planning will start on development, with Equinor targeting first oil during 2023-24.
