Petrobras Notified Brazilian Authorities of Hydrocarbons Detection in a Pre-Salt Giant, New Perspectives Ahead
Petrobras notified Brazilian regulatory authorities after detecting hydrocarbons in Peroba, a giant pre-salt prospect where British BP and the China National Offshore Oil Corporation (CNODC) are partners. The asset, named 1-BRSA-1363-RJS, was drilled on October 24 by the deepwater drilling ship ODN II.
The ANP, Brazil’s oil regulatory body, estimates that Peroba holds around 5.3 billion barrels of oil in place. The public notification of any hydrocarbons detection in an exploration well does not, by itself, indicate commercial potential. However, expectations are high because Peroba was one of the most contested prospects in Brazil’s production sharing contract bidding round, in 2017, in the pre-salt province.
The consortium led by Petrobras bid for a government production share of 76.96%, along with a signing bonus set at 2 billion reais, equivalent to US $540 million. American ExxonMobil, Norway’s Equinor, China National Offshore Oil Corporation, and the largest Anglo-Dutch company Shell were among the losers.

The availability of high-quality 3D seismic data at Peroba and the pressure to justify a large signing bonus persuaded partners to move quickly into drilling operations.
BP holds a 40% stake in the project, with CNODC holding 20%.
Assets That Petrobras Transferred to CNODC
The Chinese oil subsidiary, CNODC, which belongs to China National Petroleum Corporation (CNPC), managed to acquire 20% of the Refining at Comperj from Petrobras and some fields in the Campos Basin, namely: Marlim, Voador, Marlim Sul and Marlim Leste, in all of these the share will also be 20%.
