In the Sururu field, Petrobras increased its stake to 45.394 percent from an original 42.5 percent. Shell’s participation decreased to 23.742 percent from 25 percent, while TotalEnergies now holds 21.367 percent compared to 22.5 percent previously. Petrogal’s share dropped to 9.497 percent from 10 percent. The Berbigão field saw more dramatic consolidation, with Petrobras’s stake rising to 62.913 percent. Shell retains 16.125 percent, TotalEnergies 14.512 percent, and Petrogal 6.450 percent in that reservoir.
The balancing agreements reconcile production revenues, capital expenditures, operating costs, and oil royalties proportional to each partner’s adjusted interest. The financial settlement covers the period from September 15, 2000, when the BM-S-11 concession contract was signed, through April 30, 2026, the day before the production individualization agreements took effect. The $859 million net payment to Petrobras reflects adjustments across these accounting categories over the 26-year operational history.
The Sururu and Berbigão shared reservoirs comprise both the BM-S-11-A concession agreement and a separate transfer of rights contract where Petrobras already held 100 percent before the recent restructuring. The Santos Basin fields represent strategic pre-salt assets in Brazil’s offshore portfolio. The consolidation strengthens Petrobras’s operational leverage in one of the country’s most productive hydrocarbon provinces while providing immediate cash flow from consortium partners compensating for historical cost imbalances and the adjusted ownership structure going forward.
