Business context and reporting period
Petrobras filed this Form 6-K in October 2026, reporting that it signed cost and volume balancing agreements with Shell, TotalEnergies and Petrogal for the Berbigão and Sururu shared reservoirs in Brazil’s Santos Basin. The balancing period runs from September 15, 2000, through April 30, 2026.
Financial and operational highlights
- Petrobras expects to receive a net amount of approximately US$859 million from its BM-S-11A consortium partners, with settlement due by November 2026.
- The filing does not provide a clear breakdown of the amount by partner, reservoir, or accounting category, or quantify any effect on revenue, profit, cash flow, margins, debt or liquidity.
- The agreements reconcile production revenues, investment expenditures, operating expenditures and oil royalties according to the parties’ interests in the shared reservoirs.
Interests and changes
Following ANP approval of the production individualization agreements, the interests in the shared reservoirs are:
| Partner | Sururu | Berbigão |
|---|---|---|
| Petrobras | 45.394% | 62.913% |
| Shell | 23.742% | 16.125% |
| TotalEnergies | 21.367% | 14.512% |
| Petrogal | 9.497% | 6.450% |
These allocations differ from the BM-S-11A concession interests: Petrobras 42.5%, Shell 25%, TotalEnergies 22.5% and Petrogal 10%. Petrobras also holds 100% of the Transfer of Rights agreement. The new configuration establishes proportional interests in the shared reservoirs.

The expected US$859 million receipt is a one-time balancing settlement described in this filing; no broader financial guidance or operating outlook is provided. Petrobras’ standard forward-looking-statement warning notes that forecasts involve risks and uncertainties and actual results may differ from expectations.
