Obs:

  1. Frade figures account for a 70% interest in the Frade Field until February 4 and 100% interest as of February 5, when the Company announced the closing of the acquisition of the remaining 30% interest.
  2. On November 5, 2020, the sale of the 10% interest in the Manati Field held by PetroRio was announced, which awaits precedent conditions for the transaction's closing.
  3. Tubarão Martelo Field production in March was impacted by a shutdown in the TBMT-8H well due to a failure in the electrical submersible pump (ESP), which decreased production by 1,4 kbbld. The pump, which was operating since the beginning of the field's production, awaits the Atlantic Zephyr rig (renamed to Kingmaker) deployment to carry out a workover, expected to be concluded in May/June.
