 894 million boe. Production refers to volumes
that were previously included in our reserves and, therefore, does not consider natural gas liquids, since the reserve is estimated at
a reference point prior to gas processing, except in the United States of America and Argentina. The production also does not consider
volumes of injected gas, the production of Extended Well Tests in exploratory blocks and production in Bolivia, since the Bolivian Constitution
does not allow the registration of reserves by the Company.

| SUPPLEMENTARY INFORMATION (Unaudited)PETROBRAS(In millions of reais, unless otherwise indicated) |

In 2022, we incorporated 1,989 million boe of proved reserves
by revising previous estimates, including:

(i) addition of 1,279 million boe due to new projects, mainly
in Búzios field and in other fields in the Santos and Campos Basins; and

(ii) addition of 710 million boe arising from other revisions,
mainly due to good performance of reservoirs in the pre-salt layer of Santos Basin and to the contract term extension of Rio Urucu and
Leste do Urucu fields. We did not have relevant changes related to the variation in the oil price.

The addition in our proved reserves were partially offset
by the reduction of 536 million boe, due to the effects of the transfer of interests of 5% of the Surplus Volume of the Transfer of Rights
of Búzios field, of the write-offs related to the Co-Participation Agreements of Atapu and Sepia fields and of sales of properties
in mature fields.

The Company's total proven reserve in 2022 resulted in 10,473
million boe, considering the incorporations, reviews and assignments of rights described above and discounting the year's production of
860 million boe. This production refers to volumes that were included in our reserves and, therefore, does not consider natural gas liquids,
since the reserve is estimated at a reference point prior to gas processing, except in the United States and Argentina. Production also
does not consider volumes of injected gas, the production of long-term tests in exploratory blocks and production in Bolivia, since the
Bolivian Constitution does not allow the recording of reserves.

The tables below present the volumes of proved developed and
undeveloped reserves, net, that is, reflecting Petrobras' participation:
