| In 2023 we standardize the conversion between gas and oil equivalent to 5,614.65 ft3 = 1 boe, equivalent to the conversion used in contracts in Brazil. The quantities from previous years are restated with the new conversion. |                       |                      |                         |                       |     |                         |     |       |

The natural gas production presented in these tables is the
volume extracted from our proved reserves, including gas consumed in operations and excluding reinjected gas. Our disclosed proved gas
reserves include volumes of gas consumed, which represent 36% of our total proved natural gas reserves in 2024.

The tables below summarize information on changes in proven
oil and gas reserves, in millions of barrels of oil equivalent, of our consolidated and equity-invested entities for 2024, 2023 and 2022:
