石油和凝析油以及天然气分别占总量的 84% 和 16%。

2025年，巴西石油公司（Petrobras）继续保持显著的储量增长（17亿桶油当量），专注于为社会和股东创造价值，致力于保障国家可持续发展和公正能源转型所需的能源安全。即使在2025年创下年产量纪录之后，储量替代率（RRR）仍高达175%。已探明储量与产量之比（R/P）为12.5年。

储量增加主要归功于资产的出色表现，特别是桑托斯盆地的Bzios、Tupi、Itapu和Mero油田，以及塞尔希培-阿拉戈斯盆地深水区的Budi-so、Budi-so Noroeste和Budi-so Sudeste油田的开发进展，以及桑托斯盆地和坎波斯盆地Bzios、Tupi、Marlim Sul和Jubarte油田的新井开采。油价波动并未造成显著影响，凸显了我们项目的韧性。

图表显示了已探明储量的演变过程。

总和上的明显差异是由于四舍五入造成的。[1] 未考虑以下因素：(a) 天然气凝析液，因为除美国和阿根廷外，其储量是在天然气加工前的参考点估算的；(b) 注入天然气的量；(c) 勘探区块中长期井测试的产量；以及 (d) 玻利维亚的产量，因为玻利维亚宪法不允许公司登记储量。

考虑到未来几年的预期产量，必须继续投资，最大限度地提高已发现资产的采收率，探索新的领域，并使巴西国内外的勘探组合多元化，以替代石油和天然气储备。

根据美国证券交易委员会（SEC）的规定，巴西石油公司已将其超过90%的已探明储量提交给独立的第三方机构进行评估。目前，这项评估由德戈耶和麦克诺顿公司（D&M）负责。

巴西石油公司（Petrobras）也根据巴西国家石油、天然气和生物燃料管理局/石油工程师协会（ANP/SPE）的定义估算储量。截至2025年12月31日，根据这些定义，已探明储量达到125亿桶油当量。ANP/SPE定义估算的储量与根据美国证券交易委员会（SEC）规定估算的储量之间的差异，主要源于不同的经济假设，以及ANP储量规定允许将巴西油田特许经营期结束后预计生产的产量计入储量。

Oil and condensate, and natural gas correspond to 84% and 16% of this total, respectively.

In 2025, Petrobras followed the trajectory of significant reserves addition (1.7 billion boe), maintaining focus on providing value for the society and shareholders, pursuing energy security for the country's sustainable development and for a just energy transition. The reserve replacement rate (RRR) was 175%, even after a record annual production in 2025. The proved reserves-to-production ratio (R/P) is 12.5 years.

The reserves addition occurred mainly due to the outstanding performance of the assets, with emphasis on Búzios, Tupi, Itapu and Mero fields in Santos Basin, to the progress in the development of Budião, Budião Noroeste and Budião Sudeste fields in the deep waters of Sergipe-Alagoas Basin, and to new wells mainly in Búzios, Tupi, Marlim Sul and Jubarte fields in Santos and Campos basins. There were no relevant changes related to the variation in the oil price, highlighting the resilience of our projects.

The evolution of proved reserves is shown in the graph.

Apparent differences in sums are due to rounding. [1] Does not consider: (a) natural gas liquids, since the reserve is estimated at a reference point prior to gas processing, except in the United States and Argentina; (b) volumes of injected gas; (c) production from extended well tests in exploration blocks; and (d) production in Bolivia, since the Bolivian Constitution does not allow the registration of reserves by the company.

Considering the expected production for the coming years, it is essential to continue investing in maximising the recovery factor of already discovered assets, exploring new frontiers and diversifying the exploratory portfolio in Brazil and abroad to replace oil and gas reserves.

Petrobras has submitted more than 90% of its proved reserves, as defined under SEC regulations, to independent third-party evaluation. Currently, this evaluation is conducted by DeGolyer and MacNaughton (D&M).

Petrobras also estimates reserves according to the ANP/SPE (National Agency of Petroleum, Natural Gas and Biofuels / Society of Petroleum Engineers) definitions. As of December 31, 2025, the proved reserves according to these definitions reached 12.5 billion boe. The differences between reserves estimated by ANP/SPE definitions and those estimated using SEC regulation are mainly due to different economic assumptions and the possibility, under ANP reserves regulations, of recognising as reserves the volumes expected to be produced beyond the concession term in Brazilian fields.
