Petrobras informs about another oil discovery in the Campos Basin

—

Rio de Janeiro, November 17, 2025 –Petróleo Brasileiro S.A. – Petrobras informs that it has identified the presence of excellent quality oil in the pos-sal of the Campos Basin, in an exploratory well in the Sudoeste de Tartaruga Verde block.

Well 4-BRSA-1403D-RJS is located 108 km from Campos dos Goytacazes-RJ city shore, at a water depth of 734 meters. The drilling of this well has ended, with an oil-bearing interval confirmed through electrical logs, gas shows, and fluid sampling.

These samples will subsequently be sent for laboratory analyses, which will enable the characterization of reservoir and fluid conditions found, allowing for the continuation of the area's potential evaluation.

The Sudoeste de Tartaruga Verde block was acquired in September 2018, during the 5th Production Sharing Round, with Pré-Sal Petróleo S.A. (PPSA) as the manager. Petrobras is the operator of the block
