§Winston Score History

The full picture

Prio S.A. is a Brazilian oil and gas company that finds and produces crude oil, mainly from offshore fields in the Campos and Santos basins along Brazil's coast. It focuses on acquiring mature oil fields from larger companies and then improving their output using modern techniques. Prio is one of the largest independent oil producers in Brazil.

The company makes money by selling crude oil on international markets. It operates exclusively in Brazil and has grown quickly by buying underperforming assets and boosting their production at relatively low cost. This acquisition-driven strategy, combined with lean operations, gives Prio a cost advantage over many peers. Key growth depends on successfully integrating new field acquisitions and expanding production, while the main risks include volatile global oil prices and the regulatory environment for offshore drilling in Brazil.
