Petrobras Finds New Oil Reserves in Brazil's Campos Basin Area

By Zacks Equity Research | November 18, 2025, 8:44 AM

Petrobras PBR, the Brazilian integrated oil and gas company, recently made a significant offshore oil discovery, adding to the country's growing momentum in deepwater exploration. This discovery, located in the Campos Basin off Brazil’s southeastern coast, highlights the company’s continued dominance in offshore oil exploration and its focus on mature deepwater fields. According to World Oil, the company confirmed the find of high-quality post-salt crude at the Sudoeste de Tartaruga Verde block, supporting Brazil’s position as a leader in global oil exploration.

Petrobras’ Latest Discovery: A Milestone in Offshore Exploration

The discovery occurred at well 4-BRSA-1403D-RJS, situated 108 km offshore from the city of Campos dos Goitacazes, within a water depth of 734 meters. This depth indicates that Petrobras has once again succeeded in exploring areas with significant technical challenges, a testament to its expertise in deepwater drilling.

The company confirmed that drilling at the site has now been completed, with the oil-bearing interval verified through a combination of electrical logs, gas readings and fluid sampling. These data will be crucial in assessing the full scope of the discovery and informing the next stages of exploration and development.

Importance of Laboratory Analysis for Future Development

To better understand the characteristics of the reservoir, Petrobras will send samples from the well for laboratory analysis. This process will help the company characterize the reservoir’s properties and fluid composition, which are essential for determining the potential of the field. The analysis will guide the next steps in Petrobras’ appraisal and development planning, providing insights into how best to exploit the new discovery for optimal production. The results will also help Petrobras forecast potential recovery rates and plan future drilling operations.

Sudoeste de Tartaruga Verde Block: A Strategic Asset

The Sudoeste de Tartaruga Verde block was awarded to Petrobras during Brazil’s 5th Production Sharing Round in 2018. This block is strategically significant for the company, as it is part of the broader effort to explore and develop offshore fields in the Campos Basin. Petrobras holds a 100% operating interest in the block, making this discovery an essential addition to its portfolio. The block itself is managed by Pré-Sal Petróleo S.A., the Brazilian state-run company responsible for overseeing the country’s oil and gas assets.

Petrobras’ success in this area is indicative of the dominance in Brazil’s offshore oil industry, where it has long held a leadership position. This discovery marks another significant step in Petrobras’ ongoing efforts to enhance its exploration activities, focusing not only on presalt resources but also on post-salt formations, which are becoming increasingly important in the region’s oil and gas sector.

Impact on Brazil’s Offshore Oil and Gas Sector

This latest discovery further cements Brazil’s position as a leading player in global offshore exploration. Over the past decade, Brazil has seen a series of major offshore oil finds, many of which have been in the Campos Basin, an area that continues to yield high-quality reserves. Petrobras’ continued success in this region speaks of its expertise in operating in some of the world’s most challenging deepwater environments. These discoveries have also contributed significantly to the country’s economic growth, as Brazil continues to be a major exporter of oil, particularly to international markets.

Moreover, this new find is part of a broader strategy by Petrobras to diversify the exploration activities beyond the presalt, an area that has long been the focus of its efforts. By identifying and developing post-salt crude reserves, Petrobras is positioning itself to capitalize on a broader range of oil and gas resources, bolstering the future production capacity and extending the life of Brazil’s offshore oil fields.

Strengthening Petrobras’ Resource Pipeline

Petrobras’ exploration success in Brazil is not just a win for it — this also reinforces the country’s growing reputation as a hub for offshore oil exploration. The discovery at the Sudoeste de Tartaruga Verde block adds to a series of recent exploration successes across Brazil’s offshore basins, signaling strong potential for continued growth in the sector. This is particularly significant in the context of global energy markets, where demand for oil and gas remains strong, and where companies are increasingly looking for new reserves to sustain production levels.

For Petrobras, the discovery further strengthens its near to mid-term resource pipeline, giving it the flexibility to expand the portfolio of producing assets. As the company continues to explore and develop Brazil’s offshore resources, it is well-positioned to remain a dominant force in the global energy landscape.

Conclusion

The confirmation of another significant oil discovery by Petrobras highlights its enduring strength in offshore oil exploration and the critical role in Brazil’s energy sector. With its ongoing successes in the Campos Basin and beyond, Petrobras continues to set the stage for long-term growth, adding valuable reserves to its portfolio. As the company moves forward with its development plans, the future looks bright for both Petrobras and Brazil’s offshore oil industry.
