Asset Revitalization, Operational Efficiency, and New Operators Drive Production in Mature Fields in Brazil
The revitalization of mature oil and gas fields will be one of the central themes of Macaé Energy 2026, an event that will take place from March 17 to 19, 2026, at the Jornalista Roberto Marinho Convention Center in Macaé, bringing together companies, executives, and experts from the energy industry.
The discussion about mature fields has gained momentum in recent years with the shift in the profile of the Brazilian oil and gas industry, especially after the decision by Petrobras, starting in 2019, to sell various assets considered non-strategic in onshore and offshore basins.
This movement created space for new independent companies, which began to invest in the revitalization of these assets with a focus on operational efficiency and new production technologies.
-
The largest South American oil company, Petrobras, is preparing for a historic leap in production with new FPSO platforms and the expansion of refining — projects that could add up to 900,000 barrels per day and strengthen Brazil’s energy security.
-
Billions of barrels in the Equatorial Margin could double Amapá’s oil production in Brazil and attract companies from the Campos Basin.

Offshore And New Investment Opportunities Will Be At The Center Of Discussions At Macaé Energy 2026

Oil And Gas Supply Chain Gains Prominence And Will Be A Strategic Topic At Macaé Energy 2026
According to data released by the National Agency of Petroleum, Natural Gas and Biofuels (ANP) in 2024, more than 40 mature offshore and onshore fields were transferred to independent operators in Brazil in the last five years.
Independent Companies Expand Presence in Production
With the sale of Petrobras assets, several companies have begun to operate in the revitalization of mature fields.
Among the main operators that have expanded their presence in this segment are:
• PRIO (PetroRio)
• 3R Petroleum
• Brava Energia
• Perenco
• PetroReconcavo
These companies have started to operate fields that were previously under Petrobras management, implementing new management models and investments focused on production recovery.
One of the best-known examples is the Frade Field, in the Campos Basin, operated by PRIO, which managed to increase production after taking over the asset.
According to data released by the company itself in 2024, the field’s production exceeded 30,000 barrels of oil per day after investments in operational optimization.
Another relevant case is the Papa-Terra Field, also in the Campos Basin, which began to be operated by 3R Petroleum in partnership with Petrobras after an agreement announced in 2023.
Technologies Increase Oil Recovery
One of the main strategies for revitalizing mature fields involves the use of new technologies to increase the oil recovery factor.
According to studies by the Energy Research Company (EPE) released in 2023, many mature fields in Brazil still have significant volumes of oil that can be produced using modern technologies.
Among the solutions used in revitalization are:
• water injection to maintain reservoir pressure
• natural gas or CO₂ injection
• drilling of new horizontal wells
• 3D and 4D seismic reprocessing
• digital monitoring of reservoirs
According to estimates from the Brazilian Institute of Oil and Gas (IBP) published in 2024, technological improvements can increase the recovery factor of mature fields by up to 10% or 15%, which represents billions of additional recoverable barrels.
Campos Basin Continues to Be a Revitalization Laboratory
The Campos Basin, located on the coast of the state of Rio de Janeiro, continues to be one of the main hubs for revitalizing mature fields in the country.
This region has been responsible for a large part of the national oil production since the 1980s, when giant fields such as Marlim, Albacora, Roncador, and Barracuda were discovered.
With the advancement of pre-salt in the Santos Basin, many of these assets have been classified as mature fields, creating room for new management models.
According to data released by Petrobras in 2024, revitalization projects in Campos Basin fields still have the potential to recover billions of barrels of oil in the coming decades.
This process involves the installation of new platforms, modernization of equipment, and restructuring of offshore operations.
Mature Fields Also Generate Opportunities for Suppliers
The revitalization of mature fields also stimulates the entire supply chain of the oil and gas industry.
Projects of this type require services and equipment such as:
• maintenance and modernization of platforms
• asset inspection and integrity
• engineering and drilling of new wells
• offshore logistics
• digital solutions for production monitoring
According to a survey released by the ONIP (National Organization of the Oil Industry) in 2024, revitalization projects can generate thousands of direct and indirect jobs in the productive chain of the energy sector.
Cities like Macaé, a historical logistics base of the Campos Basin, continue to play a strategic role in executing these activities.
Mature Fields Will Be at the Center of Discussions at Macaé Energy 2026
During Macaé Energy 2026, industry experts and executives are expected to discuss the future of mature fields in Brazil, including new exploration models, opportunities for independent operators, and technologies applied to asset revitalization.
Among the topics expected in the panels are:
• operational efficiency in mature fields
• revitalization of offshore assets
• new oil recovery technologies
• opportunities for suppliers in the productive chain
• management models adopted by independent companies
The discussion gains relevance at a time when Brazil seeks to expand its oil production while maintaining the competitiveness of the energy industry.
How to Participate in Macaé Energy 2026
Professionals, companies, and those interested in following the debates on the future of the energy industry can register on the official event website.
Registrations for Macaé Energy 2026 are available at the official address: https://macaeenergy.com.br/
The event will take place from March 17 to 19, 2026, bringing together executives, experts, and companies from the oil, gas, and energy productive chain to discuss investments, market trends, and new business opportunities.
