Petrobras has contracted drilling services for wells associated with its Cabiúnas–São Tomé carbon capture and storage pilot project in Rio de Janeiro, marking another step toward the operational deployment of CCS technology in Brazil.
The project is designed to capture CO₂ associated with natural gas processing in Cabiúnas and transport it for injection into an onshore saline reservoir in the São Tomé area.
The pilot is intended to validate technologies and monitoring techniques that could subsequently support larger-scale carbon storage projects. Earlier technical planning contemplated approximately 100,000 tonnes of CO₂ injection per year during the pilot phase.
Market Impact
The project may help establish a new service and infrastructure market involving:
- CO₂ capture facilities
- transportation infrastructure
- drilling and well services
- geological characterization
- injection and monitoring technologies
- environmental and integrity services
- specialized engineering and equipment
Successful implementation could provide technical foundations for larger CCS hubs serving oil and gas operations and hard-to-abate industries.
Legal & Regulatory Implications
Companies entering Brazil’s emerging CCS market should monitor:
- ANP authorization requirements
- environmental licensing
- ownership and transportation of captured CO₂
- injection and storage responsibilities
- monitoring and verification obligations
- long-term liability for storage sites
- allocation of leakage and environmental risks
The project is particularly significant because Brazil is moving from discussing CCS primarily as a regulatory concept toward testing the technology under actual operating conditions.
