Petrobras contracts Halliburton to drill four onshore wells for São Tomé CCS pilot
- Halliburton will drill and complete four onshore wells at Barra do Furado Station (EBAF) in Quissamã, Rio de Janeiro, under contract with Petrobras.
- The well set comprises one vertical injector and three directional monitoring wells for the São Tomé CCS pilot.
- The pilot aims to capture and store up to 100,000 tonnes of CO2 per year for three years, testing capture, pipeline transport and saline-reservoir storage.
- Drilling and infrastructure will be completed by 2028; operations start in 2029, followed by three years of injection and three years of reservoir monitoring.
Project scope
Petrobras has contracted Halliburton Produtos Ltda to drill and complete four onshore wells at the Barra do Furado Station (EBAF) in Quissamã, Rio de Janeiro. The wells—one vertical injector and three directional monitoring wells—are part of the São Tomé CCS pilot, the first project in Latin America to capture, move by pipeline and store CO2 from industrial sources in a saline reservoir.
Schedule and targets
The pilot is designed to capture up to 100,000 tonnes of CO2 per year for a three-year injection phase. Drilling and completion of the wells together with required infrastructure are scheduled for completion by 2028; operations will begin in 2029, followed by three years of injection and three years of reservoir monitoring.
Technology and regulatory testing
The initiative is an R&D&I project intended to validate technologies and inform regulatory frameworks. Innovations include fibre-optic monitoring for real-time CO2 plume tracking, a reservoir sampling system that avoids well intervention, CO2-resistant materials, and fiberglass-coated monitoring wells to enable nuclear magnetic resonance data acquisition. The project will provide a real-world basis for ANP and INEA to monitor and validate CCS procedures and norms.
