CO2 geological storage

Project outline

A feasibility assessment for geological CO₂ storage in an offshore reservoir near a major CO₂ producer, such as a refinery, has been conducted.

1. Data Collection and Reservoir Analysis
   • Geological, geophysical, and petrophysical data were gathered and analyzed.
   • Seismic interpretation and well-log analysis defined structural traps and reservoir properties.
2. Reservoir Characterization
   • Porosity, permeability, and cap rock integrity were assessed.
   • Potential leakage pathways and seal effectiveness were evaluated.
3. Dynamic Simulation and Injection Modeling
   • CO₂ injection simulations predicted plume migration and storage capacity.
   • Pressure buildup and risks of induced seismicity were evaluated.
4. Risk Assessment and Monitoring
   • Environmental and operational risks were identified.
   • A monitoring framework using seismic surveys and pressure sensors was developed.
5. Economic and Regulatory Review
   • Cost estimation for injection, monitoring, and storage was performed.
   • Compliance with national and international CO₂ storage regulations was ensured.
6. Integration with CO₂ Source
   • Transport logistics from the refinery to the offshore site were evaluated.
   • Injection strategies were optimized for efficiency and sustainability.

The study confirmed the reservoir’s potential for safe and efficient CO₂ storage, supporting climate mitigation efforts.
