This study investigates CO2 injection in the Norne reservoir, focusing on static and dynamic modeling to assess long-term carbon storage potential. The research employs a comprehensive approach, integrating geological data into a static model, which serves as the foundation for dynamic simulations spanning a 15-year injection period followed by a 100-year shut-in phase. The static model captures the Norne field's complex geology, incorporating structural and stratigraphic features, porosity, and permeability distributions. Dynamic simulations built upon this model account for multiphase flow. Results demonstrate significant CO2 plume migration during the injection phase, with preferential flow through high-permeability zones. Post-injection behavior reveals gradual CO2 stabilization, with increasing contributions from residual and solubility trapping over time.
