This work combines CO2-enhanced oil recovery (EOR) methods with subsurface containment strategies to permanently store CO2 while simultaneously increasing cost-effective oil production from reservoirs. The study develops a novel workflow with multiobjective optimization techniques to assess the integration of pressure-management methodologies for permanent geological CO2 storage in saline aquifers.
Methodology
Reservoir Model Description. A homogeneous reservoir model, representative of typical Gulf of Mexico formations, was constructed using a nonisothermal modeling code for the purpose of the project. The model features a shale layer separating an oil reservoir from an aquifer, allowing the assessment of simultaneous CO2-EOR and CO2 sequestration. The model was designed under a compositional multicomponent system using the EOS-PVT E300 simulator.
