这项研究将二氧化碳强化采油 (EOR) 方法与地下封存策略相结合，以实现二氧化碳的永久封存，同时提高油藏的经济效益。该研究开发了一种采用多目标优化技术的新型工作流程，以评估在咸水层中实现二氧化碳永久地质封存的压力管理方法的整合效果。
油藏模型描述。为配合本项目，我们采用非等温建模程序构建了一个代表墨西哥湾典型地层的均质油藏模型。该模型以页岩层为特征，将油藏与含水层分隔开来，从而可以同时评估二氧化碳提高采收率(EOR) 和二氧化碳封存。该模型采用 EOS-PVT E300 模拟器，在多组分体系下进行设计。
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.
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.
