Nanoparticle-CO2 foams: New methods for carbon storage and oil recovery via pore-scale microfluidics

该提案描述了纳米颗粒稳定的CO2泡沫的开发和测试，用于碳储存和使用微流体提高石油采收率。 其目的是通过将CO2包装到具有界面稳定纳米颗粒的泡沫中来实现孔级流动性控制。 3年交付成果是一种可用于灭火器的纳米颗粒-CO2泡沫，在稳定性和成本方面比现有技术（表面活性剂和聚合物驱油）有数量级的改进。 这项工作是通过基于微流体的开发，在油藏温度，压力和孔径下CO2泡沫性能的筛选和量化的新概念实现的。 这种方法将独特地使CO2泡沫稳定性、CO2储存、石油回收和成本在支持组织Apache Canada和Cenovus Energy（加拿大在CO2强化石油回收方面的世界领导者）采用之前能够量化。

This proposal describes the development and testing of nanoparticle-stabilized CO2 foam for carbon storage and enhanced oil recovery using microfluidics. The aim is pore-scale mobility control achieved by packaging CO2 into foams with interface-stabilizing nanoparticles. The 3-year deliverable is a reservoir-ready nanoparticle-CO2 foam with order of magnitude improvements over current technologies (surfactants and polymer floods) in terms of stability and cost. The work is enabled by the novel concept of microfluidics-based development, screening and quantification of CO2 foam performance at reservoir temperatures, pressures and pore sizes. This method will uniquely enable the quantification of CO2 foam stability, CO2 storage, oil recovery and cost as required before adoption by supporting organizations Apache Canada and Cenovus Energy - Canadian world leaders in CO2-enhanced oil recovery.
