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二氧化碳泡沫的开发和测试，用于碳储存和使用微流体提高石油采收率。其目的是通过将二氧化碳包装到具有界面稳定的纳米颗粒的泡沫中来实现孔规模的流动性控制。3年的可交付产品是一种可供油藏使用的纳米颗粒-二氧化碳泡沫，在稳定性和成本方面比目前的技术(表面活性剂和聚合物驱)有数量级的改进。这项工作得益于基于微流体的开发新概念，筛选和量化了在油藏温度、压力和孔隙大小下的二氧化碳泡沫性能。这种方法将独一无二地实现二氧化碳泡沫稳定性、二氧化碳储存、石油采收率和成本的量化，这是支持组织-加拿大阿帕奇和Cenovus Energy-加拿大在二氧化碳强化石油回收方面的世界领先者所要求的。

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.
