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

本提案描述了纳米颗粒稳定的二氧化碳泡沫的开发和测试，用于微流体的碳储存和提高石油采收率。其目的是通过使用界面稳定纳米颗粒将二氧化碳封装到泡沫中来控制孔隙尺度的迁移率。该项目将在3年内开发出一种可用于储层的纳米颗粒- 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）有了数量级的改进。这项工作是由基于微流体的开发、筛选和量化油藏温度、压力和孔隙尺寸下CO2泡沫性能的新概念实现的。该方法可以在支持Apache Canada和Cenovus Energy（加拿大二氧化碳提高采收率领域的世界领导者）采用之前，根据需要对CO2泡沫稳定性、CO2储存、石油采收率和成本进行量化。

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.
