This project aims to develop an efficient multi-scale laboratory-based modelling framework for the analysis of nonequilibrium transport and reaction processes occurring in CO2 storage scenarios. In a significant technological advance two non-destructive analysis techniques, Xray computed tomography and nuclear magnetic resonance, are combined with pore-scale simulations to address uncertainties in dynamic wettability alteration occurring during gravity driven convection. Expected outcomes are the in-situ characterisation of solid-surface interactions and predictions of multi-phase fluid flow. The project benefits the Australian resources sector by improving injectivity, storage efficiency and security of supercritical CO2 storage projects.

该项目旨在开发一个有效的多尺度实验室建模框架，用于分析CO2储存情景中发生的非平衡迁移和反应过程。在一个显着的技术进步，两个非破坏性的分析技术，X射线计算机断层扫描和核磁共振，结合孔隙规模的模拟，以解决在重力驱动的对流过程中发生的动态润湿性改变的不确定性。预期的成果是在现场表征固体表面的相互作用和预测的多相流体流动。该项目通过提高超临界CO2储存项目的注入能力、储存效率和安全性，使澳大利亚资源部门受益。
