Physico-chemical effects on long-time fluid transport for CO2 geostorage

该项目旨在开发一个有效的、以实验室为基础的多尺度模拟框架，用于分析二氧化碳储存情景中发生的非平衡传输和反应过程。在一项重大的技术进步中，两种非破坏性分析技术--X射线计算机断层扫描和核磁共振--与孔隙尺度模拟相结合，以解决重力驱动对流过程中发生的动态润湿性变化的不确定性。预期的结果是固体-表面相互作用的现场表征和多相流体流动的预测。该项目通过提高超临界二氧化碳储存项目的注入性、储存效率和安全性，使澳大利亚资源部门受益。

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.
