This project aims to investigate the reactive behaviour of carbon dioxide in sandstone rocks to improve the safety of carbon sequestration operations. The project will develop new techniques to link fluid flow behaviour and geochemistry analysis, using high resolution 3D microscopy within geologic samples. The results will demonstrate the level of stability and security of carbon dioxide in underground sandstone rocks, and lead to safer design of sequestration operations.

该项目旨在研究二氧化碳在砂岩岩石中的反应行为，以提高碳封存作业的安全性。该项目将开发新技术，利用地质样品中的高分辨率三维显微镜，将流体流动行为和地球化学分析联系起来。研究结果将证明地下砂岩中二氧化碳的稳定性和安全性，并导致更安全的封存操作设计。
