Session 26. Oral Presentation for: Investigation of CO2 flow and trapping in the Otway Basin through digital core analysis and pore-network modelling

Presented on 21 May 2026: Session 26 Safe and efficient geological storage of carbon dioxide (CO2) depends on how CO2 and brine move through reservoir rocks and how much CO2 becomes permanently trapped. In this study, a digital core analysis (DCA) approach is used to investigate CO2-brine flow behaviour and residual trapping in sandstone samples from the Paaratte Formation in the Otway Basin, Australia. High-resolution micro-computed tomography (micro-CT) images were acquired for sandstone core
