Today, PhD student Emily Flicos delivered our weekly seminar, with a presentation titled ‘CCS & permeability: thinking about uncertainty through a perturbation analysis’.
Carbon Capture and Storage (CCS) has a crucial role to play in the journey to Net Zero and represents an enormous challenge due to the scale of storage that we must meet.
One vital part of realising this challenge involves developing greater understanding of the physics of plume dynamics beneath the surface at carbon storage sites, which is where Emily’s work comes in. Emily explained how, due to the limited resolution of observation methods, there is high uncertainty in measurements of subsurface geological properties. This is significant because these properties can be highly heterogenous, and this heterogeneity effects plume migration.
Emily talked us through her approach to modelling subsurface flows using a perturbation analysis, giving fascinating insight into the maths behind improving understanding of permeability variation.
Thank you Emily for such an informative seminar!
