Dr. Sam Krevor, Senior Lecturer in the Department of Earth Science & Engineering at Imperial College London, will be presenting on "The Multi Scale Fluid Physics of Subsurface CO2 Storage".

Abstract: 

A number of assessments suggest that the widespread storage of CO2 in deep subsurface sedimentary rocks will be needed to avoid dangerous climate change. It is estimated that storage rates will need to be in the order of 1-10 GtCO2 per year by 2050, with cumulative storage of over 1000 GtCO2 by the end of the century. The management of individual storage sites is increasingly understood with a number of projects injecting at rates around a million tCO2 per year. However, challenges remain for the scale-up of injection rates from megatonnes to gigatonnes per year. Central to these challenges are the limitations to modelling and predicting injected CO2 movement and immobilization in the subsurface. I will present research in 3 areas of subsurface fluid flow ranging across scales: an exploration of the pore scale fluid dynamics underlying the use of Darcy’s law to model two-phase flow, the upscaled impacts of small scale heterogeneity on CO2 migration and trapping, and an analysis of the implications of climate change mitigation targets to growth rates and global resource capacity of subsurface CO2 storage.
