Summary
I am a mechanical engineer, turned Earth scientist, with a passion for fluid mechanics. My research is focused on understanding multiphase flow in the subsurface across scales – from μm to km, with application to carbon sequestration, petroleum engineering and groundwater hydrology.
In a changing energy landscape, where significant focus is shifting towards reducing carbon emissions and more efficient utilisation of existing hydrocarbon reservoirs, my research tackles fundamental issues concerning the sustainable use of energy resources, namely: How can captured CO2 be effectively stored in subsurface reservoirs? How can existing oil/gas reservoirs be utilised for efficient production after primary drainage? How can geothermal systems be exploited for effective energy production?
I use a combination of theory, high-precision numerical methods and carefully designed laboratory experiments to understand the multiphase flow of fluids through the subsurface at changing spatial and temporal scales:
Pore scale: Understanding fundamental fluid-fluid interactions across unstable interfaces, in particular viscous instabilities and capillary pressure.
Core scale: Characterising multiphase flow through heterogeneous, subsurface rock cores using a combination of X-ray CT scanning and high-fidelity 3D numerical simulations.
Field scale: Utilising large scale simulations incorporating upscaled heterogeneous functions to understand fluid migration and trapping in subsurface reservoirs.
Through this combined multi-scale approach, informed models and predictions can be made regarding the sustainable use of energy resources at large scale. I have expertise in analysing large datasets with HPC simulations, creating novel numerical methods and the application of state-of-the-art core flooding experiments with X-ray CT scanning.
I am currently part of the Subsurface CO2 group in the Department of Earth Science & Engineering at Imperial College London. For news and updates please visit the website:
