Catrin is a 2nd year PhD student in the subsurface CO2 research group, part of the Earth Science and Engineering department at Imperial College London. Her research is supported by BP and the Imperial ‘Transition Towards a Zero Pollution Society’ DTP. Catrin’s project uses the latest in petrophysical and digital rock core technology to improve our understanding of the impact of heterogeneity on capillary trapping of CO2 in the subsurface. Her research encompasses mathematical analysis, numerical flow simulation and laboratory X-ray CT core flood experiments. Catrin is developing workflows to create physics-based representations of capillary heterogeneity trapping in field scale simulations, with the aim to improve the reliability of models used to assess potential geological CO2 storage sites.
