I am a PhD candidate and member of Matthai’s research team. My research is part of the GeoCQuest project, involving a close collaboration between the three leading universities: Stanford, Cambridge and Melbourne. The first phase of this project was focused on the quantification of the impact of geoheterogeneity on CO2 plume migration in storage sites. This work is aimed at a better understanding of multi-phase flow. My contribution lies in developing tensorial, rate-dependent saturation functions for reservoir simulation that take into account the influence of nested geoheterogeneity at multiple scales, and different force balance ratios.

  1. Upscaling workflow (static and dynamic) applied to CRC3-CRC2 cross section.
  2. Stage 1 simulation-based upscaling: determination of directional and flow rate dependent relative permeability curves by core-flooding and numeric experiments.
  3. Stage 2 upscaling: analysis of relative permeability in coarse-scale rectangular subregions of the CRC3-CRC2 cross sectional model. The size of hypothetic field-scale simulation grid blocks is shown by solid lines superposed on the CO2 saturation pattern representing the simulated plume.
