In this course we will review the geological features of possible storage sites, focussing on the heterogeneity and presence of faults. This will enable an assessment of the impact of complex heterogeneous geology on the storage efficiency and security of the system in terms of the possible migration along faults that transect a reservoir, or through leaky seal layers.
In modelling CO2, we will firstly consider the simulation objectives, the impact of aquifer properties, top and bottom seal diffusion, areal coverage of the pressure front, and secondary reservoirs for expansion. Various model approaches will be considered, namely, material balance, sector, full field, two-phase vs compositional, areal and stratigraphic coverage. The simulation of various development strategies will be tackled along with the long-term modelling of CO2 interactions and plume behaviour. The alternative approaches to the estimation of storage capacity will also be investigated.
This course is aimed at subsurface oil and gas professionals who are familiar with the basics of CCS.
