Abstract:
In order to improve the South West Hub Carbon Capture and Storage (SW Hub) site characterisation and reduce uncertainties around CO2 capacity, injectivity and containment, conceptual fault hydrodynamic models are defined and numerical simulations are carried out to investigate the impact of faults on CO2 plume distribution. These simulations model a worst-case scenario with a plume reaching the interface between the top of the proposed injection unit and a secondary containment unit. The conceptual fault hydrodynamic models are defined to incorporate host rock and fault properties accounting for fault zone lithology, cementation, and cataclastic processes.
