Abstract
The development of geological carbon storage is critically dependent on consistent and reliable storage capacities. Evaluating storage capacities in highly faulted basins are specifically challenging due to the uncertainties in fault and compartment properties. The relation between fault and compartment properties and effective CO2 storage capacity was investigated using numerical simulations. This can enable quick, easy and accurate local estimates to identify feasible storage sites. The large sensitivity of storage capacity to the type of enclosure and fault permeability indicates that pressure build-up at the fault is often the deciding factor for CO2 storage capacity. It accentuates the importance of understanding the faults of the compartment. During an estimate, the specific properties of a compartment give a range of possible storage capacities. This subsequently indicates the uncertainties in the storage capacity of the compartment and similar compartments in the local region.
