An important difference between monitoring for hydrocarbon production and gas storage operations is the concern of leakage and its detection. The primary leakage pathways are legacy wells and damage zones around faults whose locations and existence are not necessarily known a priori. Further these leakage pathways are not static risks but can be activated during operations. When leakage occurs the quantities are (hopefully) small and detection is at or below of monitoring techniques. Uncertainties can be reduced or at least quantified with the help simulation and with their help optimal monitoring strategies can be devised. The larger the uncertainty the more simulations are required. Hence there is a need for efficient models representing the dominant features and processes. In this presentation I will cover three approaches: Multi-physics coupled flow diagnostics, multi-scale multi-physics modelling of leakage processes in the damage zone of faults and leakage modelling in vertically integrated modelling for CO2 storage.
