Seismic Reservoir Simulation & 4D Time-Lapse Monitoring for Subsurface Geological Hydrogen Storage Management
Project abstract
Subsurface sedimentary geology acts as both a conduit and containment system, enabling fluid flow and providing vast storage capacity for hydrogen. Geological hydrogen storage in sandstone reservoirs is critical for seasonal energy balance and resilient energy systems. This research develops an integrated workflow combining petroelastic modelling, reservoir simulation, and 4D seismic forward modelling applied to a North Sea analogue field. Quantitative monitoring (QM) addresses key challenges—pressure saturation ambiguity, shifting fluid contacts, fluid displacement, and H₂ distribution near the wellbore—by analysing dynamic simulation outputs and petroelastic properties. Expected outcomes include pressure dependent seismic changes predicted from elastic moduli (M), velocities (Vp, Vs), impedances (Ip, Is), and fluid saturation for QM. The integrated approach provides crucial areal reservoir property inputs for simulation and history matching, enabling optimisation of 3-D reservoir models and prediction of infill wells for supporting storage efficiency toward future field wide hydrogen production cycles in potential geological hydrogen storage sites.
