Seismic modelling of metre-scale normal faults at a reservoir-cap rock interface in Central Spitsbergen, Svalbard: implications for CO2 storage
On Svalbard (Arctic Norway), a pilot-scale research project has been established to investigate the feasibility of storing locally produced CO2 in geological aquifers onshore. Drilling, geophysical and geological data acquisition and water-injection tests confirm the injectivity and storage capacity...

On Svalbard (Arctic Norway), a pilot-scale research project has been established to investigate the feasibility of storing locally produced CO2 in geological aquifers onshore.

Excellent outcrops of the reservoir-caprock units 15 km from the planned injection site allow for detailed sedimentological and structural studies, and complement 2D seismic data acquired onshore and offshore. In this contribution, we focus on small-scale (metre-scale displacement) normal faults present in both reservoir and caprock to quantify their seismic detectability.
