Project: Effective monitoring of long-term site stability for transparent carbon capture and storage hazard assessment

Acronym	ENSURE
Project Topic	Microseismic monitoring represents a key surveillance technology to verify the integrity of any large-scale CO2 storage, since the interpretation of microseismic events provides direct insights on of CO2 migration within the storage reservoir and on potential caprock failure within the overburden. Verification of seal integrity is a major challenge of CCS technology as it requires the recognition of tiny precursor movements as indicators of injection-related reservoir and caprock dynamics before potential seal failure. Optimally designing, cost-efficient, fit-forpurpose monitoring systems for this purpose have been identified as a critical knowledge gap. At the same time, public acceptance of CCS technology hinges on the ability of the general public to differentiate between harmless microseismic deformations (perceived risks) and earthquakes with damaging potential (actual risks). To avoid the pitfall that improved microseismic monitoring, and thus enhanced operational safety, is perceived as an increased threat due to a larger number of registered, though small events, we see the need for a more effective communication strategy to establish trust and transparency between CO2 storage operators and the public.
