Oral Presentation: Passive Seismic Monitoring with Surface Distributed Acoustic Sensing

Abstract opening:
Carbon capture and sequestration sites are chosen with great care to ensure favourable conditions for the safe long-term storage of CO₂. A robust measurement, monitoring, and verification (MMV) framework remains central to ensuring the long-term security of geological CO₂ storage. A reliable MMV plan must be able to monitor any potential CO₂ leakage—no matter how unlikely—in a cost-efficient manner. This study explores the use of ambient seismic noise recorded with surface-distributed acoustic sensing (DAS) for imaging subsurface changes caused by potential CO₂ leakage in the overburden…
