Publication Overview
The 45 presentations and 17 posters covered a range of topics, with sessions on cost-effective monitoring of large projects, permit requirements, induced seismicity, shallow monitoring, geophysical monitoring and CO₂ relationships, pressure monitoring applications, monitoring tools for shallow, surface and deep monitoring, update on projects, and post-closure monitoring. As well as the new results and developments, new at this meeting was a group-work exercise created by Sue Hovorka of the University of Texas. This involved the groups designing monitoring plans for fictional but realistic storage sites, and then these being actually tested with leakage scenarios.
Publication Summary
The overall conclusions of the meeting included identifying the value of pressure based monitoring for assessing reservoir behaviour and in the overburden for leak detection, the potential in fibre-optic distributed acoustic sensing (DAS) and permanent sources, the benefits of good engagement with regulators, the importance of geomechanical analysis using the monitoring data, and the feasibility of offshore monitoring for leak detection and quantification. Overall, a meeting packed with new developments in all aspects of monitoring CO₂ storage, shared and discussed by this group of leading international experts. Monitoring continues to make great advances.
