IEA Greenhouse Gas R&D Programme

23rd August, 2019, University of Calgary


Success of CO2 Capture and Storage (CCS) technology depends on the safe, secure and long-term storage of CO2 at large-scale (mega tonnes per site).  Upward migration and leakage of injected CO2 along faults is a key risk.  The aim of the workshop is to gain understanding on how faults could influence long-term storage of CO2.  The workshop will build from oil and gas industry experiences, as well as the research community, to gain a clear perspective on fault properties that are important to CO2 storage.  The 1-day will event will provide an opportunity to review laboratory experiments, field studies and modelling results to gain insights on the importance of faults for CO2 storage.  Current practices to evaluate fault seal as well as critical technical gaps will be discussed.


The workshop will provide an opportunity to review current research on CO2 controlled release experiments and what can be learnt from them plus the contribution from simulations.  The 1-day event will document critical issues for CO2 storage related to faults, the experience of current experimental work and identify remaining gaps in knowledge.
