1st Caprock Integrity & Gas Storage Symposium 2024 – Extended abstracts

The CIGSS aims at providing a platform for the exchange and discussion of scientific, technological, industrial, and regulatory advances related to the integrity of caprocks in the context of geological storage of CO₂ and gas storage in general. The specialised conference is addressed to research institutes, industry, and government agencies. 
The event took place over two days, on 24 and 25 January 2024. The first day was devoted to a symposium with government agencies, industry representatives and invited speakers.

Abstract

In the context of the urgency of climate change and the need to drastically reduce greenhouse gases in the atmosphere, it is essential to capture and store unavoidable CO₂ emissions, alongside other vital emission reduction measures. Indeed, some CCS is essential to achieve the 2050 carbon neutrality targets that industrialised countries have set themselves. The Caprock Integrity & Gas Storage Symposium (CIGSS) aims at providing and establishing a platform for the exchange and discussion of scientific, technological, industrial, and regulatory advances related to the integrity of caprocks in the context of geological storage of CO₂ and gas storage in general. 

Purposely organised in Saint-Ursanne, with the support of the Mont Terri underground rock laboratory and its partners, the CIGSS benefits from the invaluable contribution and knowledge of the radioactive waste disposal commu-nity. Their experience is indispensable, particularly when it comes to gas migration in low-permea-bility rocks such as claystone, which is a promising host rock for nuclear waste disposal and caprock for CO₂ storage. The first day of this 1^st CIGSS is devoted to a symposium with academic community, government agencies, industry representatives and invited speakers. The following themes are on the agenda: public acceptance, regulation, site screening and exploration, characterization and behavior of geo-logical reservoirs and caprocks, key research developments of geological storage of CO₂ and other gases like H₂, and expectation of CO₂ producers. The second day is devoted to scientific exchange and discussion during poster sessions, in the field of fault, caprock and borehole integrity, and gas storage in general. In summary, the 2-day symposium is arranged around five core themes:

• Small-scale laboratory experiments
• Medium-scale rock laboratory experiments toward pilot-scale projects
• Local and regional geological and structural investigations of potential sites
• Numerical studies
• Innovative monitoring systems

The core themes will allow practitioners and researchers from diverse backgrounds to progress beyond current knowledge barriers, and lay out a framework for the evaluation of caprock integrity in claystone and possibly increasing the public acceptance of geological gas storage.
