  • Applicability of Noble Gases for CO2 Capture and Storage Monitoring 
    Weber, Ulrich Wolfgang (Doctoral thesis / Doktoravhandling, 2021)
    Carbon capture and storage is a climate change mitigation technology that can help limit global warming. Monitoring strategies are put into place to inform on the fate of the injected CO2. Noble gases can play an important ...
  • In situ observation of helium and argon release during fluid-pressure-triggered rock deformation 
    Roques, Clement; Weber, Ulrich Wolfgang; Brixel, Bernard; Krietsch, Hannes; Dutler, Nathan; Brennwald, M.S.; Villiger, Linus; Doetsch, Joseph; Jalali, Mohammadreza; Gischig, Valentin; Amann, Florian; Valley, Benoit; Klepikova, Maria; Kipfer, Rolf (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    Temporal changes in groundwater chemistry can reveal information about the evolution of flow path connectivity during crustal deformation. Here, we report transient helium and argon concentration anomalies monitored during ...
  • In-situ experiment reveals CO2 enriched fluid migration in faulted caprock 
    Weber, Ulrich Wolfgang; Rinaldi, Antonio Pio; Roques, Clément; Wenning, Quinn C.; Bernasconi, Stefano M.; Brennwald, Matthias S.; Jaggi, Madalina; Nussbaum, Christophe; Schefer, Senecio; Mazzotti, Marco; Wiemer, Stefan; Giardini, Domenico; Zappone, Alba; Kipfer, Rolf (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    Abstract The sealing characteristics of the geological formation located above a CO 2 storage reservoir, the so-called caprock, are essential to ensure efficient geological carbon storage. If CO 2 were to leak through the ...
  • Techno-Economic Aspects of Noble Gases as Monitoring Tracers 
    Weber, Ulrich Wolfgang; Kampman, Niko; Sundal, Anja (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    A comprehensive monitoring program is an integral part of the safe operation of geological CO2 storage projects. Noble gases can be used as geochemical tracers to detect a CO2 anomaly and identify its origin, since they ...
