Storing CO2 as solid hydrate in shallow aquifers: Electrical resistivity measurements in hydrate-bearing sandstone
Gauteplass, Jarand; Almenningen, Stian; Ersland, Geir (Journal article; Peer reviewed, 2020)A recent proposed carbon dioxide (CO2) storage scheme suggests solid CO2 hydrate formation at the base of the hydrate stability zone to facilitate safe, long-term storage of anthropogenic CO2. These high-density hydrate ... -
Transport and storage of CO2 in natural gas hydrate reservoirs
Ersland, Geir; Husebø, Jarle; Graue, Arne; Kvamme, Bjørn (Peer reviewed; Journal article, 2009-02)Storage of CO2 in natural gas hydrate reservoirs may offer stable long term deposition of a greenhouse gas while benefiting from methane production, without requiring heat. By exposing hydrate to a thermodynamically preferred ... -
Transport mechanisms for CO2-CH4 exchange and safe CO2 storage in hydrate-bearing sandstone
Birkedal, Knut Arne; Hauge, Lars Petter; Graue, Arne; Ersland, Geir (Peer reviewed; Journal article, 2015-06-08)CO2 injection in hydrate-bearing sediments induces methane (CH4) production while benefitting from CO2 storage, as demonstrated in both core and field scale studies. CH4 hydrates have been formed repeatedly in partially ... -
Unlocking multimodal PET-MR synergies for geoscience
Brattekås, Bergit; Gauteplass, Jarand; Brekke, Njål; Fernø, Martin; Ersland, Geir (Journal article; Peer reviewed, 2020)The recent combination of positron emission tomography (PET) and magnetic resonance (MR) imaging modalities in one clinical diagnostic tool represents a scientific advancement with high potential impact in geoscientific ...
