    • Assessment of CO2 storage capacity based on sparse data: Skade Formation 

      Elenius, Maria; Skurtveit, Elin; Yarushina, Viktoriya M.; Baig, Irfan; Sundal, Anja; Wangen, Magnus; Landschulze, Karin; Kaufmann, Roland; Choi, Jung Chan; Hellevang, Helge; Podladchikov, Yuri; Aavatsmark, Ivar; Gasda, Sarah (Peer reviewed; Journal article, 2018-12)
      Large North Sea aquifers of high quality are the likely major target for 12 Gt of European CO2 emissions that should be stored in the subsurface by 2050. This involves an upscaling of the present combined injection rate ...

    • Insights into past tectonism from authigenic quartz 

      Hellevang, Helge; Line, Lina Hedvig; Eide, Christian Haug; Jahren, Jens Sigurd; Haile, Beyene Girma (Journal article; Peer reviewed, 2021)
      Authigenic quartz grains carry information that is diagnostic for the thermal history and thereby the burial depth and uplift of sediments. Recycled quartz grains with embayed or rounded authigenic remnants have been ...

    • Interactions between CO2, saline water and minerals during geological storage of CO2 

      Hellevang, Helge (Doctoral thesis, 2006-06-30)

    • Quartz overgrowth textures and fluid inclusion thermometry evidence for basin-scale sedimentary recycling: An example from the Mesozoic Barents Sea Basin 

      Haile, Beyene Girma; Line, Lina Hedvig; Klausen, Tore Grane; Olaussen, Snorre; Eide, Christian Haug; Jahren, Jens; Hellevang, Helge (Journal article; Peer reviewed, 2020)
      Sedimentary recycling has the potential to obscure source-to-sink relationships, provenance interpretations, burial history reconstructions and robust reservoir quality predictions in siliciclastic sedimentary basins. Here, ...

    • SUCCESS: SUbsurface CO2 storage–Critical elements and superior strategy 

      Aker, Eyvind; Bjørnarå, Tore Ingvald; Braathen, Alvar; Brandvoll, Øyvind; Dahle, Helge K.; Nordbotten, Jan Martin; Aagaard, Per; Hellevang, Helge; Alemu, Binyam Lema; Pham, Van Thi Hai; Johansen, Harald; Wangen, Magnus; Nøttvedt, Arvid; Aavatsmark, Ivar; Johannessen, Truls; Durand, Dominique (Peer reviewed; Journal article, 2011)
      SUCCESS is a Center for Environmental Energy Research in Norway and performs research related to geological storage of CO2 in the subsurface. The SUCCESS centre is established by the Research Council of Norway together ...
