• International Conference on Greenhouse Gas Technologies (GHGT-12) Models for CO2 injection with coupled thermal proce 

      Kometa, Bawfeh Kingsley; Gasda, Sarah Eileen; Aavatsmark, Ivar (Peer reviewed; Journal article, 2014)
      Large-scale models of carbon dioxide (CO2) storage in geological formations must capture the relevant physical, chemical and thermodynamic processes that affect the migration and ultimate fate of injected CO2. These processes ...
    • Models for CO2 injection with coupled thermal processes 

      Kometa, Bawfeh Kingsley; Gasda, Sarah Eileen; Aavatsmark, Ivar (Peer reviewed; Journal article, 2014)
      Large-scale models of carbon dioxide (CO2) storage in geological formations must capture the relevant physical, chemical and thermodynamic processes that affect the migration and ultimate fate of injected CO2. These processes ...
    • Multiscale mass conservative domain decomposition preconditioners for elliptic problems on irregular grids 

      Sandvin, Andreas; Nordbotten, Jan Martin; Aavatsmark, Ivar (Peer reviewed; Journal article, 2011-06)
      Multiscale methods can in many cases be viewed as special types of domain decomposition preconditioners. The localisation approximations introduced within the multiscale framework are dependent upon both the heterogeneity ...
    • 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 ...
    • A unified multilevel framework of upscaling and domain decomposition 

      Sandvin, Andreas; Nordbotten, Jan Martin; Aavatsmark, Ivar (Conference object, 2010)
      We consider multiscale preconditioners for a class of mass-conservative domain-decomposition (MCDD) methods. For the application of reservoir simulation, we need to solve large linear systems, arising from finite-volume ...
    • Upscaled modeling of CO2 injection and migration with coupled thermal processes 

      Gasda, Sarah Eileen; Stephansen, Annette; Aavatsmark, Ivar; Dahle, Helge K. (Peer reviewed; Journal article, 2013)
      A practical modeling approach for CO2 storage over relatively large length and time scales is the vertical-equilibrium model, which solves partially integrated conservation equations for flow in two lateral dimensions. We ...
