  • Nilsen, Halvor Møll; Herrera, Paulo; Ashraf, Seyed Meisam; Ligaard, Ingeborg S.; Iding, Martin; Hermanrud, Christian; Lie, Knut-Andreas; Nordbotten, Jan Martin; Dahle, Helge K.; Keilegavlen, Eirik (Journal article, Elsevier, 2011)
    When injected in deep saline aquifers, CO2 moves radially away from the injection well and progressively higher in the formation because of buoyancy forces. Analyzes have shown that after the injection period, CO2 will ...
  • Karlsen, Kenneth Hvistendahl; Lie, Knut-Andreas; Natvig, Jostein Roald; Nordhaug, Hans Fredrik; Dahle, Helge K. (Journal article; Peer reviewed, Elsevier, 2001)
    Many numerical methods for systems of convection-diffusion equations are based upon an operator splitting formulation, where convective and diffusive forces are accounted for in separate substeps. We describe the nonlinear ...
  • Nordhaug, Hans Fredrik; Celia, Michael A.; Dahle, Helge K. (Journal article; Peer reviewed, Elsevier Science, 2003)
    Two-phase flow in porous media is characterized by fluid-fluid interfaces that separate the fluid phases at the pore scale. These interfaces support pressure differences between phases, and their dynamics allow for ...
  • Berre, Inga; Dahle, Helge K.; Karlsen, Kenneth Hvistendahl; Nordhaug, Hans Fredrik (Preprint, American Mathematical Society, 2002)
  • 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 (Journal article, Elsevier, 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 ...
  • Nordhaug, Hans Fredrik; Dahle, Helge K.; Espedal, Magne S.; Gray, William G.; Celia, Michael A. (Journal article, The XIII international conference on computational methods in water resources, 2000)
    Based on the procedure of (Gray & Hassanizadeh 1998) we state macroscale conservation equations for multi phase flow in porous media including interfacial area as a variable. The phases we consider are a solid phase, a ...
  • Gasda, Sarah Eileen; Stephansen, Annette; Aavatsmark, Ivar; Dahle, Helge K. (Journal article, Elsevier, 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. ...
