• CO2 mobility reduction using foam stabilized by CO2- and water-soluble surfactants 

      Føyen, Tore Lyngås; Alcorn, Zachary Paul; Fernø, Martin; Barrabino, Albert; Holt, Torleif (Peer reviewed; Journal article, 2020)
      Foam can reduce CO2 mobility to improve the sweep efficiency during injection into subsurface geological formations for CO2 storage and enhanced oil recovery. However, CO2 foams are thermodynamically unstable, so they must ...
    • Core-scale sensitivity study of CO2 foam injection strategies for mobility control, enhanced oil recovery, and CO2 storage 

      Alcorn, Zachary Paul; Fredriksen, Sunniva; Sharma, Mohan; Føyen, Tore Lyngås; Wergeland, Connie; Fernø, Martin; Graue, Arne; Ersland, Geir (Journal article; Peer reviewed, 2020)
      This paper presents experimental and numerical sensitivity studies to assist injection strategy design for an ongoing CO2 foam field pilot. The aim is to increase the success of in-situ CO2 foam generation and propagation ...
    • Pore-and core-scale insights of nanoparticle-stabilized foam for CO2-enhanced oil recovery 

      Alcorn, Zachary Paul; Føyen, Tore Lyngås; Gauteplass, Jarand; Benali, Benyamine; Soyke, Aleksandra; Fernø, Martin (Peer reviewed; Journal article, 2020)
      Nanoparticles have gained attention for increasing the stability of surfactant-based foams during CO2 foam-enhanced oil recovery (EOR) and CO2 storage. However, the behavior and displacement mechanisms of hybrid ...
    • Pore-scale bubble population dynamics of CO2-foam at reservoir pressure 

      Benali, Benyamine; Føyen, Tore Lyngås; Alcorn, Zachary Paul; Haugen, Malin; Gauteplass, Jarand; Kovscek, Anthony R.; Fernø, Martin (Peer reviewed; Journal article, 2022)
      The flow of CO2 foam for mobility control in porous media is dictated by the foam texture, or bubble density, which is commonly expressed as the number of bubbles per unit of flowing gas. In most high-pressure laboratory ...
