• CO2 Foam Using non-ionic Surfactants : For Increased Storage Capacity and Oil Recovery 

      Føyen, Tore Lyngås (Doctoral thesis, 2020-12-18)
      Large-scale carbon capture and storage is needed to achieve the target set forward by the Paris agreement; to limit global warming to 1.5 °C. The primary obstacle for implementing large-scale carbon capture and storage is ...
    • CO2 mobility reduction using foam stabilized by CO2- and water-soluble surfactants 

      Føyen, Tore Lyngås; Alcorn, Zachary Paul; Fernø, Martin; Barrabino, Albert; Holt, Torleif (Journal article; Peer reviewed, 2021)
      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 ...
    • Dos and Don’ts When Developing a System to Investigate Spontaneous Imbibition in Unconsolicdated Porous Media 

      Brattekås, Bergit; Føyen, Tore Lyngås; Vabø, Trond; Haugland, Håkon; Reite, Simon I.; Saunes, Anders S.; Fernø, Martin (Peer reviewed; Journal article, 2019)
      This paper describes the development of a consistent model system to measure spontaneous imbibition and determine saturation functions in unconsolidated porous media. Sand grains or glass beads were packed in up to 0.5 m ...
    • Increased CO2 storage capacity using CO2-foam 

      Føyen, Tore Lyngås; Brattekås, Bergit; Fernø, Martin; Barrabino, Albert; Holt, Torleif (Journal article; Peer reviewed, 2020)
      Reduction of the CO2 mobility is beneficial during subsurface sequestration of anthropogenic CO2 in saline aquifers and hydrocarbon reservoirs by mitigating flow instabilities leading to early gas breakthrough and poor ...
    • Onset of Spontaneous Imbibition 

      Føyen, Tore Lyngås (Master thesis, 2017-06-22)
      The spontaneous imbibition process in porous media is an important recovery mechanism and is governed by capillary forces that arise when two immiscible fluids are present in the pore space. This thesis presents new ...
    • 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 (Journal article; Peer reviewed, 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 ...
