    • 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 ...

    • 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 ...

    • Pore-level Ostwald ripening of CO2 foams at reservoir pressure 

      Benali, Benyamine; Sæle, Aleksandra Magdalena; Liu, Na; Fernø, Martin; Alcorn, Zachary Paul (Journal article; Peer reviewed, 2023)
      The success of foam to reduce CO2 mobility in CO2 enhanced oil recovery and CO2 storage operations depends on foam stability in the reservoir. Foams are thermodynamically unstable, and factors such as surfactant adsorption, ...

    • 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 (Journal article; Peer reviewed, 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 ...

    • Pressure Measurements for Monitoring CO2 Foam Pilots 

      Karakas, Metin; Alcorn, Zachary Paul; Aminzadeh, Fred; Graue, Arne (Journal article; Peer reviewed, 2022)
      This study focuses on the use of pressure measurements to monitor the effectiveness of foam as a CO2 mobility control agent in oil-producing reservoirs. When it is applied optimally, foam has excellent potential to improve ...

    • Unsteady-State CO2 Foam Generation and Propagation: Laboratory and Field Insights 

      Alcorn, Zachary Paul; Sæle, Aleksandra Magdalena; Karakas, Metin; Graue, Arne (Journal article; Peer reviewed, 2022-09-07)
      This work presents a multiscale experimental and numerical investigation of CO2 foam generation, strength, and propagation during alternating injection of surfactant solution and CO2 at reservoir conditions. Evaluations ...

    • Unsteady-state CO2 foam injection for increasing enhanced oil recovery and carbon storage potential 

      Sæle, Aleksandra Magdalena; Graue, Arne; Alcorn, Zachary Paul (Journal article; Peer reviewed, 2022)
      The efficiency of CO2 injection for enhanced oil recovery (EOR) and carbon storage is limited by severe viscosity and density differences between CO2 and reservoir fluids and reservoir heterogeneity. In-situ generation of ...
