    • DarSIA: An Open-Source Python Toolbox for Two-Scale Image Processing of Dynamics in Porous Media 

      Nordbotten, Jan Martin; Benali, Benyamine; Both, Jakub Wiktor; Brattekås, Bergit; Storvik, Erlend; Fernø, Martin (Journal article; Peer reviewed, 2023)
      Understanding porous media flow is inherently a multi-scale challenge, where at the core lies the aggregation of pore-level processes to a continuum, or Darcy-scale, description. This challenge is directly mirrored in image ...

    • Engineering Meter-scale Porous Media Flow Experiments for Quantitative Studies of Geological Carbon Sequestration 

      Eikehaug, Kristoffer; Haugen, Malin Quande; Folkvord, Olav Parelius; Benali, Benyamine; Bang Larsen, Emil; Tinkova, Alina Valerieva; Rotevatn, Atle; Nordbotten, Jan Martin; Fernø, Martin (Journal article; Peer reviewed, 2024)
      This technical note describes the FluidFlower concept, a new laboratory infrastructure for geological carbon storage research. The highly controlled and adjustable system produces a strikingly visual physical ground truth ...

    • Physical Variability in Meter-Scale Laboratory CO2 Injections in Faulted Geometries 

      Haugen, Malin; Saló-Salgado, Lluís; Eikehaug, Kristoffer; Benali, Benyamine; Both, Jakub Wiktor; Storvik, Erlend; Folkvord, Olav Parelius; Juanes, Ruben; Nordbotten, Jan Martin; Fernø, Martin (Journal article; Peer reviewed, 2024)
      Carbon, capture, and storage (CCS) is an important bridging technology to combat climate change in the transition toward net-zero. The FluidFlower concept has been developed to visualize and study CO2 flow and storage ...

    • 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 Dense Phase CO2 Foam Dynamics during CO2 EOR and CO2 Storage 

      Benali, Benyamine (Doctoral thesis, 2024-09-26)
      Rask befolkningsvekst, økende velstand og økonomisk ekspansjon bidro til at behovet for energi økte med 1.3% i 2022. Det økende energibehovet kan sees på som en trussel ettersom energiproduksjon representerer tre fjerdedeler ...

    • 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, ...

    • A Pore-Level Study of Dense-Phase CO2 Foam Stability in the Presence of Oil 

      Benali, Benyamine; Fernø, Martin; Halsøy, Hilde; Alcorn, Zachary Paul (Journal article; Peer reviewed, 2024)
      The ability of foam to reduce CO2 mobility in CO2 sequestration and CO2 enhanced oil recovery processes relies on maintaining foam stability in the reservoir. Foams can destabilize in the presence of oil due to mechanisms ...

    • 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 ...

    • Pore-scale kinetics of calcium dissolution and secondary precipitation during geological carbon storage 

      Liu, Na; Haugen, Malin; Benali, Benyamine; Landa-Marbán, David; Fernø, Martin (Journal article; Peer reviewed, 2023)
      Geological carbon storage (GCS) in deep underground formations presents a significant opportunity to mitigate anthropogenic emissions of carbon dioxide in the context of climate change. The injected carbon dioxide may ...

    • Pore-scale spatiotemporal dynamics of microbial-induced calcium carbonate growth and distribution in porous media
