• A pore-scale model for permeable biofilm: Numerical simulations and laboratory experiments 

      Landa-Marban, David; Liu, Na; Pop, Iuliu Sorin; Kumar, Kundan; Pettersson, Per; Bødtker, Gunhild; Skauge, Tormod; Radu, Florin Adrian (Peer reviewed; Journal article, 2018)
      In this paper, we derive a pore-scale model for permeable biofilm formation in a two-dimensional pore. The pore is divided into two phases: water and biofilm. The biofilm is assumed to consist of four components: water, ...
    • An Upscaled Model for Permeable Biofilm in a Thin Channel and Tube 

      Marban, David Landa; Bødtker, Gunhild; Kumar, Kundan; Pop, Iuliu Sorin; Radu, Adrian Florin (Peer reviewed; Journal article, 2020)
      In this paper, we derive upscaled equations for modeling biofilm growth in porous media. The resulting macroscale mathematical models consider permeable multi-species biofilm including water flow, transport, detachment and ...
    • CO2 Convection in Hydrocarbon Under Flowing Conditions 

      Mykkeltvedt, Trine Solberg; Gasda, Sarah Eileen; Sandve, Tor Harald (Peer reviewed; Journal article, 2021)
      Carbon-neutral oil production is one way to improve the sustainability of petroleum resources. The emissions from produced hydrocarbons can be offset by injecting capture CO2 from a nearby point source into a saline aquifer ...
    • Convective Mixing Driven by Non-monotonic Density 

      Elenius, Maria; Gasda, Sarah Eileen (Peer reviewed; Journal article, 2021)
      CO2 injection for enhanced oil recovery (CO2-EOR) or for storage in depleted oil and gas reservoirs can be a means for disposing of anthropogenic CO2 emissions to mitigate climate change. Fluid flow and mixing of CO2 and ...
    • IORSim: A Mathematical Workflow for Field‑Scale Geochemistry Simulations in Porous Media 

      Feldmann, Felix; Nødland, Oddbjørn Mathias; Sagen, Jan; Antonsen, Børre; Sira, Terje; Vinningland, Jan Ludvig; Moe, Robert; Hiorth, Aksel (Peer reviewed; Journal article, 2024)
      Reservoir modeling consists of two key components: the reproduction of the historical performance and the prediction of the future reservoir performance. Industry-standard reservoir simulators must run fast on enormous and ...
    • Numerical Simulations of Viscous Fingering in Fractured Porous Media 

      Berge, Runar Lie; Berre, Inga; Keilegavlen, Eirik; Nordbotten, Jan Martin (Peer reviewed; Journal article, 2024)
      The effect of heterogeneity induced by highly permeable fracture networks on viscous miscible fingering in porous media is examined using high-resolution numerical simulations. We consider the planar injection of a less ...
