    • 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 ...

    • Dynamic estimates of extreme-case CO2 storage capacity for basin-scale heterogeneous systems under geological uncertainty 

      Pettersson, Per; Tveit, Svenn; Gasda, Sarah Eileen (Peer reviewed; Journal article, 2022)
      Geological CO2 storage is expected to grow dramatically in the coming decades to meet global climate targets. Assessment of worldwide storage resources using static methods indicates significant theoretical potential for ...

    • Effective permeability of deformation bands in fault damage zones – Can deformation bands reduce the risk of fault leakage? 

      Berge, Runar Lie; Gasda, Sarah Eileen; Keilegavlen, Eirik; Sandve, Tor Harald (Chapter; Peer reviewed; Conference object, 2021)
      Faults are major geological structures that can dominate the flow paths in subsurface reservoirs by, e.g., connecting otherwise unconnected layers. In CO2 storage sites where the faults act as the main structural trap, the ...

    • Field-scale impacts of long-term wettability alteration in geological CO2 storage 

      Kassa, Abay; Gasda, Sarah Eileen; Landa-Marbán, David; Sandve, Tor Harald; Kumar, Kundan (Peer reviewed; Journal article, 2022)
      Constitutive functions that govern macroscale capillary pressure and relative permeability are central in constraining both storage efficiency and sealing properties of storage systems. Constitutive functions for porous ...

    • A Finite-Volume-Based Module for Unsaturated Poroelasticity 

      Varela, Jhabriel; Gasda, Sarah Eileen; Keilegavlen, Eirik; Nordbotten, Jan Martin (Chapter, 2021)
      In this chapter, we present fv-unsat, a multipoint finite-volume–based solver for unsaturated flow in deformable and nondeformable porous media. The latter is described using the mixed form of Richards’ equation, whereas ...

    • Numerical studies of long-term wettability alteration effects in CO2 storage applications 

      Landa-Marbán, David; Kumar, Kundan; Gasda, Sarah Eileen; Sandve, Tor Harald; Kassa, Abay (Lecture, 2021)
      The wettability of the rock surface in porous media has an effect on the constitutive saturation functions that govern capillary pressure and relative permeability. The term wettability alteration refers to the change of ...
