• Novel true triaxial apparatus applied to the study of sand mass production under anisotropic stress conditions. 

      Walle, Lars Erik; Berntsen, Andreas Nicolas; Papamichos, Euripides (Rock Mechanics for Natural Resources and Infrastructure Development (ISRM);2019, Chapter; Peer reviewed, 2019)
      Using a novel true triaxial setup, sand production tests on hollow quasi-cylinder Castlegate sandstone specimens have been performed on irreducible water saturated specimens with oil flow under varying levels of axial and ...
    • Salt clogging during supercritical CO2 injection into a downscaled borehole model 

      Berntsen, Andreas Nicolas; Todorovic, Jelena; Raphaug, Martin Hagen; Torsæter, Malin; Chavez Panduro, Elvia Anabela; Gawel, Kamila (Journal article; Peer reviewed, 2019)
      Injection of CO2 into saline storage aquifers is often accompanied by drying of the formation water and salt precipitation. Subsequent salt clogging of a well bore and the near wellbore rock matrix may lead to injectivity ...
