• Analytical models for onset of sand production under isotropic and anisotropic stresses in laboratory tests 

      Papamichos, Euripides (Journal article; Peer reviewed, 2019)
      Four failure criteria, a simplified Mohr–Coulomb, a Mohr–Coulomb, a von Mises and a Drucker–Prager model are considered for borehole failure and sand onset predictions. The von Mises is a special case of the Drucker–Prager. ...
    • Analytical Solutions of Carbonate Acidizing in Radial Flow 

      Strongylis, Polyneikis; Papamichos, Euripides (Peer reviewed; Journal article, 2021)
      The flow of reactive fluids into porous media, a phenomenon known as reactive infiltration, is important in natural and engineered systems. While most of the studies in this area cover theoretical and experimental analyses ...
    • 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 ...
    • Reactive instabilities in linear acidizing on carbonates 

      Papamichos, Euripides; Strongylis, Polyneikis; Bauer, Andreas (Peer reviewed; Journal article, 2020)
      Acid injection, reactive instabilities and wormholing in carbonate reservoirs is investigated through the analysis of the linear acidizing problem theoretically and experimentally. Theoretically acidizing was analyzed by ...
