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 ...
