The effect of undrained heating on a fluid-saturated hardened cement paste
Siavash Ghabezloo, Jean Sulem, Jérémie Saint-Marc
The effect of undrained heating on volume change and induced pore pressure increase is an important point to properly understand the behaviour and evaluate the integrity of an oil…
Evaluation of a permeability-porosity relationship in a low permeability creeping material using a single transient test
Siavash Ghabezloo, Jean Sulem, Jérémie Saint-Marc
A method is presented for the evaluation of the permeability-porosity relationship in a low-permeability porous material using the results of a single transient test. This method a…
Effective stress law for the permeability of a limestone
Siavash Ghabezloo, Jean Sulem, Sylvine Guédon +1
The effective stress law for the permeability of a limestone is studied experimentally by performing constant head permeability tests in a triaxial cell with different conditions o…
Poromechanical behaviour of hardened cement paste under isotropic loading
Siavash Ghabezloo, Jean Sulem, Sylvine Guédon +2
The poromechanical behaviour of hardened cement paste under isotropic loading is studied on the basis of an experimental testing program of drained, undrained and unjacketed compre…
Stress orientation evaluated from strain localisation analysis in Aigion fault
Jean Sulem
Within the frame of the 'CRL' (Corinth Rift Laboratory project) (Cornet et al, 2004a) centered on the south western sector of the Gulf of Corinth (http://www.corinth-rift-lab.org),…
Finite element analysis of the indentation test on rocks with microstructure
Jean Sulem, Miguel Cerrolaza
Strength parameters of rocks are currently determined from indentation tests. In this paper, a finite element analysis of this test is presented and scale effect is studied. The ro…
Thermo-Poro-Mechanical Properties of Clayey Gouge and Application to Rapid Fault Shearing
Jean Sulem, Paul Lazar, Ioannis Vardoulakis
In this paper, the mechanism of fault pressurization in rapid slip events is analyzed on the basis of a complete characterization of the thermo-poro-mechanical behavior of a clayey…
Stress dependent thermal pressurization of a fluid-saturated rock
Siavash Ghabezloo, Jean Sulem
Temperature increase in saturated porous materials under undrained conditions leads to thermal pressurization of the pore fluid due to the discrepancy between the thermal expansion…
