This system enables high-resolution consolidation and poromechanical testing of clay-rich geomaterials under controlled vertical stress conditions. It is specifically designed to generate full-saturation, resedimented specimens with well-defined stress and porosity states.
Key Capabilities:
Maximum Vertical Stress: Up to 100 MPa
Oedometer configuration (zero lateral strain)
Sample Preparation: Fully saturated, resedimented specimens with tunable void ratio
Stress-Porosity Control: Enables systematic correlation of porosity with vertical stress
Advanced Testing Features:
In-situ multiphase fluid injection under controlled loading
CO₂ and brine flow tests for breakthrough experiments
Capillary pressure and relative permeability characterization
Measured Properties:
Porosity
Consolidation parameters (e.g., Cc, Cr, Cv,Ca)
Intrinsic permeability (k), Relative permeability (kr)
CO₂ breakthrough pressure
