We conduct geomechanical property characterization across a wide range of geomaterials, from high-permeability reservoir rocks to ultra-tight mudrocks and caprocks. Our laboratory measures compressibility, elastic and inelastic deformation, strength, permeability, and coupled hydro-mechanical parameters using triaxial, oedometer, core-flooding, and innovative experimental techniques. We measure drained and undrained responses, Biot coefficient, stress-dependent poromechanical properties, and time-dependent response. Based on these measurements, we establish porosity–permeability relationships and constitutive relationships, supporting applications in geoenergy systems.
