ABSTRACT: The uniaxial and triaxial compression tests have been conducted on 38 mm diameter core plugs to characterize the mechanical properties of the Montney strata. The crack closure, crack initiation, crack damage and peak stresses are determined based on the test results. The axial strain response method (ASRM), the lateral strain response method (LSRM), the volumetric strain method (VSM) and the crack volumetric strain method (CVSM) are used to estimate these 4 stress thresholds. The results show that all methods can give acceptable values. ASRM and LSRM depend heavily on the origin of the stress-strain curve. In addition, the Young’s modulus, Poisson’s ratio, cohesion and friction angle are obtained from the test results.
