In recent years, there has been an increasing interest in production of methane gas from hydrate-bearing sediments, located below the permafrost in arctic regions and offshore within the continental margins. In order to simulate the
geomechanical response of the hydrate accumulation during gas production, comprehensive evaluation of the sediments’ properties is imperative. This paper presents an analysis of the mechanical properties of methane-hydratebearing sediments determined through numerical simulation of drained triaxial compression tests, which lead to a best-fit match to laboratory test results. Unlike previous analyses, the adjustment of the numerical to the experimental results was performed for the entire stress-strain curves, and therefore, enables a better understanding of the material constitutive relations. The mechanical properties are found to be mostly governed by hydrate saturation, effective confining pressure, and mobilized strength and dilation properties.
