摘要: Abstract In this study, macro- and micro-geomechanical properties of shales were investigated at millimeter- micrometer-scale using an example the Woodford Shale. Geomechanical properties, such as uniaxial (unconfined) compressive strength Young's modulus, quantified millimeter-scale compared with results from micro-compression testing experiments FIB-SEM-nanofabricated micro-pillars. Size-scale compositional/structural heterogeneity effect on elasto-plastic deformation failure behavior investigated. Also, relationship between elemental/mineral composition unconfined a micrometer-scale, was discussed. It shown that geomechanical are scale-dependent strongly affected by anisotropy. particular, showed non-uniformly distributed modulus within Shale rock samples. demonstrated, shales, tend to be different minerals and/or pores, while same millimeter-scale, governed micro-facies (and/or micro-fractures) present rock. This shows can dramatically depending scale investigation these rocks, therefore not easily transferable across scales.
