“…The transitions of failure mode on the rock cutting with considering the rock heterogeneities with respect to the microcracks, intergrain cracks, temperature variations, and confining pressure were investigated via numerical methods [21][22][23]. Furthermore, the well integrity of inclusion-matrix systems with concerning the effects of pressurized cracks which are randomly distributed around a rigid inclusion or inclusion-matrix interface was theoretically solved via the theory of eigenstrains [24]. The suggested solution can be applied to a hollow cylindrical casing-cement sheath-formation rock system for corrosionrelated problems.…”

Anisotropic and heterogeneous solids, comprising a minimum of two or more elements with different properties, appear pervasively in rock materials including the pore structure and mineral composition of quartz and granite and usually have extensive applications in construction aggregates, dimension stone, geotechnical engineering, and petrology/geology. The elastic stress fields of inhomogeneous materials or composites inevitably change due to the presence of heterogeneous microstructure under applied external conditions, and hence the total mechanical and physical properties are affected by the temperature and pore pressure fluctuations beneath the surface. In this paper, the thermoporoelastic (TPE) approach on the basis of eigenstrain concept is introduced to predict the stress fields in fluid-saturated porous geologic materials like hydrocarbon reservoirs or aquifers by accounting for the coupling between thermal, poroelastic, and mechanical effects. It is an extension of the micromechanical theory that also incorporates thermal effects like pore pressure changes and temperature alternations. In addition, the TPE approach provides an important multiphysical modeling tool for understanding subsurface fluid-rock interactions and stress states in applications like unconventional oil/gas and geothermal energy.
