... ABSTRACT: This study investigates the thermal–mechanical behavior of slates in geothermal reservoirs and establishes an anisotropic thermal–mechanical coupling failure criterion. Slate samples obtained from a geothermal site were subjected to a series of direct-shear and triaxial-compression...

... environment of the field. The new method incorporates the Mogi-Coulomb criterion, which considers intermediate stress as the shear failure criterion of the wellbore. Additionally, the method accounts for the shear breakdown of rock when calculating the fracture pressure. It predicts the shear slip...

It should be emphasized that the end of the pure elastic deformation does not indicate the failure of the rock mass around the wellbore. Furthermore, an allowable tolerance plastic yielding around the wellbore induced by the drilling...

The maximum tensile stress criterion was modified considering the influence of confining pressure, which was incorporated into ABAQUS, and characteristics of hydraulic fractures under different in-situ stress conditions were studied. The results reveal that (1) under the confining...
