ABSTRACT

ABSTRACT: The analytical solution for an inclined borehole in a transversely isotropic poroelastic formation subjected to non-isothermal conditions is presented. The borehole is infinitely long and inclined to the far-field in situ stress direction and the borehole generator is assumed to coincide with the material axis of symmetry. The thermal perturbation is applied as a temperature gradient caused by a difference between the borehole fluid and formation temperatures. Numerical examples are given to demonstrate the effect of anisotropy of both poromechanical and thermic parameters on the stress and pore pressure response.
