The concept of poroelasticity is of particular importance in the fields of rock mechanics and wellbore stability. It integrates the
effects of the pore fluid into the mechanical response of an earth material and allows the interpretation of time-dependent phenomena.
The purpose of this thesis is to study the general equations governing the mechanical stability of a borehole located in a poroelastic formation. The simple case of an isotropic rock will be first reviewed, followed by the more complicated case of a transverse isotropic rock.
