“…Recently in the literature, there have been many studies on the stress state of the wellbore. Whilst Kanfar et al [7], Do et al [8,9], Tran et al [10], Khoshghalb [11,12], Ghaffaripour et al [13], and Shafee and Khoshghalb [14] relied on the hydro-mechanical behavior model, Abousleiman and Ekbote [15] and Kanfar et al [16] based on a full thermo-hydromechanical behavior model of the materials. However, these works mainly focus on the development of analytical and numerical models without emphasizing the difference in stress state around the wellbore between the cases of cooling and heating as well as different anisotropy degrees of the rocks.…”
