A Thermal-Sensitive Elastoplastic Semi-Analytical Solution for Wellbore Stability
To analyze an enhanced geothermal wellbore, a simple elastic perfectly plastic constitutive model is developed that uses the temperature-dependent yield surface. Based on the formulated constitutive model, a semi-analytical solution is developed for the circular wellbore. The results show that the elastoplastic model is capable of predicting the deformation and stresses response of borehole for both elastic to elastoplastic regions. This study can be further used for wellbore stability analysis.
