Thermoporoelastoplastic Wellbore Breakout Modeling by Finite Element Method

Thermoporoelastoplastic Wellbore Breakout Modeling by Finite Element Method

Drilling a hole into rock results in stress concentration and redistribution close to the hole. When induced stresses exceed the rock strength, wellbore breakouts will happen. Research on wellbore breakout is the fundamental of wellbore stability. A wellbore breakout is a sequence of stress concentr...
