A finite-element model is developed for simulating wellbore strengthening.
- class="label">•
Effects of various parameters on wellbore strengthening are examined.
- class="label">•
Hoop stress around the wellbore can be increased by bridging the fracture.
- class="label">•
The best place to bridge the fracture is the fracture mouth near the wellbore wall.
- class="label">•
Several other useful field implications for wellbore strengthening are provided.
