Geomechanics

Appropriate assignment of mud pressure while drilling is required to ensure borehole stability. The simulation investigate the development conditions for borehole breakout and drilling induced tensile fractures in a vertical borehole.

Learning Outcomes

• Simulate the development of borehole breakouts and drilling induced tensile fractures in a vertical borehole.
• Investigate the influence of different stress regimes on the development of borehole failure.
• Explore the effect of mud pressure and effective rock strength on the borehole stability.
