Wellbore Stability and Rock Mechanics


This course is designed to explain problems related to borehole stability using modern Rock Mechanics techniques. The course is suitable for both drilling and petroleum engineers


To provide a thorough understanding of wellbore stresses, principles of rock mechanics and wellbore stability. To be able to calculate safe mud weights. Use well logs to determine essential rock properties.


  • Rock behaviour and measurement of rock properties
  • Basic stresses and strains
  • Stresses due to drilling a well
  • Stress transformations for horizontal and multi-lateral wells
  • Mohr envelope
  • Failure criteria
  • Triaxial rock testing
  • Borehole rupture mechanics
  • Hole collapse mechanisms
  • Safe mud weights envelope
  • Earth stress measurements
  • Stuck pipe problems
  • Designing a perfect well with the earth stresses
  • Effects of reservoir compaction
  • Production effects
  • Sand production
