Instructor:

Dr Saad Saleh, H. Rabia

Course Duration:

One week

Highlights:

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

Objectives:

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. 

Content:

• 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
