4.  Introduction
 What is Managed pressure drilling ?
is a technique used in the oil and gas industry to more precisely control the pressure within the wellbore
during drilling operations.
The idea is to keep the well's pressure within a narrow and safe range to avoid issues like kicks or formation
damage.

11. Advantages of M.P.D
 The main Value that MPD can Add in our Conventional drilling operations is:
Drill to the target while
 Saving Cost
 Reducing Non Productive time
 Improving safety
 How MPD does it ? We will Discuss further!

12. Optimized Well stability:
Conventional Drilling:
BHP = Mud Weight + Friction
MPD:
BHP= Mud Weight + Friction + Back Pressure

13. Other Advantages:
 Improved Safety
 Kick Detection and Well stability
 Reduced Formation Damage
 Enhanced Drilling Efficiency
 Better Hole Cleaning
 Environmental Benefits
 Improved Safety:
 Kick Detection and Well stability
 Reduced Formation Damage:
 Enhanced Drilling Efficiency:
 Better Hole Cleaning:
 Environmental Benefits:

14. In case of Conventional drilling:

15. In case of MPD:

16. Challenges Associated With MPD:
 Now Question?!
 If the MPD have so many advantages than Why is it not always applied instead of
convention drillings?

17.  Technical Complexity
 2. Initial Setup Costs
 3. Training Requirements
 4. Formation Uncertainties
 5. Fluid Compatibility
 6. Surface Equipment Limitations
 7. Environmental Considerations
 8. Data Interpretation
 9. Regulatory Compliance
 10. Risk of Equipment Failure
 11. Attitude of industry

18. Conclusion
 MPD a choice of Past and Necessity of Present
 MPD the “New Convention”
 Future Prospects and role of MPD
 Drill “Undrillable Wells”
“Transformation is not about technology at all, its about the People”
