1. Well Control in Drilling Fundamentals, Methods, and Safety Practices

2. Introduction What is well control? Importance in drilling operations Consequences of poor well control (safety, environment, cost)

3. Fundamentals of Pressure Hydrostatic pressure Formation pressure Bottomhole pressure (BHP) Pressure balance concept (Primary well control)

4. Causes of Well Control Issues Insufficient mud weight Lost circulation Swabbing during tripping Equipment failure

5. Kick Indicators Increase in pit volume Flow rate changes Change in drill string weight (drag, torque) Gas-cut mud, mud weight decrease

6. Well Control Methods Primary: Proper mud weight Secondary: Blowout Preventer (BOP) Tertiary: Relief wells, capping stacks

7. Blowout Preventer (BOP) Types: Annular, Ram, Blind/Shear Function and role in shutting in a well

8. Well Shut-in Procedures Driller’s method Wait-and-weight method Safety checks before and during shut-in

9. Case Study: Deepwater Horizon 2010 Macondo blowout Causes: Cement failure, pressure mismanagement Lessons learned

10. Safety Practices & Training Kick drills Well control certification (IWCF, IADC) Crew communication & preparedness

11. Conclusion Prevention > Response Importance of continuous training and monitoring
