Scenario: You are working on an oil rig, and a sudden surge in pressure is detected in a well. The drilling crew is alerted, and they activate the BOP.
Task: 1. List the key steps you would expect to happen when the BOP is activated to control the situation. 2. Describe the importance of each step in preventing a blowout.
1. **Key steps when BOP is activated:** * **Closure of the Annulus Preventer:** This seals off the space between the drill string and the wellbore, preventing further fluid flow. * **Closure of the Blind Shear Rams:** These rams completely seal off the wellbore, stopping any further flow. * **Activation of the Choke Manifold:** The choke manifold is used to control the flow of fluids, diverting them to a safe location or reducing the flow pressure. * **Monitoring and Evaluation:** Constant monitoring is crucial to ensure the BOP is effectively controlling the well pressure. 2. **Importance of each step:** * **Annulus Preventer:** Prevents fluid from escaping the wellbore through the space around the drill string, reducing the risk of uncontrolled flow. * **Blind Shear Rams:** Provide a complete seal, stopping all fluid flow and preventing a full-blown blowout. * **Choke Manifold:** Enables controlled flow, reducing the risk of explosions and allowing for safe disposal of released fluids. * **Monitoring and Evaluation:** Ensures the BOP system is functioning effectively and allows for immediate action if any issues arise.
