Scenario: You are the drilling engineer for a new oil well. Your team is about to start drilling and you have received the following information:
Task:
**1. Analysis:** * The existing wellbore is located relatively close to the new well, increasing the probability of collision. * The existing wellbore deviates from vertical, suggesting it could intersect with the new wellbore at a depth shallower than the target depth. * The surveying data identifies a potential collision zone at 2,500 meters, which is within the drilling range of the new well. **2. Preventative Measures:** * **Trajectory Adjustment:** Modify the planned trajectory of the new wellbore to avoid the identified collision zone. This can be achieved by adjusting the drilling angle and/or direction. * **Advanced Monitoring:** Implement real-time downhole monitoring and analysis to detect any deviations from the planned trajectory. This allows for early intervention to correct course and avoid a collision. **3. Suitability:** * **Trajectory Adjustment:** Adjusting the trajectory is a practical and effective solution for avoiding the collision zone identified by the surveying data. * **Advanced Monitoring:** Real-time monitoring provides continuous feedback and allows for immediate adjustments if the drill bit deviates from the planned path, ensuring a safe drilling operation.
