Re-Entry Spool Exercise
Scenario: You are an engineer tasked with selecting a Re-Entry Spool for a well intervention. The well operates at a pressure of 10,000 psi and requires a connection for running a wireline tool.
Task:
- Identify two key factors to consider when selecting a Re-Entry Spool for this specific application.
- Explain how these factors relate to the well's operating pressure and the wireline tool connection.
- Provide a brief justification for your choices.
Exercice Correction
1. **Pressure Rating:** The spool must have a pressure rating that exceeds the well's operating pressure of 10,000 psi to ensure safe and reliable operation. A lower pressure rating could lead to catastrophic failure during intervention. 2. **Connection Profile:** The spool's connection profile must be compatible with the wireline tool being used for the intervention. This ensures a secure and leak-proof connection during operations. 3. **Justification:** The pressure rating ensures the spool can withstand the well's pressure without failure, while the connection profile guarantees compatibility with the specific wireline tool used for the intervention, minimizing risk of leaks and ensuring a successful operation.
