Introduction
Le Kinley Caliper™, un outil spécialisé utilisé dans l'industrie pétrolière et gazière, joue un rôle crucial dans le maintien de l'intégrité et de la sécurité des puits. Ce calibre multi-doigts est conçu pour fournir des mesures détaillées du diamètre intérieur (ID) du tubage, identifiant les problèmes potentiels pouvant entraîner des fuites, des éruptions et des dommages environnementaux.
Kinley Caliper™ : Un aperçu plus approfondi
Le Kinley Caliper™ est un outil de fond de puits déployé sur un câble ou un tube enroulé. Il se compose généralement de plusieurs doigts à ressort qui s'étendent vers l'extérieur, entrant en contact avec la paroi du tubage. Chaque doigt est équipé d'un capteur qui mesure avec précision la distance entre l'axe central de l'outil et la paroi du tubage.

Scenario:
You are an engineer working on a well project. The Kinley Caliper™ data reveals a significant reduction in casing inner diameter (ID) in a specific section of the wellbore.
Task:
Possible Causes: * **Corrosion:** Internal corrosion can eat away at the casing wall, reducing the inner diameter. * **Pitting:** Localized corrosion forming pits on the casing wall can also reduce the overall ID. * **Scale Build-Up:** Mineral deposits can build up on the inner casing surface, reducing the ID. * **External Damage:** Mechanical damage from tools or debris could have caused a dent or deformation reducing the ID. Potential Risks: * **Tubing Hang-Up:** The reduced ID might make it difficult or impossible to run tubing through the well. * **Cementing Issues:** Reduced ID could affect the effectiveness of cementing operations. * **Leakage:** The weakened casing due to corrosion or pitting can lead to leakage. * **Blowout:** In extreme cases, severely compromised casing could lead to a blowout. Actions to Take: * **Further Investigation:** Run additional logging tools like a caliper log, ultrasonic inspection, or a production logging tool to further assess the damage and its extent. * **Well Intervention:** Consider remedial actions like: * **Casing Repair:** Depending on the nature and severity of the damage, a casing repair operation may be necessary. * **Casing Replacement:** In cases of severe corrosion or damage, a replacement of the casing may be required. * **Well Abandonment:** In extreme cases, if the well is considered unsafe or beyond repair, well abandonment might be the only option. * **Risk Assessment:** Conduct a thorough risk assessment to understand the full implications of the reduced ID and plan for safe and effective mitigation.
