Mechanical External Cutter

Application Scenarios 1. Well Intervention and Workover When tubulars are stuck, damaged, or need to be removed during well maintenance, the cutter helps isolate and cut the problematic section to facilitate recovery or replacement. 2. Abandonment and Plugging Operations During well abandonment, it cuts casing or tubing to prepare for plug placement, ensuring proper well closure. 3. Emergency Pipe Recovery In cases where stuck pipes cannot be retrieved intact, the cutter severs the tubulars to retrieve upper sections and minimize operational delays.

Key Functions

- Precision Cutting

It engages with the external wall of the tubular and uses mechanical force (e.g., rotational torque or hydraulic pressure) to cut through metal, allowing controlled separation of pipe sections.

- Compatibility with Various Tubular Sizes

Designed to fit different outer diameters of casing or tubing, making it versatile for various wellbore configurations.

- Combination with Other Tools

Often used with jars or fishing tools to align, stabilize, and cut tubulars efficiently, especially in complex downhole environments.

- Reduction of Operational Risks

By enabling targeted cutting, it avoids the need for more invasive methods (e.g., explosive cutters), minimizing the risk of wellbore damage or safety hazards.

In summary, the Mechanical External Cutter plays a critical role in resolving stuck-pipe issues, supporting well maintenance, and ensuring safe, efficient operations during drilling, workover, or abandonment processes.
