Which Tools Are Used To Recover A Stuck Pipe?

Many times, a pipe gets blocked during drilling or digging processes of a well. It may be due to excessive pressure on the pipe from outside, friction, tight wellbore, etc.

However, you can separate the blocked part from the free portion of a pipe by using any of these cutting tools-

Precision Tubular Cutter

A tubular cutter can be used in all types of fluid environment, including dry gas. It severs the tubing or casing that allows pipe recovery in the upper tubular sections of a wellbore. This revolutionary cutter can cut through the scaled, corroded, or plastic-coated pipe. Therefore, you don’t require additional string shots before pipe-cutting operations.

It provides simple, efficient operation of a jet cutter along with a clean and smooth cut. As this tool cuts tubing without any need for an overpull, it is also ideal for tailpipe cutting.

By reducing the possibility of sticking in the tubing, it eliminates the HSE (health, safety, and environment) issues. Also, it saves rig time and cuts down operation costs as well.

Chemical Clutter

Whether it is drilling or workover operations, a stuck pipe causes several problems. A chemical cutter is an innovative tool that helps you to cut off by the action of chemical reactions.

There is nozzle head on the tool through which the chemical goes down into wellbore. As the fluid comes in contact with the metallic pipe, an exothermic reaction takes place. The heat released as a result of the reaction cuts the pipe from the blocked end.

These cutters provide fine cuts without causing any damage to the well casing or adjacent pipe. This special tool can be used for any special cutting applications when other methods may be ineffective.

Mechanical Cutter

A mechanical pipe cutter reduces environmental and logistical constraints, providing precise downhole pipe cutting. You can attach this tool with electric wireline services and drop it down into the wellbore. They perform electromechanical rotations to cut the stuck pipe inside the well.

This tool can be used to recover the stuck pipe in a hotter environment while eliminating expensive coiled-tubing operations. It is best suited for alloy pipes, soft pipes, and gives precise cutting without any residual debris.

Radial Cutting Torch

It is another patented cutting device used to drill pipe, sever tubing or casing. First, the torch is lowered into the wellbore at the desired depth. There is a thermal generator that activates the mixture of powdered metal and converts it into molten plasma.

When the pressure inside the torch exceeds than that of the wellbore, the nozzle ejects out plasma at the target. In this way, it separates the blocked portion of pipe. It is one of the safest pipe cutting alternatives to hazardous chemicals and explosives.

Abrasive Pipe Cutter

Abrasive cutters use particulate such as glass beads, calcium carbonate, and sand to cut the stuck pipe. When the particulate pumped on the blocked site rotates at the same place for some time, it cuts the pipe.

It provides clean cuts without heat build-up and thermal distortions. Also, it is easy to use, flexible to adjust to save labor, and maximize productivity.

Jet Cutter

It is a circular-shaped tool that can make 360 degrees cut at the stuck pipe in the downhole instead of high pressure inside the walls. Due to its short length, it is best suited for a stuck point at a limited height.

The type of particulate to be put in its nozzle depends upon the pressure, temperature, and height of the jammed pipe.

Conclusion

These are some of the most commonly used pipe recovery tools. You can use any one of these attachments to separate the stuck portion of the pipe during the drill rig applications.
