Coiled Tubing

Definition - What does Coiled Tubing Equipment mean?

Coiled tubing is a long metal pipe that is surrounded or rolled over a large reel that is brought to the well site when any well repair or workover activities are to be performed. There are no joints in between the coiled tube which means that it’s a continuous long metal pipe that can be taken inside the borehole to the depth of up to 15000 feet.

Bracetool explains Coiled Tubing

The diameter specifications of coiled tubing varies according to the diameter of the wellbore. The diameter of the CT pipe ranges from 25 to 85 mm, roughly, 1 to 3.5 inches.

Coiled tubing helps in improving the well & reservoir performance. There are wide range of operations on the site that makes use of coiled tubing such as:

  • Milling
  • Drilling
  • Rock fracturing
  • Sidetracking
  • Production tubing
  • Low bottomhole pressure drilling
  • Wellbore cleanout
  • Nitrogen kickoff
  • Sand control
  • Cementing
  • Mechanical isolation
  • Tube Logging & perforating
Before the CT pipe is pushed into the wellbore, it is uncurled from the reel and straighten up. These coiled pipes are suitable for the use in the onshore as well as offshore oil well locations.
