How does a coiled tubing unit work?
How does a coiled tubing unit work?
The coiled tubing unit is composed of a reel with the coiled tubing, an injector, control console, power supply and well-control stack. The coiled tubing is injected into the existing production string, unwound from the reel and inserted into the well.

What is the advantage of using coiled tubing in interventions?
Significant Advantages Coiled tubing can help the operator avoid the risk of formation damage inherent in killing a well by allowing continuous circula- tion during well intervention operations. These advantages may yield sig- nificant cost savings over conventional drilling or workover techniques.
What is coiled tubing stripper?
Stripper/packer is a primary barrier in a coiled tubing unit and the stripper is designed to provide a pressure seal around a coiled tubing unit when it is being run into or pulled out of a live well. The sealing mechanism is activated by hydraulic pressure controlled by an operator.
What is a coil tubing operator?
The Coil Tubing Operator coordinates and directs the activities of the assistants during the rig up and down of service line equipment and the assembly and preparation of equipment for installation, service and running of a job.
Why is coiled tubing used?
Coiled tubing applications include drilling operations, hydraulic fracturing, well completions, removing sand or fill from wellbore, and other applications that involve pumping fluids at high temperatures and high salinity.
What is coiled tubing string?
1. n. [Well Workover and Intervention] A continuous length of low-alloy carbon-steel tubing that can be spooled on a reel for transport, then deployed into a wellbore for the placement of fluids or manipulation of tools during workover and well-intervention operations.
How is coiled tubing made?
Coiled tubing technology involves coiled tubing twisted on a drum that can be continuously withdrawn or lowered from the well without connecting thread. The coiled tubing is made of high-strength, low-alloy materials, which first is rolled straight and then welded together.
