What is coiled tubing used for?

Coiled tubing is a continuous length of tubing that is wound on a large spool. It is used in various industries for a variety of applications. Some of the common uses of coiled tubing include:

 

1. Oil and Gas Industry:
Well Intervention: Coiled tubing is often deployed in oil and gas wells for interventions such as cleanouts, scale removal, acidizing, and hydraulic fracturing.
Drilling Operations: Coiled tubing can be used for drilling certain types of wells, particularly in unconventional reservoirs.

 

2. Geothermal Industry:
Coiled tubing is used in geothermal wells for interventions and maintenance activities similar to those in the oil and gas industry.

 

3. Mining Industry:
In mining, coiled tubing is employed for activities such as drilling, blasting, and dewatering in underground mines.

 

 

4. Chemical and Petrochemical Industry:
Coiled tubing is utilized for conveying various chemicals and fluids in industrial processes.

 

5. Water Well Drilling:
Coiled tubing can be used in water well drilling operations, providing a continuous and flexible tube for accessing underground water sources.

 

6. Pipeline Services:
Coiled tubing is used for pipeline cleanouts and inspections, providing a flexible and efficient means of accessing and servicing pipelines.

 

7. Environmental and Geotechnical Applications:
Coiled tubing is sometimes used for environmental monitoring and remediation activities, as well as in geotechnical drilling applications.

 

8. Research and Development:
Coiled tubing is employed in various research and development projects for testing and experimentation purposes.

 

The versatility of coiled tubing lies in its ability to be spooled onto a reel, making it easy to transport and deploy in various applications. The choice of coiled tubing over conventional tubing or pipe is often driven by its flexibility, continuous length, and the ability to perform various downhole operations without the need for jointed pipe sections.
