How does a coiled tubing unit work?
How does a coiled tubing unit work?
The coiled tubing is injected into the existing production string, unwound from the reel and inserted into the well. Coiled tubing is chosen over conventional straight tubing because conventional tubing has to be screwed together. Additionally, coiled tubing does not require a workover rig.
What is the advantage of using coiled tubing in intervention?
Advantages of using CT for well intervention Minimized formation damage when operation is performed without killing the well. Reduced service time as compared to jointed tubing rigs because the CT string has no connections to make or break. Increased personnel safety because of reduced pipe handling needs.

How do you calculate the volume of a tubing coil?
- Calculate rate of travel with coiled tubing.
- (Total bbl ÷ Pump rate in bbls/min = Total Minutes)
- (Total Interval in feet ÷ minutes = ft/min)
- To make 3 passes using same problem.
- To Calculate Pump Rate.
- (Bore2 x .7854 x Stroke x # of plungers)
