Coiled Tubing Welds (Bias)
Bias Weld
Welded as flat strip: joints two strips. Traditionally used filler material
Till final length is reached
When tubing is formed, the weld takes the shape of a helix

Helical Lockup The distance to which the CT can be pushed into a
highly deviated or horizontal well is not the instant
when helical buckling occurs.
It has been shown experimentally and proven through
numerous field cases that the pipe can proceed
further, without damage, beyond what is the load for
helical buckling.
The maximum penetration depth is reached when the
applied force on the CT at surface can no longer
overcome the friction due to the helical wall contact
forces.
This situation is called “helical lockup”.

CT Reel – Functions
Basic functions of the reel:
Storing and protecting the CT string – reel
drum (1)
Maintaining proper tension between reel and
injector head (reel drive system)
Efficiently spooling the CT string onto the
reel drum - levelwind system (2)
Circulating fluids with the drum rotating –
swivel (3)
Application of protective coating or inhibitor
on tubing string - tubing lubricator system
(4)
CT depth measurement system - reel
mounted counter and integrity monitor (5)This is always the heaviest load. Determines logistics and applicability in many situations !

Injector Head – FunctionsBasic functions of the injector head or equipment
normally mounted on the injector head include:
Injecting and retrieving the CT string
Holding the CT string static
Guiding the CT to the reel
Tension/compression measurement (weight indicator)
Depth/speed measurement (depth system sensor)
Mounting place for primary pressure barrier (stripper)
