Coiled Tubing Rigup
The main engine of a coiled tubing intervention is the injector head. This component contains the mechanism to push and pull the coil in and out of the hole. An injector head has a curved guide beam on top called a gooseneck which threads the coil into the injector body. Below the injector is the stripper, which contains rubber pack off elements providing a seal around the tubing to isolate the well's pressure.
Below the stripper is the blowout preventer, which provides the ability to cut the coiled tubing pipe and seal the well bore (shear-blind) and hold and seal around the pipe (pipe-slip). Older quad-BOPs have a different ram for each of these functions (blind, shear, pipe, slip). Newer dual-BOPs combine some of these functions together to need just two distinct rams (shear-blind, pipe-slip).
The BOP sits below the riser, which provides the pressurised tunnel down to the top of the Xmas tree. Between the Xmas tree and the riser is the final pressure barrier, the shear-seal BOP, which can cut and seal the pipe.

Famous quotes containing the word coiled:
“Now remember courage, go to the door,
Open it and see whether coiled on the bed
Or cringing by the wall, a savage beast
Maybe with golden hair, with deep eyes
Like a bearded spider on a sunlit floor
Will snarl—and man can never be alone.”
—Allen Tate (1899–1979)
