Abstract
Coiled tubing or a portion thereof having a first part spaced-apart from a second part, the coiled tubing having a first outer diamter at the first part and a second outer diameter at the second part, the first outer diameter different from the second outer diameter, and outer diameter of the coiled tubing continuously diminishing or increasing from the first part to the second part, in one particular aspect thus varying over its entire length; and methods for using and methods and apparatuses for making such coiled tubing.
Claims16
Coiled tubing comprising a first end spaced-apart from a second end,
- the coiled tubing having a first outer diamter at the first end and a second outer diameter at the second end,
- the first outer diameter larger than the second outer diameter, and
- outer diameter of the coiled tubing continuously diminishing from the first end to the second end.
Coiled tubing comprising a first end spaced-apart from a second end and an intermediate portion between the first end and the second end,
- the coiled tubing having a first outer diameter at the first end, a second outer diameter at the second end, and
- a third outer diameter at the intermediate portion, and
- outer diameter of the coiled tubing continuously varying from the first end to the intermediate portion.
