Abstract
A coiled tubing assembly includes coiled tubing conveyable into a wellbore, a rotational device operatively coupled to the coiled tubing, a rotatable tubing segment operatively coupled to the rotational device, and a bottom hole tool arranged at an end of the rotatable tubing segment opposite the rotational device. The rotational device rotates the rotatable tubing segment relative to the coiled tubing as the coiled tubing, the rotatable tubing segment, and the bottom hole tool are axially displaced along the wellbore.

A coiled tubing assembly, comprising:
- coiled tubing conveyable into a wellbore;
- a rotational device operatively coupled to the coiled tubing;
- a rotatable tubing segment operatively coupled to the rotational device;
- and
- a bottom hole tool arranged at an end of the rotatable tubing segment opposite the rotational device,
- wherein the rotational device rotates the rotatable tubing segment relative to the coiled tubing as the coiled tubing, the rotational tubing segment, and the bottom hole tool are axially displaced along the wellbore.
A method of performing a coiled tubing operation in a wellbore, comprising:
- introducing a coiled tubing assembly into the wellbore, the coiled tubing assembly comprising;
- coiled tubing;
- a rotational device operatively coupled to the coiled tubing;
- a rotatable tubing segment operatively coupled to the rotational device;
- and
- a bottom hole tool arranged at an end of the rotatable tubing segment opposite the rotational device;
- powering the rotational device to rotate the rotatable tubing segment;
- and
- simultaneously conveying the coiled tubing assembly axially along the wellbore while rotating the rotatable tubing segment.
