Zusammenfassung:	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.
