Apparatus for bending a coiled tubing, the apparatus having a head portion for lateral insertion in a side opening in a wall of a well, the head portion defining a bending path for bending the coiled tubing during feeding thereof through the head portion, and the head portion having a coiled tubing straightener for straightening the coiled tubing during said feeding, the coiled tubing straightener being retractable so that it can adopt a retracted position, for lateral insertion of the head portion into the side opening of the well wall, the head portion having, when the straightener is in the retracted position, a profile as viewed in the direction of lateral insertion, and the straightener being extendable for operation to straighten the coiled tubing to an extended position at least partly outside of said profile of the head portion. |
