Abstract:
1. A coil tubing system, the system comprising: a reel having a core rotatable about a horizontal axis and a flange extending perpendicularly from each end of the core, the core having a surface defining an interior cavity, the flange has an opening for accessing the interior cavity, the core surface defining at least one opening therein, the opening on the core surface extending along the entire width of the core surface between each flange on the end of the core; a metallic oilfield coiled tubing having an inlet end and an inlet section, wherein the inlet end and inlet section are positioned substantially in the interior cavity, the inlet section extending from the inlet end to a core point located proximate the surface of the core in a form of a substantially arcuate curve, wherein the inlet end and the core point are offset from each other such that the inlet end and the core point are at different distances along the axis between the flanges, the coiled tubing disposed on the core surface when wrapped thereabout, the opening in the core surface providing access to inspect a bed wrap of the coiled tubing from the interior cavity; and a treating iron positioned proximate the horizontal axis of the reel and connected to the inlet end of the metallic oilfield coiled tubing.
