Coil Tubing Drilling Accessory

18 May 2010 Has anyone any knowledge of and in addition experience of a tool used in drilling with coil tubing that allows a motor, mwd and bent sub assembly to be indexed around to point the bit in the right place for directional drilling when the coil tubing itself cannot be rotated. It is likely to be a form of mechanical indexing sub in its simpliest form and may be available in an electrically driven form as well. Any information or track record of such a tool would be greatly appreciated.
