ABSTRACT:
A conventional drilling system using continuous coiled tubing connected to a reel at its upper end and connected to a drilling tool at its lower end is steered by rotating the injector at the well head which drives the tubing into the well about an axis longitudinal of the well bore to effect twist in the tubing along the well bore and thus to rotate the drilling tool. This twist in the tubing between the injector and the reel is negated by rotating the reel about a vertical axis parallel to the well bore in a direction, viewed from above, which is opposite to the direction of the injector.
