Abstract: The drill string is fitted for drilling activity in the formation expected, including a jet nozzle equipped drill head, and a near bit kick sub. The drill string is deflected to change the progressing well bore to a preferred direction. After the change in well bore direction is accomplished by jetting, the kick sub is straightened and drilling proceeds along the new well bore center line. Ideally, the kick sub responds to direction from the surface and produces a change in drilling fluid pressure at the surface to indicate which mode, straight or deflected, is being carried out down hole.
