The friction reduction tools itself to produce longitudinal vibration to improve weight transfer in the drilling process effectiveness and reduce the friction between the drill and hole at the bottom, this means that drilling with tool can be used in a variety of modes, particularly in power drilling directional drilling is used to imporve weight transfer, reducting the likehood of BHA sticking to reduce torsional vibration and borehole wall friction, reduce stick-slip vibration in the drilling process, increase the penetration reate and extended bit life, and possibly guide and motor coordination, to improve control of the tools.
