Abstract:
1. A system for drilling a wellbore, comprising: a drill bit; a steering tool coupled to the drill bit; and an orienting tool coupled to the steering tool on a side opposite the drill bit, the orienting tool comprising a piston cooperating with a spline member within a housing to selectively change the rotational position of the orienting tool, the piston being a floating piston cooperating with a floating nut to facilitate directional drilling of the wellbore regardless of a curvature of the orienting tool, wherein the spline member is disposed through the floating nut and wherein axial translation relative to the spline member and the floating nut imparts rotational motion relative to the spline member and the housing and wherein the floating nut is not radially secured to the housing or the spline member.
