A technique facilitates steering of rotary steerable systems when conducting directional drilling operations. A rotary steerable system is combined with a pressurized oil system which delivers oil to a piston actuated mechanism. The pressurized oil provides precise, long-lasting control over the orientation of the bottom hole assembly and the drill bit to facilitate directional drilling of boreholes through subterranean formations.
