Abstract

A method and apparatus for steering a drilling assembly (200) during drilling operations for oil and gas. The steering assembly being disposed in a borehole (10) and comprising a drill bit (120) attached to a drill collar (210) having an eccentric stabilizer (220) disposed thereupon. The eccentric stabilizer either in an engaged state whereupon rotating concentrically with the drill collar, or in a released state whereupon as the drill collar rotates the eccentric stabilizer is positioned eccentrically relative to the drill collar creating a lateral deflection in the borehole that may be used for changing the direction of the drilling assembly.
