Patent number: 8550185Abstract: A drill bit direction system and method is disclosed that modifies or biases the stochastic movement of the drill bit and/or stochastic interactions between the drill bit and an inner-wall of a borehole being drilled by a drilling system to change the direction of drilling of the drilling system. The direction of the drill bit is monitored to determine if the direction happens to align in some way with a preferred direction. If the direction isn't close enough to a preferred direction, a biasing mechanism modifies the stochastic movement in an attempt to modify the direction closer to the preferred direction. Any of a number of biasing mechanisms can be used. Some embodiments can resort to conventional steering mechanisms to supplement the biasing mechanism.Type: GrantFiled: October 19, 2011Date of Patent: October 8, 2013Assignee: Schlumberger Technology CorporationInventors: Ashley Bernard Johnson, Michael Charles Sheppard, Geoff Downton

Patent number: 8534380Abstract: This disclosure relates in general to a method and a system for directionally drilling a borehole with a rotary drilling system. More specifically, but not by way of limitation, methods and system provide for controlling motion of the rotary drilling system in the borehole when a side force is applied to the drilling system to bias or focus the motion so that the drilling system directionally drills the borehole through an earth formation. In certain aspects, side cutting of a sidewall of the borehole by a drill bit under an applied side force is controlled by a geostationary element to provide for directional side cutting and, as a result, directional drilling of the borehole through the earth formation. In other aspects, a non-concentrically coupled gauge pad assembly may rotate with the drilling system and bias or focus the applied side force.Type: GrantFiled: May 7, 2008Date of Patent: September 17, 2013Assignee: Schlumberger Technology CorporationInventors: Michael Charles Sheppard, Ashley Bernard Johnson, Geoff Downton
