20090044977SYSTEM AND METHOD FOR CONTROLLING A DRILLING SYSTEM FOR DRILLING A BOREHOLE IN AN EARTH FORMATION - This disclosure relates in general to a method and system for controlling a drilling system for drilling a borehole in an earth formation. More specifically, but not by way of limitation, embodiments of the present invention provide systems and methods for controlling dynamic interactions between the drilling system for drilling the borehole and an inner surface of the borehole being drilled to steer the drilling system to directionally drill the borehole. In another embodiment of the present invention, data regarding the functioning of the drilling system as it drills the borehole may be sensed and interactions between the drilling system for drilling the borehole and an inner surface of the borehole may be controlled in response to the sensed data to control the drilling system as the borehole is being drilled.02-19-2009

20100101864ANTI-WHIRL DRILL BITS, WELLSITE SYSTEMS, AND METHODS OF USING THE SAME - A wellsite system includes a drill string suspended within a borehole, anti-whirl drill bits for use in the system, and methods of drilling a curved borehole in a subsurface formation. The drill bit can have an interior cavity in fluid communication with the drill string and a first gauge pad located on the exterior of the drill bit. The first gauge pad includes a first orifice in fluid communication with the interior cavity, where the first orifice is arranged at an angle relative to cutters fixed to the drill bit. The drill bit is configured such that a fluid continuously flows from the first orifice.04-29-2010
20100101867SELF-STABILIZED AND ANTI-WHIRL DRILL BITS AND BOTTOM-HOLE ASSEMBLIES AND SYSTEMS FOR USING THE SAME - A wellsite system includes a drill string suspended within a borehole, and a bottom hole assembly with a drill bit at its lower end, where the drill bit is a self stabilized and anti-whirl drill bit. The drill bit includes an interior cavity in fluid communication with the drill string, and a plurality of gauge pads located on the exterior of the drill bit. One or more of the gauge pads include an orifice in communication with the interior cavity, where the orifice is arranged at an angle relative to cutters fixed to the drill bit. The drill bit is configured such that a fluid continuously flows from each of the orifices.04-29-2010
20100139983ROTARY STEERABLE DEVICES AND METHODS OF USE - The invention provides rotary steerable devices and methods for use of rotary steerable devices. One aspect of the invention provides a rotary steerable device including: a cylinder configured for rotation in a wellbore, the cylinder having a slot and a gauge; and at least one cam received in the slot. The cam is configured for selective actuation between a first position, wherein the cam lies within the gauge of the cylinder, and a second position, wherein the cam is displaced out of the gauge of the cylinder.06-10-2010
20110139508GAUGE PADS, CUTTERS, ROTARY COMPONENTS, AND METHODS FOR DIRECTIONAL DRILLING - The present invention recites a method, system and apparatus, wherein said method, system and apparatus comprises a gauge pad for a rotary component received within a borehole, the gauge pad comprising an exterior surface dimensioned for rotation in close proximity to the borehole, a pocket extending through the exterior surface, the pocket in fluid communication with a pressurized fluid source, and wherein the exterior surface is dimensioned such that when a pressurized fluid is discharged through the pocket, the velocity of the fluid through a gap between the exterior surface and borehole creates a pressure drop sufficient to pull the rotary component toward the gauge pad.06-16-2011
20110139512ACTUATORS, ACTUATABLE JOINTS, AND METHODS OF DIRECTIONAL DRILLING - The present invention recites a method and apparatus, wherein said methods and apparatus comprises an actuator comprising a first plate, a pocket extending through the first plate, the pocket in fluid communication with a pressurized fluid source and a second plate coupled to a component that is to be actuated, wherein the first plate, the second plate, and the pocket are dimensioned such that when a pressurized fluid is discharged through the pocket, the velocity of the fluid through a gap between the first plate and the second plate creates a pressure drop sufficient to pull the second plate toward the first plate.06-16-2011
