20110042144 | STEERABLE DRILLING SYSTEM - A steerable drilling system comprising a bottom hole assembly ( | 02-24-2011 |
20110056695 | VALVES, BOTTOM HOLE ASSEMBLIES, AND METHOD OF SELECTIVELY ACTUATING A MOTOR - Aspects of the invention provide valves, bottom hole assemblies, and methods of selectively actuating a motor. One aspect of the invention provides a valve including: a barrel having an interior having a circular cross-section, an inlet port, an outlet port, and a by-pass port; a first disc rotatably received within the barrel; and a second disc rotatably received within the barrel and pressed against the first disc to selectively form a seal. The first disc and the second each have an orifice. | 03-10-2011 |
20110139508 | GAUGE 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 |
20110139512 | ACTUATORS, 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 |
20110308862 | DRILLING SYSTEM - A drilling system comprising a rotatable drill pipe | 12-22-2011 |
20120292110 | SYSTEM AND APPARATUS FOR MODELING THE BEHAVIOR OF A DRILLING ASSEMBLY - A method for drilling a borehole includes obtaining, while drilling the borehole, sensor data for the drilling assembly, analyzing, while drilling the borehole, the sensor data using a drilling behavior model to obtain results, and adjusting the drilling of the borehole based on the results. The drilling behavior model models drilling of the borehole using a distance drilled, a number of touch points, a number of bend angles, a number of external moments, a number of lengths of distributed weights, a lateral displacement of a center of the borehole at a bit, at least one vertical displacement from the center of the borehole, at least one angular offset, at least one force, and at least one mass per unit length. | 11-22-2012 |
20130112483 | Oil Operated Rotary Steerable System - 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. | 05-09-2013 |
20130341098 | Directional Drilling System - A technique facilitates drilling of wellbores or other types of bore holes in a variety of applications. A steerable system or other well tool is designed with a plurality of actuators which are positioned to provide controlled steering during a drilling operation. Each actuator includes at least one loose element or ball slidably mounted in a corresponding sleeve. Pressurized fluid is used to provide controlled movement of the elements along the corresponding sleeves of the actuators. The controlled movement of the elements assists in the provision of steering or other control over the well tool during the drilling operation. | 12-26-2013 |
20140131099 | System And Method For Managing And/Or Using Data For Tools In A Wellbore - A system and a method manage and use data related to a wellbore or a drill string. The system and the method may provide remote access to tools in a drill string using a network. In addition, the tools have access to the data. In a disclosed embodiment, the tools are able to automatically access the data needed to optimize or improve function of the tools. | 05-15-2014 |
