Publication number: 20110042149Abstract: Methods of forming polycrystalline diamond elements include forming a polycrystalline diamond element. A Group VIII metal or alloy catalyst is employed to form the polycrystalline diamond compact table at a pressure of at least about 6.5 GPa or greater. The catalyst is then removed from at least a portion of the table to a depth from a working surface thereof, and may be removed from the entirety of the table. Polycrystalline diamond elements include such polycrystalline diamond compact tables. Earth-boring tools include such polycrystalline diamond elements carried thereon and employed as cutting elements.Type: ApplicationFiled: August 18, 2010Publication date: February 24, 2011Applicant: BAKER HUGHES INCORPORATEDInventors: Danny E.

Patent number: 7757784Abstract: A novel well bore drilling system and method utilizes independently deployable multiple tubular strings to drill, line and cement multiple hole sections without intervening trips to the surface. In one embodiment, the drilling system includes two or more independent, telescoping, tubular members that form a nested tubular assembly and one or more sensors disposed on the nested tubular assembly. The nested tubular string is deployed in the wellbore in conjunction with a Bottom Hole Assembly (BHA). In some embodiments, a drilling motor for rotating a drill bit is also positioned in the tubular assembly. The sensors can be disposed in a stator of the drilling motor or adjacent the motor. Also, in embodiments, the sensors can be positioned on extensible members that can position the sensor or sensors adjacent the wellbore wall.Type: GrantFiled: June 24, 2005Date of Patent: July 20, 2010Assignee: Baker Hughes IncorporatedInventors: Roger Fincher, Allen Sinor, Larry Watkins, Joel Wilmes

Patent number: 7730970Abstract: A device and system for improving efficiency of subterranean cutting elements uses a controlled oscillation super imposed on steady drill bit rotation to maintain a selected rock fracture level. In one aspect, a selected oscillation is applied to the cutting element so that at least some of the stress energy stored in an earthen formation is maintained after fracture of the rock is initiated. Thus, this maintained stress energy can thereafter be used for further crack propagation. In one embodiment, an oscillation device positioned adjacent to the drill bit provides the oscillation. A control unit can be used to operate the oscillation device at a selected oscillation. In one arrangement, the control unit performs a frequency sweep to determine an oscillation that optimizes the cutting action of the drill bit and configures the oscillation device accordingly. One or more sensors connected to the control unit measure parameters used in this determination.Type: GrantFiled: September 6, 2007Date of Patent: June 8, 2010Assignee: Baker Hughes IncorporatedInventors: Roger W. Fincher, Larry A. Watkins, Peter Aronstam, Allen Sinor, John L. Baugh

Patent number: 7703558Abstract: A drilling tool including at least two cutting elements (e.g., redundant or upon a selected profile region) sized, positioned, and configured thereon so as to contact or encounter a change in at least one drilling characteristic of a subterranean formation along an anticipated drilling path prior to other cutting elements thereon encountering same is disclosed. Methods of designing a drilling tool are also disclosed including placing such cutting elements upon the cutting element profile in relation to a predicted boundary surface along an anticipated drilling path. Methods of operating a drilling tool so as to initially contact a boundary surface between two differing regions of a subterranean formation drilled with at least two cutting elements is disclosed. The cutting elements configured on drilling tools and methods of the present invention may be designed for limiting lateral force or generating a lateral force having a desired direction during drilling associated therewith.Type: GrantFiled: August 22, 2008Date of Patent: April 27, 2010Assignee: Baker Hughes IncorporatedInventors: L.
