Patent number: 8474527Abstract: A mechanism for adjusting the relative angular orientation of two coaxial components includes a mandrel having a cylindrical central section between upper and lower splined sections, a sleeve rotatably and slidably disposed around the mandrel's central section, and generally cylindrical upper and lower ratchet members positioned, respectively, about the mandrel's upper and lower splined sections. The ratchet members have internal grooves which receive the mandrel splines for torsional load transfer while permitting limited rotation relative to the mandrel, but their axial positions relative to the mandrel are fixed. The upper and lower ends of the sleeve have circumferentially-arrayed ratchet teeth engageable, respectively, with corresponding teeth on the upper and lower ratchet members. The central sleeve has torque-transferring external splines slidable within matching grooves on the inner surface of a cylindrical tool housing enclosing the mechanism.Type: GrantFiled: May 28, 2009Date of Patent: July 2, 2013Assignee: Dreco Energy Services Ltd.Inventors: Jonathan Ryan Prill, Nicholas Ryan Marchand

Publication number: 20130161027Abstract: A downhole actuation system comprises an actuation mechanism comprising an indicator; a wellbore tubular; and a collet coupled to the wellbore tubular. The collet comprises a collet protrusion disposed on one or more collet springs, and the collet protrusion has a position on the one or more collet springs that is configured to provide a first longitudinal force to the indicator in a first direction and a second longitudinal force to the indicator in a second direction. The first longitudinal force is different than the second longitudinal force.Type: ApplicationFiled: December 18, 2012Publication date: June 27, 2013Applicant: HALLIBURTON ENERGY SERVICES, INC.Inventor: HALLIBURTON ENERGY SERVICES, INC.

Patent number: 8408291Abstract: An engaging device includes a body selectively slidably engagable about a first tubular runnable within a second tubular. The body is runnable past at least one profile on the second tubular in a first direction during a first running and is prevented from running past the at least one profile on subsequent runs subsequent to running by the at least one profile in a second direction.Type: GrantFiled: March 23, 2010Date of Patent: April 2, 2013Assignee: Baker Hughes IncorporatedInventors: Bryan P. Pendleton, Thomas J. Zweifel

Publication number: 20130056223Abstract: The downhole torque limiter and method eliminate damage to downhole components by eliminating excessive torque transmission. The device comprises a housing, compression assemblies, and anti-rotation plates. Inner and outer assemblies of the device are permitted to slip with respect to each other after reaching a settable torque limit which is preferably below the maximum capacity of other downhole components. The device may be positioned in drill strings that comprise a downhole motor and/or drill bit as well as drill strings that do not comprise a downhole motor and/or drill bit. In drill strings comprising a downhole motor and/or drill bit, the device may be positioned below the downhole motor and above the drill bit, adjacent to and above the downhole motor, or above the downhole motor such that at least one drill string joint is positioned between the device and the downhole motor.Type: ApplicationFiled: August 29, 2012Publication date: March 7, 2013Inventor: Mark B. Nichols

Patent number: 8316954Abstract: An apparatus for separating a downhole tubular string into two parts. The apparatus includes a receptacle operably associated with a first part of the downhole tubular string and a mandrel operably associated with a second part of the downhole tubular string. First and second sleeves each having a profile are slidably positioned between the receptacle and the mandrel and are operable to be securably coupled to the mandrel in first and second positions relative to the mandrel. First and second rings are respectively positioned between the profiles of the first and second sleeves and the profiled surface of the receptacle. The first and second rings are operable to initially limit longitudinal movement of the receptacle relative to the mandrel, to prevent tubular string recoil during operation and to allow longitudinal movement of the receptacle relative to the mandrel after operation.Type: GrantFiled: December 22, 2009Date of Patent: November 27, 2012Assignee: Halliburton Energy Services, Inc.Inventor: Jody R. McGlothen

Patent number: 8281868Abstract: A well drilling tool has a tubular member connected into a casing string that serves as a drill string. A load shoulder is located within the bore of the tubular member. The load shoulder has a torque transferring portion that extends from a lower terminus to an upper terminus. The load shoulder has an axial force transferring portion that faces upward. A bottom hole assembly is lowered through the casing string and lands on the load shoulder. The bottom hole assembly has a mating profile to the load shoulder so that it will be supported by the load shoulder and will receive torque transferred from the load shoulder.Type: GrantFiled: February 5, 2010Date of Patent: October 9, 2012Assignee: Tesco CorporationInventor: Per G.

Publication number: 20120234559Abstract: The present invention provides a swivel sub for connection in a work string between a workstring and a downhole apparatus. The swivel sub includes a first substantially cylindrical body, including a sleeve portion having one or more teeth and a second substantially cylindrical body being partially located within the sleeve portion. The bodies are arranged to rotate relative to each other. The swivel sub also includes a sliding sleeve, having one or more teeth arranged mutually engage with the first teeth is axially moveable between disengaged and engaged positions, in one embodiment by a pressure differential being created in the sub. Further, the present invention provides methods for of running the tool, with particular application to setting and hanging of liners and screens.Type: ApplicationFiled: May 30, 2012Publication date: September 20, 2012Applicant: TERCEL OILFIELD PRODUCTS UK LIMITEDInventors: Paul HOWLETT, James BAIN
