  • Publication number: 20130186649
    Abstract: A tool setting arrangement includes a mandrel, and a tool positionable at the mandrel. The tool includes, a cone, and at least one slip in operable communication with the cone configured to radially expand to set the tool when the slip is moved relative to the cone with at least a setting load. The at least one slip has a portion configured to engage with a feature of the mandrel such that movement of the mandrel relative to the cone causes the at least one slip to move relative to the cone, at least one of the portion and the feature is configured to release at a release load to disengage the mandrel from the tool. The release load is selected to be greater than the setting load.

  • Publication number: 20130186648
    Abstract: A tubular anchoring system includes a frustoconical member having a first frustoconical portion and a second frustoconical portion. The first frustoconical portion is tapered in a direction opposing a direction of taper of the second frustoconical portion and slips in operable communication with the first frustoconical portion are radially expandable in response to longitudinal movement of the first frustoconical portion relative to the slips. A seal in operable communication with the second frustoconical portion is radially expandable in response to longitudinal movement of the second frustoconical portion relative to the seal, and a seat having a surface configured to be sealingly engagable with a plug runnable thereagainst.

  • Publication number: 20130186616
    Abstract: A tubular anchoring system includes a first frustoconical member. Slips in operable communication with the first frustoconical member are radially expandable into an anchoring engagement with a structure in response to longitudinal movement relative to a frustoconical surface of the first frustoconical member. A collar in operable communication with the first frustoconical member is radially expandable into sealing engagement with the structure in response to longitudinal movement relative to a second frustoconical member. A seat in operable communication with the first frustoconical member having a surface configured to be sealingly engagable with a plug runnable thereagainst, is configured and positioned relative to the collar to aid the seat in maintaining a radially expanded configuration against a pressure differential formed across the seat when plugged.

  • Publication number: 20130186647
    Abstract: A tubular anchoring system includes a frustoconical member and a sleeve with at least one first surface that is radially alterable in response to longitudinal movement of the frustoconical member relative to the sleeve. The at least one first surface is engagable with a wall of a structure positioned radially thereof to maintain position of at least the sleeve relative to the structure when engaged therewith. A seal with at least one second surface is radially alterable in response to longitudinal movement of the frustoconical member relative to the seal, and a seat is in operable communication with the frustoconical member having a land which is sealingly engagable with a removable plug runnable thereagainst. The land is longitudinally displaced relative to the sleeve in an upstream direction defined by direction of flow that urges the plug thereagainst.

  • Publication number: 20130025877
    Abstract: Sliding sleeve valves that include a housing with an axial flowbore defined along its length and at least one lateral fluid port disposed through the housing. One or more sliding sleeve members are disposed within the flowbore and carry first and second ball seats. Landing a first ball onto the first ball seat will move the valve from a first position wherein lateral flow is blocked to a second position wherein lateral flow is permitted. Landing a second ball onto the second ball seat will move the valve to a third position wherein lateral flow is again blocked and axial flow is permitted.

  • Patent number: 6851472
    Abstract: A tubular scraper which can be assembled so that the blades will be either rotating or non-rotating, as desired. If the tubular scraper is assembled in the non-rotating configuration, and the blades becomes stuck in the casing, the drill string can be pulled upward to engage a clutch. Once the clutch is engaged, the scraper is converted to a rotating scraper, so that the drill string can be rotated to assist in dislodging the stuck scraper blades.
