  • Patent number: 8550177
    Abstract: Packer assemblies capable of providing desired load-bearing performance and of being retrieved from a bore in a subterranean formation are described. A packer assembly can include a wedge that can respond to a force in a downhole direction by un-supporting the slip. The unsupported slip is configured to disengage from a casing string, allowing the packer assembly to be removed from the bore. The wedge can include a collet to allow the wedge to separate from the slip to prevent slip re-setting.

  • Publication number: 20120168148
    Abstract: A collet assembly has a housing and the collets disposed on flexible fingers connected to the housing at their opposed ends. A surrounding landing sleeve stops the assembly so that collets are aligned with a recess in a landing collar that is part of a surrounding tubing string. Once set the landing sleeve transmits compressive loads so that compressive stress essentially bypasses the finger structure supporting the collets. The fingers are initially tapered toward a longitudinal axis so that when internally supported they assume an aligned orientation to the housing axis to allow greater tensile loading and to provide a retraction force when the housing is to be removed after the collet support is removed.

  • Patent number: 8181701
    Abstract: A downhole tool 100 includes closure seats 116, 176 for seating with a closure, such as a ball. Shear pins or other connectors temporarily limit axial movement of each closure seat which is initially housed within a restricted diameter portion of the central throughbore in the tool body. A piston axially moves in response to fluid pressure to pressurize fluid in a chamber and controllably release fluid through one or more restrictions. The closure seat may be lowered to engage a stop 108, 159, such that the seat may move axially to an enlarged diameter bore portion of the tool, thereby allowing radial expansion of a closure seat to release the ball.

  • Patent number: 5992801
    Abstract: A primary pipe gripping mechanism and a backup, secondary pipe gripping mechanism are carried in a single tapered slip bowl. The primary gripping mechanism employs smooth surface pipe dies that set against and grip and hold the pipe without damaging the pipe surface. After the primary mechanism is set, toothed dies in the secondary gripping are automatically engaged with the pipe with only a minimal pipe gripping force. Accidental slippage of the pipe through the smooth dies sets the toothed dies down against a wedging surface to grip and hold the pipe to stop its downward movement. A resilient biasing device is used to urge the toothed dies away from the pipe before the smooth dies are set. Movement of the pipe relative to the already set, smooth dies automatically causes the toothed dies to set and grip the pipe to thereby limit the incidence of pipe damage to those situations in which pipe slippage occurs through the primary gripping mechanism.

  • Patent number: 5732909
    Abstract: A slip die with a substantially smooth pipe contact surface is employed in a conventional slip assembly as a primary mechanism for gripping pipe. A second conventional slip assembly with conventional dies having penetrating die teeth on their contact surfaces is employed as a secondary gripping mechanism to automatically grip the pipe in the event the primary mechanism loses its grip. The smooth slip elements are constructed of a malleable material which tends to conform to surface irregularities on the outer surface of the pipe to increase the gripping force on the pipe. In the method, the pipe is initially gripped by the primary slip mechanism before the secondary mechanism is actuated to contact the pipe. The slips are set by downward pipe forces acting on the dies so that the die teeth of the secondary mechanism do not grip the pipe unless the primary slip mechanism fails.

    Abstract: A hanger for hanging a string of conduit within a wellhead has a metal-to-metal seal. The hanger has a body that locates within the wellhead and provides an annular clearance between the body and the wellhead. A locking device fits within this clearance to lock the hanger against axial movement. The metal-to-metal seal is an annular ring with inner and outer cylindrical sidewalls. The seal has a cavity into which a wedge ring is driven to urge the sidewalls apart to embed within the hanger body and wellhead bore. The locking device has reacting wedges that urge a split ring outward into engagement with the wellhead. A retaining mechanism is then moved downwardly with the seal to retain the split ring in locking engagement.

  • Patent number: 4122899
    Abstract: A cased borehole has a tubing string run downhole thereof. A packer affixed to the tubing is set with the tubing string terminating in proximity of a hydrocarbon producing formation to be completed. A wireline operated perforating gun is suspended from a mass by means of a lost motion coupling and the mass is suspended from a wireline. The entire apparatus is run downhole and positioned adjacent to the hydrocarbon containing formation. The gun is detonated; whereupon formation fluid enters the casing and tends to thrust the gun uphole respective to the mass and to the wireline. The relative motion between the gun and mass is advantageously used to set a tool hold down apparatus which arrests uphole thrust of the gun. The gun can be subsequently retrieved by lifting the mass with the wireline, thereby releasing the tool hold down apparatus and enabling wireline retrieval of the entire apparatus suspended from the wireline.
