  • Patent number: 9909388
    Abstract: A valve can include a closure device which selectively permits and prevents fluid communication between an interior and an exterior of the valve, an incremental displacement device which incrementally displaces the closure device in response to pressure differentials between the interior and the exterior of the valve, and an accelerator device which accelerates displacement of the closure device in response to a predetermined pattern of the pressure differentials. A method of operating a valve in a well can include applying a predetermined pattern of pressure differentials between an interior and an exterior of a tubular string in which the valve is connected, thereby incrementally displacing a closure device of the valve, and accelerating displacement of the closure device in response to the predetermined pattern of pressure differentials, thereby displacing the closure device to a selected one of an open and a closed position.

  • Patent number: 8967268
    Abstract: A circulation sub is provided that has a ball seat and a circulation port that is closed when a ball is landed on the seat. An axial passage directs the pressure surge created with the landing of the ball on the seat to the port with the actuation piston for the tool. The surge in pressure operates the actuation piston to set the tool, which is preferably a packer. Raising the circulation rate through a constriction in a circulation sub breaks a shear device and allows the restriction to shift to cover a circulation port. The pressure surge that ensues continues through the restriction to the actuating piston for the tool to set the tool.

  • Patent number: 8967280
    Abstract: A lock assembly for a mechanically set packer for deep deployments is described. The lock housing wall has at least one bore for a rod piston that is selectively actuated when wellbore hydrostatic is allowed to reach on side of the piston. Movement of the piston, after breaking a shear pin, allows a c-ring to spring outwardly and out of a locking groove in the mandrel so that the mandrel can be string manipulated with respect to the housing to set the packer. Once unlocked the lock assembly remains defeated. The piston can be optionally exposed to hydrostatic and will unlock at a given depth without manipulation of the wellbore annulus pressure. Other mechanisms to admit wellbore hydrostatic to move the piston or to move the piston in general by other techniques are described.

  • Publication number: 20140352974
    Abstract: Fluid actuated chokes include an expandable material that expands due to an undesired fluid coming in contact with the choke. The choke includes one or more passageways through which desired fluids from a well flow unimpeded. The choke is disposed in a downhole tool as part of a downhole completion. When one or more undesired fluids enters a production stream flowing through the downhole completion and, thus, the downhole tool, and contacts the choke, the expandable material expands causing fluid flow through the passageway(s) to be restricted and, in some cases, completely closed off. Thus, the choke automatically detects and reacts, i.e., restricts fluid flow through the choke, when contacted by the undesired fluid(s).

The time delay is a fluid system that drives fluid through a narrow restriction. The restriction is variable to allow unloading of the resistance from the fluid system while the dogs are still adequately supported. As a result the dogs are released from the profile without regional overstressing. A lock can prevent the tool from resetting to limit its use to locating at a single location. The lock holds the hydraulic system in a defeated position so that even if the dogs engage another profile when locked they will immediately exit that profile.

  • Patent number: 7637324
    Abstract: A valve for a line going to a subsurface safety valve can be blocked off with a valve that is initially held in a closed position. An upper spring pushes collets against a shoulder to keep a seal on a support assembly for the collets within an initial bore in a sealing relation. Application of pressure to the line urges the support assembly to move with respect to the collets and causes the collets to become unsupported. This initial movement of the support assembly is against a second spring that is weaker than the upper spring. The upper spring forces the collapsed collets into a smaller bore while the support assembly is retained against reverse movement at the urging of the second spring by a ratchet assembly. The seal is shifted into a bigger bore to allow flow through the valve and into or beyond the subsurface safety valve.

  • Publication number: 20090071654
    Abstract: A flapper type downhole valve is opened by flow against the flapper. The flapper and the housing contain magnets that hold the flapper open after it has been opened by flow to keep the flapper from chattering from the flow going past it. The strength of the force is not sufficient to hold the flapper open against a torsion spring on a pivot pin, when there is no flow through the valve. The valve can still be held in the locked open position with no flow through the housing by pressurizing the surrounding annulus to position another magnet to increase the holding force to a level greater than the force of the torsion spring. The additional magnet is spring biased so that upon removal of annulus pressure it shifts to allow the flapper to close. Alternative designs with and without a flow tube are possible. Fixed or movable restrictions can be associated with the flow tube to create a force to shift it to open a flapper with flow into the well.

  • Patent number: 7503390
    Abstract: A locking device prevents stressing of other components used to hold tool portions against relative movement until a desired location is reached. A locking dog holds a first component, such as a sliding sleeve to a second component, such as a mandrel until pressure can move a piston and remove support for the dog. The same pressure that removes support for the dog to unlock the lock also forces a retainer, such as a shear pin that holds a sleeve to break to allow the sleeve to shift. The locking dog keeps stress off the shear pin when the locking dog is supported in the run in configuration. An alternative design uses a grease filled cavity to dampen shocks that could load a shear pin to the point of failure.
