  • Patent number: 10519744
    Abstract: An isolation valve system, method, and apparatus are provided that can isolate a wellbore and prevent fluids from exiting the well and prevent seawater from entering the well. The system can be a two-part design in some embodiments where a shear sub is selectively interconnected to a body via shearing screws. A sufficient force on the shear sub destroys the shearing screws and the shear sub is removed from the body. This movement rotates an actuator on the body, which in turn rotates a valve in the body to provide the isolating function during routine operation of a wellbore or during an emergency.

  • Patent number: 10472929
    Abstract: A safety valve features a flow tube operated flapper for the normal open and closed positions that can be obtained with one or two control lines to a principal operating piston. Pressure applied to the piston moves the flow tube to rotate the flapper open behind the flow tube. Release of pressure to the principal piston allows a closure spring to return the flow tube up to let the flapper close. A secondary piston can drive the flow tube with applied pressure through a control line. Cycling the applied pressure in combination with an indexing mechanism allows the flapper to be locked open and then released to normal operation. The pistons act as backup for each other as they both drive the flow tube. The flow tube has a clearance fit to the body in the locked open position to exclude debris from the flapper.

The semi-autonomous insert valve includes a body, a closure mechanism coupled to the body, an autonomous actuation mechanism coupled to the body, and a control system disposed in the body. The body engages an inner wall of a subsurface safety valve and causes a subsurface safety valve closure mechanism to open, allowing fluid to flow toward the surface of the wellbore. The closure mechanism selectively allows fluid to flow toward the surface of the wellbore. The autonomous actuation mechanism actuates the closure mechanism independently from a subsurface safety valve actuation mechanism that actuates the subsurface safety valve closure mechanism. The control sub-system includes one or more transceiving devices that can wirelessly communicate signals. The control sub-system closes the closure mechanism in response to losing signal communication between the transceiving devices and a signal source.

  • Patent number: 9174553
    Abstract: A seat, in particular motor vehicle seat, with a seat part and a backrest pivotally mounted relative to the seat part, which includes a backrest frame with two mutually opposite side bars, is provided. The two side bars are connected with each other via a transverse shaft which is rotatably mounted on the seat part in the region of a side bar. At least one fitting arrangement with a fitting part fixed at the backrest frame is provided, in order to arrest the pivotally mounted backrest relative to the seat part. The fitting part fixed at the backrest frame is welded to one of the side bars and the transverse shaft is welded to this fitting part. An end of the transverse shaft extends through one of the two side bars and this end is rotatably mounted in a seat side part of the seat part, so that the transverse shaft defines a pivot axis about which the backrest is pivotable relative to the seat part.

  • Patent number: 9163489
    Abstract: A method is described of injecting CO2 into an aquifer or a depleted hydrocarbon reservoir (211) via at least one injection well (202) that penetrates said aquifer or reservoir, wherein the injection well is provided with an injection tubing (203) that is in sealing engagement with the injection well. The injection tubing terminates at or immediately above the interval of the aquifer or the reservoir into which the CO2 is to be injected and the injection tubing is provided with a fluid injection control valve (208) at or near the bottom thereof which is closed or closes when the pressure above the valve is less than a pre-set pressure value and opens or reopens when the pressure above the valve is at or greater than said pre-set pressure value, the pre-set pressure value being selected such that the CO2 in the injection tubing is maintained in a liquid or supercritical state.

  • Patent number: 9145748
    Abstract: Apparatus for diverting fluid flow out of a working string, having a primary sub housing defining an axial bore and one or more primary sub housing circulation ports; a valve within the housing and defining one or more valve circulation ports. The valve ports are in fluid communication with the housing ports when the valve is in an open circulation position. One or more fluid-impinged surfaces are included and disposed within the primary sub housing and in operative connection with the valve. Fluid flowing through the primary sub housing impinges upon the fluid-impinged surfaces and, at a sufficient flow rate, causes the valve to move so as to actuate the valve in opposition to a biasing force operating on the valve and into open circulation position to cause flow of fluid out of the valve and primary sub housing through the aligned valve and primary housing ports.

    Abstract: Apparatus (10) for restricting a flow of fluid through a bore (14) comprises a bore sealing member (12a) and an actuation assembly for moving the bore sealing member (12a) between first and second configurations. The actuation assembly is configured to isolate first and second end portions (46, 48) of the activation member (12a) from a bore fluid (50). The apparatus (10) provides for moving the bore sealing member (12a) between the first and second configurations without a bore fluid (50) pressure acting on an end portion (46, 48) of the activation member (12a).

  • Patent number: 9127528
    Abstract: A technique facilitates control over a multi-position well tool. A hydraulic control module may be engaged with a multi-position well tool for controlling actuation of the multi-position well tool through a plurality of actuation positions. The multi-position well tool is moved through the plurality of actuation positions by applying pressurized fluid through a first control line. A metering piston is uniquely arranged within the hydraulic control module to control actuation of the multi-position well tool from an initial actuation position through a plurality of incremental actuation positions. Additionally, a single pressurization of actuation fluid delivered through a second control line may be used to return the multi-position well tool back to the initial actuation position from any incremental position.

  • Publication number: 20150129196
    Abstract: Two control systems are provided to run in parallel between a surface location and the final controlled element, in this case a subsurface safety valve. The primary control circuit is controlling until a predetermined signal is given to the secondary control line which has the effect of actuating the valve a single time against the force of a bias or a shear pin that breaks. The movement of a shuttle in the housing due to the predetermined signal being provided in the secondary line puts the secondary control system in the position of running the tool. The primary system is valved off and cannot return into service. There are just two lines into and out of the housing to make the valve operate at the desired location. A test port is provided for surface testing.
