  • Publication number: 20140231095
    Abstract: An apparatus and method are described for autonomously controlling flow of fluid in a subterranean well, where fluid flow is controlled based on a fluid characteristic, such as viscosity or density, which changes over time. Fluid flows into a vortex assembly where a centrifugal force is imparted to the fluid. A less viscous fluid will have a relatively greater velocity and centrifugal force than a more viscous fluid. The fluid exits the vortex chamber by both a vortex outlet and a peripheral outlet. An autonomous valve element moves between an open position, in which fluid flows freely through the peripheral outlet, and a closed position, in which fluid flow through the peripheral outlet is restricted. The valve element is moved by the centrifugal force of the fluid, such that a fluid having a higher centrifugal force moves the valve element to the closed position, thereby reducing the total fluid flow through the vortex assembly.

  • Patent number: 8651188
    Abstract: A gas lift valve that has a longitudinally extending tubular body having an inlet and an outlet, a flow path extending between the inlet and the outlet, and a flow tube located inside the body. The flow tube is translatable in the axial direction between at least a first and a second position. A venturi orifice located inside the body along the flow path. A seal part is located proximate to the outlet of the body. A flapper is connected with the body by way of a hinge part and the flapper has at least a first open position and a second closed position. The closed position is where the flapper contacts the seal thereby closing the flowpath and the second closed position is where the flapper does not contact the seal and does not close the flowpath.

  • Publication number: 20140020904
    Abstract: A subsurface safety valve is operable to close a fluid flow path by virtue of an axially movable flow sleeve. The valve includes a recockable actuator and a latch mechanism so that the valve can be moved to a closed position without overcoming the pressure head and frictional forces currently encountered in conventional safety valves. The latch mechanism includes one or more micro pistons.

  • Publication number: 20130341050
    Abstract: A device having a hard seat support disposed with a hard seat to reduce or prevent buckling, bursting, and/or permanent deformation of the hard seat that compromises the seal across the hard sealing surface and flapper sealing surface interface. The hard seat support may be positioned along an inner periphery of the hard seat or in direct contact with an outer periphery of the hard seat.

  • Patent number: 8607811
    Abstract: A flapper valve preferably used in injection application in deep subterranean locations has an actuating sleeve with a seat to accept an object. A j-slot connects the actuation sleeve movement to the housing so that with an object on the seat and an applied pressure cycle the sleeve moves the flapper to the open position. The plug is dissolved and the injection begins. The plug can have an opening so as to allow continuous injection flow as the flapper is operated. Closing the flapper involves a second object on the same seat and a pressure cycle so that a spring can push the sleeve away from the flapper to allow a torsion spring on the flapper to close it.

  • Publication number: 20130319679
    Abstract: Methods and apparatus enable reliable and improved isolation between two portions of a bore extending through a casing string disposed in a borehole. A downhole deployment valve (DDV) may provide the isolation utilizing a valve member, such as a flapper, that is disposed in a housing of the DDV and is designed to close against a seat within the housing. The DDV includes an operating mechanism for opening/closing the DDV. In use, pressure in one portion of a well that is in fluid communication with a well surface may be bled off and open at well surface while maintaining pressure in another portion of the casing string beyond the DDV.

  • Publication number: 20130292133
    Abstract: A valve assembly (2) which is configured to be coupled to a tubing string comprises a housing (8) defining a housing flow path (9) for communicating with the tubing string, and a barrier member (14) located in the housing (8) and configurable between a normally-closed position in which the barrier member (14) restricts access through the housing flow path (9), and an open position in which access is permitted through the housing flow path (9). The valve assembly (2) also comprises a bypass arrangement reconfigurable between an open state in which the bypass arrangement defines a bypass flow path that communicates with the housing flow path (9) on opposite sides of the barrier member (14) to permit fluid to bypass the barrier member and thereby fill the tubing string, and a closed state in which fluid is prevented from bypassing the barrier member to thereby permit pressurization of the tubing string.

  • Patent number: 8573304
    Abstract: A safety valve for use in a subterranean well can include a housing assembly having a flow passage extending longitudinally through the housing assembly. An outer diameter of the housing assembly is eccentric relative to the flow passage. A well tool can include a magnetic coupling between magnet devices. One magnet device includes a series of magnets which are unequally spaced circumferentially about the other magnet device. Another safety valve can include a longitudinally extending flow passage, a closure device which selectively permits and prevents flow through the flow passage, and an outer diameter which is eccentric relative to the flow passage.
