    Abstract: A valve assembly employed in subterranean wellbore systems includes a flapper member biased to a closed position by a pair of opposed wire springs. The wire springs provide sufficient torque to ensure robust operation of the flapper member and permit sufficient fluid flow through the limited space available in the valve assembly. A pair of symmetrical pair of wire springs may be robustly manufactured and individually installed without unnecessary accumulation of manufacturing tolerances or errors, thereby providing predictable torque levels to the flapper member. The wire springs may be secured in blind holes or other features defined in a circumferential surface of the flapper member to ensure the springs remain engaged with the flapper member throughout the operation of the valve assembly.

  • Patent number: 9546538
    Abstract: Fracking ports are initially obstructed with respective biased sleeves that have an associated release device responsive to a unique signal. The signal can be electronic or magnetic and delivered in a ball or dart that is dropped or pumped past a sensor associated with each release device. Each sensor is responsive to a unique signal. When the signal is received the release device allows the bias to shift the sleeve to open the fracture port and to let a flapper get biased onto an associated seat. The flapper and seat are preferably made from a material that eventually disappears leaving an unobstructed flow path in the passage. The method calls for repeating the process in an uphole direction until the entire zone is fractured. The flapper and seat can dissolve or otherwise disappear with well fluids, thermal effects, or added fluids to the well.

    Abstract: A wellbore servicing system comprising a pressure testing valve incorporated within a casing string and comprising a housing comprising one or more ports and an axial flowbore, a sliding sleeve, wherein the sliding sleeve is positioned within the housing and transitional from a first position to a second position through a sliding sleeve stroke, wherein, in the first position, the sliding sleeve blocks a route of fluid communication via the one or more ports and, in the second position the sliding sleeve does not block the route of fluid communication via the one or more ports, wherein the pressure testing valve is configured such that application of a predetermined pressure to the axial flowbore for a predetermined duration causes the sliding sleeve to transition from the first position to the second position, wherein the predetermined duration is at least about one minute.

  • Patent number: 9334700
    Abstract: A method and apparatus for conducting a reverse flow operation. The apparatus may be lowered into a wellbore on a work string, and includes an opening device, a closing device, and a locking device disposed in a housing. Pressurized fluid supplied through the work string may actuate the opening device to open fluid flow through ports in the housing. Pressurized fluid from the annulus may be supplied through the port in the reverse flow direction to actuate the locking device to enable fluid flow up through the work string back to the surface, and to release the closing device. Pressurized fluid supplied through the work string may actuate the closing device to close fluid flow through the ports in the housing.

  • Patent number: 9322251
    Abstract: A system and method for lifting reservoir fluids from reservoir to surface through a wellbore having a first tubing string extending through a packer in a wellbore casing. The system includes a bi-flow connector in the first tubing string, a second tubing string in the first tubing string below the bi-flow connector, and a third tubing string in the first tubing string above and connected with the bi-flow connector. A fluid displacement device in the third tubing string is configured to move reservoir fluids to the surface. The first tubing string allows pressured gas to move from the surface through the bi-flow connector to commingle with and lift reservoir fluids through annuli defined by the first and second tubing strings and defined by the casing and the first tubing string. The bi-flow connector is configured to allow simultaneous and non-contacting flow of the downward pressured gas and lifted reservoir fluid.

  • Patent number: 9309979
    Abstract: A self piloted check valve which utilizes closure of a piloting flapper valve to permit development of closure forces for a ball valve. The normally open ball valve has a central flow passage and simultaneously rotates and translates as it traverses between its fully open and fully closed positions. An opening bias system utilizes a combination of a first less stiff spring and a second stiffer spring. Reversible decoupling means disconnects and reconnects the second spring at a short travel distance from the normally open position of the ball, while the first spring always provides opening bias forces to the ball. The pressure induced force required to fully close the ball valve following decoupling of the second spring is more than the force required to overcome the combination of the first and second springs. Additionally, while the secondary spring is engaged, hydrodynamic damping of the ball opening movement is provided.

  • Patent number: 9291044
    Abstract: A method and apparatus for conducting a fracturing operation using a wellbore fracturing assembly. The assembly may be mechanically set and released from a wellbore using a coiled tubing string to conduct a fracturing operation adjacent an area of interest in a formation. The assembly may include an unloader for equalizing pressure between the assembly and the wellbore, a pair of spaced apart packers for straddling the area of interest, an injection port disposed between the packers for injecting fracturing fluid into the area of interest, and an anchor for securing the assembly in the wellbore. After conducting the fracturing operation, the assembly may be relocated to another area of interest to conduct another fracturing operation.

  • Patent number: 9291031
    Abstract: A down hole pressure isolation tool is placed in a pipe string and includes a pair of pressure discs having one side that is highly resistant to applied pressure and one side that ruptures when much lower pressures are applied to it. The weak sides of the pressure discs face each other. Rather than rupturing the discs by dropping a go-devil into the well, a first of the discs is ruptured or broken by the application of fluid pressure from the well head or surface. Formation pressure is then used, in different ways according to the different embodiments, to rupture the remaining disc.

  • Patent number: 9260956
    Abstract: A system is provided that is conducive to multi-stage stimulation in a near-continuous fashion. That is, unlike conventional stimulation systems, embodiments herein may operate without the requirement of traditional plug-setting, perforating and fracturing interventions on a zone by zone basis for a cemented completion. Rather, the system is outfitted with frac sleeves that may be shifted open to expose the bore to the formation while simultaneously achieving a seal through a ball drop technique. Once more, this manner of operation is rendered practical by the sleeve being of a passable configuration such that cementing of the casing is not impeded.
