  • 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.

  • 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.

    Abstract: A technique protects against premature actuation of a tool, such as a downhole well tool. The technique utilizes a degradable material positioned along a hydraulic actuation passage and/or between shiftable components of the tool. In some applications, the tool may comprise a primary flow passage and a hydraulic actuation passage separate from the primary flow passage. Hydraulic actuation of the tool or a corresponding tool is temporarily blocked by placing a degradable material in the hydraulic actuation passage. The degradable material dissolves or otherwise degrades over time via exposure to a degradation fluid. In other applications, the degradable material may be positioned to block movement of a shiftable component of the tool until the degradable material is sufficiently degraded to allow tool actuation.

  • Patent number: 8833448
    Abstract: A system for pressure testing the joints and walls of a production pipe includes a fluid system component that can be disposed at a first end of the production pipe so as to seal off the first end of the production pipe. The fluid system component prevents the flow of fluid out of the first end of the production pipe when the pressure within the production pipe is below a predetermined level. The fluid system component includes a sacrificial element that is adapted for preferential failure when the pressure within the production pipe exceeds the predetermined level. Upon failure of the sacrificial element, fluid is able to flow out of the production pipe through the fluid system component. The system may also include a test plug that prevents the activation of a drain component in the production pipe during the pressure testing of the production pipe.

  • Patent number: 8813848
    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, in some embodiments, 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. In another embodiment, a gas generating assembly located between the discs is actuated to produce enough pressure to rupture the discs.

  • Patent number: 8783351
    Abstract: A cementing tool (20) capable of being installed in a casing string (10) and configured to selectively permit the flow of cement through one or more ports (34) in the tool is provided. The ports (34) are normally sealed by rupture disc assemblies (36) comprising a rupture disc (62) that can be opened to permit flow of cement through the casing string central bore (32) and into the annulus (14) defined by the casing string (10) and the downhole formation (16). The cementing tool (20) is particularly useful during cementing operations in which the annulus (14) has become blocked by a collapsed portion of the formation by allowing the obstruction (104) to be bypassed and the flow of cement (100) into the annulus to be continued without substantial interruption. Tool (20) may also be used in multistage cementing operations.
