  • Patent number: 10459461
    Abstract: An apparatus to distribute pressurized fluid from one or more sources to multiple wellbores. The apparatus includes a manifold having at least two inlets and at least two outlets. Pressurized fluid is brought into the manifold from opposing directions so that the fluid from one inlet will impinge upon the fluid from the other inlet thereby deenergizing the fluid. Additionally, the manifold is configured such that the cross-sectional area of the inlets is less than the cross-sectional area of the manifold thereby decreasing velocity minimizing the kinetic energy available to erode or otherwise damage equipment, while providing a pressure decrease as the fluid enters the manifold. The outlets are configured such that the cross-sectional area of the outlets providing fluid to a single wellbore is greater than or equal to the cross-sectional area of the inlets such that no pressure increase occurs within the manifold or the outlets as the fluid exits the manifold.

  • Patent number: 10450833
    Abstract: A self-regulating flow control device for controlling the flow of injected fluid into a subsea well or flowline via a tree, manifold, or other access point on the subsea infrastructure by responding to the injection pressure being applied to prevent the conduit from collapsing. An embodiment of the self-regulating flow control device includes a housing having a first and second through bore, a piston moveable in the through bore, and a biasing member. When in an unactuated position, the biasing member biases the piston isolating the first through bore from the second through bore, and when in an actuated position, a pressure overcomes the biasing member to move the piston and expose the first through bore to the second through bore. The self-regulating control flow device prevents a vacuum from being drawn into the conduit system below during sudden decreases in uphole pressure by blocking or closing flow paths in the housing.

  • Patent number: 10442675
    Abstract: A vent system for a fuel storage tank and a pressure vacuum valve (PVV) module for use with such a vent system are disclosed. The vent system defines a vent path from the fuel storage tank to atmosphere. An elongate vent pipe extends vertically to a rain cap located at the upper end of the vent pipe. A pressure vacuum valve (PVV) is located in the vent path between the lower end of the vent pipe and the tank. The pressure vacuum valve maintains the vent path in a closed condition unless the pressure in the tank is above or below a predetermined pressure. By separating the PVV from the rain cap and placing it between the lower end of the vent pipe and the tank, it is possible to site the PVV at an accessible level for maintenance.

  • Patent number: 10436331
    Abstract: A seal with a wedging element for adjustably compressing the seal. The seal abuts a surface, such as a gate of a gate valve, to seal against the surface with a sealing force that prevents fluid flow therebetween. The sealing force of the seal may be increasing or decreasing compression by adjusting the wedging mechanism. For example, as the seal wears away due to friction between the seal and a sliding gate, the compression may be increased in the wedging mechanism to increase the sealing force to a low threshold.
