  • Patent number: 10280710
    Abstract: An auto-shut-in valve in a chemical injection valve is described for operation at a downhole location in a wellbore. The chemical injection valve includes a closure member that is maintained in an open position by fluid pressure in a chemical supply line such that diminishment of the fluid pressure in the chemical supply line automatically causes the closure member to move to a closed position. A first mating surface on the closure member is exposed to the fluid pressure in the chemical supply line when the closure member is in the open position, and defines a portion of an equivalent differential surface to which the fluid pressure is exposed to maintain the closure member in the open position. The first mating surface is isolated from the fluid pressure in the chemical supply line when the closure member is in the closed position.

  • Patent number: 8991506
    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: 8657010
    Abstract: A downhole flow device has a sliding and ported sleeves. A seal has a first component on the sliding sleeve and a second component on the ported sleeve. These components engage one another to seal flow through the ports in the ported sleeve. The components move apart to allow fluid flow through the ports. The components are protected from abrasion and flow by virtue of the seal's structure and how it is opened. The sliding sleeve moves hydraulically along an axis of the ported sleeve to reveal successive ports defined along the sleeve's axis. Operation of the device and the seal address both erosion and damage from differential pressure problems. Thus, the seal prevent damage when unloading a differential pressure across it, and abrasive flow does not have the opportunity to impinge on the sealing surfaces to cause erosion.

  • Publication number: 20140027126
    Abstract: The invention relates to a method and apparatus for of controlling the flow of a fluid. The fluid comprises a liquid phase and a dissolved gas phase. The fluid passes through a valve, the valve comprising a fluid inlet and a movable body located in a flow path through the valve, the movable body being arranged to move freely relative to the opening of the inlet to vary the flow-through area through which the fluid flows by means of the Bernoulli effect. The dimensions of the valve are such that flow of the fluid past the movable body causes a drop in pressure to below the bubble point of the gas phase in the liquid phase, thereby increasing flow of the fluid through the valve.
