  • Patent number: 11280151
    Abstract: An apparatus, system, and method are provided for injecting carrier sleeves into a wellbore. The injection system is capable of individually indexing a selected sleeve from a sleeve magazine into an injector bore and axially aligning the sleeve with the bore with a retaining device. The retaining device prevents a subsequent sleeve from being indexed into the bore from the magazine. The selected sleeve can be restricted from free fall using a staging mechanism, which can subsequently be opened to permit the selected sleeve to fall into a staging bore. The staging bore is then fluidly isolated from the injector bore and the wellbore, pressure in the staging bore is equalized with the wellbore, and then opened to the wellbore for injecting the sleeve into the wellbore. The sleeve can be axially aligned and radially centered with the injector bore using a tapered portion in the bore or the staging mechanism.

  • Patent number: 11257597
    Abstract: Packaging structures and systems are used for handling components for use in a nuclear reactor. The packaging protects the component during transport and handling and then dissolves in liquid in the nuclear reactor or fuel pool. The packaging need not be removed and may block flow paths or otherwise interfere with operability were it not for its dissolution. The packaging may include shock absorbers in a fuel assembly or a seal on a water rod in the assembly. Mechanical, frictional, or chemical retaining materials may be used to secure the packaging and may also dissolve in the liquid. For a light water reactor, polymers, protein gels, and plastics can all be used where they will dissolve in the water and are otherwise compatible with reactor chemistry and neutronics. Materials with higher temperatures for solubility may be used because they will dissolve when reactor operations commence.

  • Patent number: 8893799
    Abstract: A safety valve for an effluent-production installation, the safety valve comprising a longitudinal shell in which there extends a production tube defining an inside volume for effluent flow. The tube is movable in translation inside the shell in an axial direction between an advanced position in which effluent flow is authorized from the bottom of the installation towards the surface, and a retracted position in which effluent flow is prevented. The valve includes a connection duct between a feed line for feeding at least one additive from the surface and an injection line for injecting the additive downhole, a safety plug being provided in the connection duct in order to close or open the duct depending on whether the production tube is in its retracted position or its advanced position.

  • Patent number: 8857511
    Abstract: Apparatus and method are provided to restore contaminated groundwater based on in-situ periodic pumping and recharging. The apparatus includes a contaminated groundwater suction system, an in-situ restoration system, and a reinjection system. The suction system includes a suction well and a suction pipeline. The suction system is connected with the in-situ restoration system. The in-situ restoration system is connected with the reinjection system. The reinjection system includes a reinjection pipeline and a reinjection well. Prior to the in-situ restoration, a pumping test for suction well and an injection test for reinjection well are conducted. Through reinjecting the processed contaminated groundwater, this approach is capable of diluting contaminated water layer, reducing the pollutant concentration in the target aquifer, providing convenience for the subsequent processing, and cutting the cost.

  • Publication number: 20140262260
    Abstract: A sand control device is used for restricting the flow of particles from a subsurface formation into a tubular body within a wellbore during production operations. The sand control device is divided into compartments along its length that provide redundancy for particle filtration. Each compartment first comprises a base pipe. The base pipe defines an elongated tubular body having a permeable section and an impermeable section within each compartment. Each compartment also comprises a first filtering conduit and a second filtering conduit. The filtering conduits comprise filtering media and generally circumscribe the base pipe. The filtering conduits are arranged so that the first filtering conduit is adjacent to the non-permeable section of the base pipe, while the second filtering conduit is adjacent to the permeable section of the base pipe.
