Isolation plugs may be installed in a wellbore flow control device to temporarily close a flow path therethrough. The isolation plugs may be installed in threaded openings often provided to for access to nozzles or other flow restrictors in the flow control devices. The isolation plugs may initially be locked in a closed configuration while being run in hole and may be unlocked in response to the application of a predetermined activation pressure. Once unlocked, the isolation plug may not immediately move to an open configuration but may continue holding pressure to permit circulation and washdown operations to be conducted. The activation pressure may be reduced to a second predetermined threshold to lock the isolation plug in the open configuration wherein flow is permitted through the flow control device.

Mechanical isolation plugs for inflow control devices

A wellbore downhole tool, comprising: a nozzle assembly, the nozzle assembly includes a nozzle including: a cylindrically-shaped tube with a substantially uniform outer diameter across substantially an entire height of the nozzle, at least one retaining body opening located in an outer wall of the nozzle; a holding body including: a conduit, the conduit sized to fit the nozzle there-through, an alignment opening extending from an outer surface of the holding body to the conduit; and a retaining body sized to fit within the alignment opening of the holding body and to contact the retaining body opening of the nozzle when the nozzle is inserted in the conduit such that the cylindrically-shaped tube of the nozzle cannot rotate or move further in or out of the conduit. A method of assembling the wellbore downhole tool is also described.

Nozzle assembly for shunt tube systems

Fluid flow control systems are configured to resist erosion-corrosion and minimize wall shear stress during injection or production. A fluid flow control system includes a base pipe with an internal passageway. A housing is positioned around the base pipe to define a fluid flow path between the filter component and the internal passageway. A flow control component is positioned within the fluid flow path in order to control fluid flow. A flow-induced erosion resistance component, which may take a variety of forms, is positioned within the fluid flow path to reduce and/or eliminate wall shear stress along the base pipe. As a result, erosion-corrosion of the bases pipe is reduced and/or eliminated altogether.

A well screen assembly includes a tubing including a center bore and at least one aperture through the tubing between an outer radial surface of the tubing and an inner radial surface of the tubing; a filtration screen positioned around the tubing; a housing positioned around the tubing and including a fluid chamber in fluid communication with an outlet of the filtration screen; and a flow control device positioned in fluid communication with the outlet of the filtration screen and the at least one aperture to reduce a wall shear stress on at least one of the tubing or the at least one aperture.

Flow conditioning flow control device

Disclosed are flow distribution assemblies for distributing fluid flow through well screens. One flow distribution assembly includes a bulkhead arranged about a base pipe having one or more flow ports and defining flow conduits in fluid communication with the flow ports, a sand screen arranged about the base pipe and extending axially from the bulkhead, a flow annulus defined between the sand screen and the base pipe, and flow tubes fluidly coupled to the flow conduits and extending axially from the bulkhead within the flow annulus, the flow tubes being configured to place an interior of the base pipe in fluid communication with the flow annulus via the flow ports, wherein the flow tubes distribute a fluid through the at least one sand screen at a plurality of axial locations within the flow annulus.
