  • Patent number: 10738573
    Abstract: 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.
