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.

Abstract: A system for providing autonomous flow control of a fluid from a wellbore to an interior of a tubing string by using a variable flow resistance system. The system can include a body, with a chamber that can be configured to induce rotational flow in a fluid that flows through the chamber. The chamber can include an inlet for fluid entering the chamber and an outlet for fluid exiting the chamber. A cross-sectional area of the chamber can be reduced along a central axis of the chamber toward the outlet, with the cross-sectional area being perpendicular to a central axis. A well screen assembly may utilize one or more of the variable flow resistance systems to provide a determined flow resistance and/or flow rate of the fluid through the screen assembly.
