Patent Summary

A fluid flow control device for subsea production strings that autonomously regulates fluid flow based on changes in fluid properties, such as viscosity, density, or composition. The device comprises a primary flow path and a secondary flow path with a flow restrictor that creates a pressure differential between the two paths. When the fluid properties change, the pressure differential changes, causing the flow restrictor to open or close the secondary flow path, thereby controlling fluid flow into the production string. The device is compact, reversible, and operates without the need for external power or control signals.
