A Flow Control Device And Method
Patent No. EP4471530 (titled "A Flow Control Device And Method") was filed by Inflowcontrol on Mar 11, 2019. The application was issued on Nov 5, 2025.
Patent Summary
A fluid flow control device establishes controllable communication between an external reservoir and a production string base pipe. It comprises a housing containing a primary flow path with an axial inlet and an outlet to the base pipe. A secondary flow path, where a major portion extends outside the housing, includes a first fluid flow restrictor, a second fluid flow restrictor, and an intermediate chamber. The first restrictor generates a pressure drop from $p_1$ to $p_2$, and the second from $p_2$ to $p_3$. A movable valve element within the housing closes the primary flow path when the pressure force within the chamber exceeds a threshold, enabling autonomous, reversible control of fluid phases based on fluid properties.
