A fluid flow control device for establishing a controllable fluid communication between an external fluid reservoir and a base pipe constituting part of a production string, as well as a production string and a method using such a fluid flow control device. The fluid flow control device comprises a primary flow path arranged inside a fluid control device housing, a secondary flow path and a movable valve element arranged at and/or within the primary flow path. The inlet of the secondary flow path is arranged separate from the inlet of the primary flow path.

Flow control device and method

The present invention relates to a system and a pressure activated valve for preventing fluid from passing through an ICD during installation and commissioning of a production string in a well bore. Further the invention relates to a method for operating the pressure activated valve. The pressure activated valve can be arranged outside the production string being configured to hinder fluid from entering the ICD from a reservoir when the pressure activated valve is closed and to allow fluid from entering from the reservoir when pressure activated valve is open.

Pressure actuated valve for use during installation and commission of a production string

A fluid flow control system serving as an inflow port from a fluid reservoir (R) to the interior of a production pipe (S) is in the form of a housing (). The housing has a primary flow path () and a secondary flow path (). The secondary flow path is in fluid communication with a chamber (B) in which is arranged an actuator () for a valve device (), the valve device arranged to open and close the primary flow path. At least one flow restrictor () is arranged in the secondary flow path, the flow restrictor arranged to provide a pressure to chamber (B) sufficient to actuate the valve to an open position when the fluid flowing through the secondary flow path is oil, and a pressure sufficient to actuate the valve to a closed position when the fluid has a viscosity and/or density less than oil.

Flow control device

A fluid flow control device includes a housing having a fluid inlet () and at least one fluid outlet (). A first fluid flow restrictor () serves as an inflow port to a chamber (B) in the housing, and a second fluid flow restrictor () serves as an outflow port from the chamber (B). The first fluid flow restrictor and the second fluid flow restrictor are configured to generate different fluid flow characteristics; and the chamber (B) includes an actuating device (-) that is responsive to fluid pressure changes (&#x394;P) in the chamber. The first fluid flow restrictor () and the second fluid flow restrictor () are configured to impose respective different fluid flow characteristics based on different fluid properties.
