Abstract: A technique facilitates controlling flow in a wellbore. One or more flow control valve assemblies may be designed for coupling with downhole well equipment. Each flow control valve assembly comprises a flow control valve which cooperates with a control module. The control module comprises a plurality of electrically controlled valves arranged to control flow of actuating fluid to the flow control valve. Each flow control valve assembly also comprises a hydraulic override system to enable hydraulic actuation of the flow control valve to a predetermined position when, for example, no electrical power is available for the electrically controlled valves of the control module.

Abstract: A technique is provided for utilizing a hydraulic fluid metering control module in cooperation with a downhole component. The downhole component is shifted via hydraulic fluid delivered through first and/or second control lines to an actuator of the downhole component. The hydraulic fluid metering control module works in cooperation with the actuator and the control lines to enable shifting of the actuator according to a controlled, incremental process.

Abstract: Embodiments of the present invention relate to a volumetric compensating annular bellows used to compensate two fluid volumes by an annular displacement. This is achieved using a bellows welded on to a tube with a varying shape radius. A bellows is arranged within the annulus and is deformable in an annular direction in response to fluid volume expansion. The bellows can be used in several oilfield applications for fluid compensation.
