Abstract

Official abstract text for this publication.

A technique facilitates flow control downhole via at least one flow control valve. According to an example, a flow control valve has an internal piston. Additionally, an electrically powered actuator is mounted externally to the flow control valve and connected to the internal piston via a linkage. The electrically powered actuator is responsive to electrical inputs to shift the internal piston to desired flow positions of the flow control valve.

First claim

Opening claim text (preview).

The invention claimed is: 1. A system for use in a well, comprising: a well tubing including an internal cross-sectional area; a flow control valve mounted along the well tubing, the flow control valve comprising a housing and an internal piston moveably disposed within the housing, wherein a flow area of the flow control valve is equivalent to the internal cross-sectional area of the well tubing; and an electrically powered actuator mounted externally to the flow control valve and connected to the internal piston via a linkage, the electrically powered actuator responding to electrical inputs to shift the internal piston to flow positions. 2. The system as recited in claim 1 , wherein the electrically powered actuator is held in place along an outer surface of the housing of the flow control valve with one or more clamps or protectors. 3. The system as recited in claim 1 , wherein the electrically powered actuator is disposed in a groove formed in an outer surface of the housing of the flow control valve. 4. The system as recited in claim 1 , wherein an outer surface of the housing comprises one or more grooves formed therein. 5. The system as recited in claim 4 , wherein the one or more grooves comprises a first groove housing the electrically powered actuator and a second groove housing electronics or one or more sensors. 6. The system as recited in claim 1 , wherein the electrically powered actuator comprises an electro-mechanical actuator (EMA). 7. The system as recited in claim 1 , wherein the electrically powered actuator comprises an electro-hydraulic actuator (EHA). 8. The system as recited in claim 7 , further comprising a manifold and a pump system comprising a motor and a pump, the manifold comprising hydraulic circuitry linking the pump system to the electrically powered actuator, and the pump system configured to pump hydraulic control fluid from a reservoir through the manifold to the electrically powered actuator. 9. The system as recited in claim 8 , the manifold comprising at least one solenoid operated valve (SOV). 10. The system as recited in claim 7 , wherein mechanical intervention for mechanically shifting the flow control valve is configured to be performed while the electrically powered actuator is connected to the internal piston. 11. The system as recited in claim 1 , wherein the linkage is configured to be disconnected to enable mechanical intervention for mechanically shifting the flow control valve. 12. A flow control valve comprising: a housing; a flow area, the flow area being equivalent to an internal cross-sectional area of a well tubing in which the flow control valve is disposed; a piston movably disposed within the housing to adjust flow through the flow control valve; at least one groove formed in an outer surface of the housing, wherein the at least one groove comprises a first groove housing an electrically powered actuator and a second groove housing electronics; and a linkage coupling the electrically powered actuator to the piston such that movement of the electrically powered actuator causes movement of the piston. 13. The flow control valve of claim 12 , wherein the electrically powered actuator is held in place along the outer surface of the housing of the flow control valve with one or more clamps or protectors. 14. The flow control valve of claim 12 , wherein the electrically powered actuator comprises an electro-hydraulic actuator comprising an internal piston and wherein movement of the internal piston of the electro-hydraulic actuator causes movement of the piston of the flow control valve to adjust flow through the flow control valve.
