Abstract:
A downhole flow control device is described having a flow control valve and a sensor communication with the flow control valve. The sensor measures a downstream process parameter and the flow control valve is configured to control the fluid flow through the valve to achieve a target downstream process parameter value in response to the measured downstream process parameter. A control system for controlling the downhole flow control device and a method for controlling the downhole flow device are also provided.
