ABSTRACT:
Phase-controlled well flow control. A well system includes a flow control device which regulates flow of a fluid in the well system, the flow control device being responsive to both pressure and temperature in the well system to regulate flow of the fluid. A flow control device includes a flow regulator for regulating flow of a fluid through the flow control device, and an actuator which is operative to actuate the flow regulator in response to a predetermined relationship between a phase of the fluid and both pressure and temperature exposed to the actuator. A method of controlling a phase change of a fluid in a well system includes the steps of: flowing the fluid through a flow control device in the well system; and adjusting the flow control device in response to both pressure and temperature in the well system.
