Beschreibung
Zusammenfassung:	A method of producing hydrocarbon fluid from an underground reservoir through a generally horizontal well having an inlet portion in communication with a pay zone of said formation and a riser portion extending from the inlet portion in said underground reservoir to the surface is disclosed. The underground formation includes at least one fluid in addition to said hydrocarbon fluid. The method includes providing at least one pressure responsive inlet flow control device in the horizontal production well between said inlet portion and said riser portion. The method includes controlling a pressure difference between an upstream side of the pressure responsive inlet flow control device and the underground reservoir by using the pressure responsive inlet flow control device. Then the method includes permitting preferential production of said fluid hydrocarbons as compared to said at least one other fluid. An apparatus for providing a pressure responsive inlet flow control device is also comprehended.
