Abstract: A flow control apparatus (100) for controlling the inflow of production fluids (134, 140) from a subterranean well includes a tubular member (118) having at least one opening (138) that allows fluid flow between an exterior of the tubular member (118) and an interior flow path of the tubular member (118) and a flow restricting device (120) operably positioned in a fluid flow path between a fluid source and the at least one opening (138). The flow restricting device (120) includes a valve (128, 130) and an actuator (126). The actuator (126) includes a material that swells in response to contact with an undesired fluid (140), such as water or gas. The flow restricting device (120) is operable to autonomously reduce the fluid flow through the flow control apparatus (100) in response to contact between the material and the undesired fluid (140).
