Abstract
A well system can include a flow control device which regulates flow of a fluid from an interior of the device outwardly through an exit port, and a deflector which outwardly overlies the exit port and provides fluid communication between the exit port and an annulus formed radially between the deflector and a wellbore lining. The deflector can diffuse the flow of the fluid prior to impingement on the wellbore lining. A flow control assembly can include a flow control device which regulates flow of a fluid from an interior of the device outwardly through an exit port, and a deflector which outwardly overlies the exit port, the deflector including at least one opening, and the opening being circumferentially offset relative to the exit port. A form of an interior surface of the deflector and/or an exterior surface of the flow control device can diffuse the flow of the fluid.
