Abstract
A downhole flow control device comprises a body locatable within a wall of a tubular, wherein the body defines a flow path therethrough to accommodate flow in reverse first and second directions between internal and external locations of the tubular in use. The downhole flow control device further comprises a regulator member mounted within the body and being moveable between first and second positions in accordance with flow direction through the body. The regulator member is locatable in the first position during flow through the body in the first direction to provide a first restriction to flow. The regulator member is locatable in the second position during flow through the body in the second direction to provide a second restriction to flow.
