A downhole gravel packing apparatus, comprising: a tubular assembly for being arranged within a wellbore to define an annulus between said tubular assembly and a wall of the wellbore; and a control valve provided within the tubular assembly to control flow of a gravel pack carrier fluid between external and internal regions of the tubular assembly, the control valve comprising a fluid reactant arrangement which reacts with a first fluid to reconfigure the control valve from a first configuration in which flow through the control valve is permitted during a gravel packing operation, and a second configuration in which flow through the control valve is restricted.

Downhole gravel packing apparatus and method

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.
