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.

Downhole flow control device and method

A downhole flow control device includes a housing, an inlet port, an outlet port and a valve seat surface surrounding the inlet port. A valve plate is mounted within the housing to move between an open position in which the valve plate is separated from the valve seat surface to define a separation flow path therebetween to permit flow in a forward direction from the fluid inlet to the fluid outlet, and a closed position in which the valve plate is engaged with the valve seat surface to close the separation flow path to restrict flow in a reverse direction from the fluid outlet to the fluid inlet. At least one of the valve seat and valve plate defines a geometry to encourage an increase in static pressure of fluid flow in the separation flow path when the valve plate is in the open position.

Downhole flow control device

A downhole flow control device includes a body to be secured within a wall of a tubular, wherein the body defines a flow path therethrough, with a nozzle mounted within the flow path. A dissipation structure is positioned on a first side of the nozzle, such that fluid flowing through the body in a first direction will exit the nozzle and impinge on the dissipation structure prior to exit from the flow control device.
