Zusammenfassung:A method of cleaning wellbore flow control apparatus 40 comprising; at least one screen 62 and at least one inflow control device 50 where there is provided a fluid inflow path through the screen/s and from an outer portion to an inner portion of the inflow control device/s and delivering treatment fluid to the inflow control device/s so the fluid flows in a reverse direction along the fluid inflow path. A treatment tool may be inserted into the wellbore to deliver the treatment fluid and back wash / flush the apparatus. A second independent claim concerns flow control apparatus comprising a screen and first and second inflow control devices. A locator 82 may be present to allow a treatment tool to align with the inflow control device.
