Flow Control Apparatus

A method of treating a flow control apparatus in a wellbore, the method comprising:

• running a treatment tool into downhole tubing incorporating at least a first inflow control device and an associated screen;
• locating the treatment tool adjacent the flow control device;
• delivering treatment fluid through the treatment tool such that the treatment fluid flows through the flow control device and contacts the screen.

A flow control apparatus for use in a wellbore, the flow control apparatus comprising:

• a screen;
• a first inflow control device and a second inflow control device, the apparatus providing a fluid inflow path through the screen and from an outer portion to an inner portion of each inflow control device, and the apparatus being configurable to provide a treatment fluid path extending from an inner portion to an outer portion of the first inflow device, along the screen, and then from an outer portion to an inner portion of the second inflow device.
