A system and method for controlling inflow of fluid into a production
string. In aspects, the invention provides a downhole sand screen and
inflow control device with a gas or water shut-off feature that can be
operated mechanically or hydraulically from the surface of the well. The
device also preferably includes a bypass feature that allows the inflow
control device to be closed or bypassed via shifting of a sleeve. In
embodiments, the flow control device can be adaptive to changes in
wellbore conditions such as chemical make-up, fluid density and
temperature. Exemplary adaptive inflow control devices include devices
configured to control flow in response to changes in gas/oil ratio,
water/oil ratio, fluid density and/or the operating temperature of the
inflow control device. In other aspects of the present invention, inflow
control devices are utilized to control the flow of commingled fluids
drained via two or more wellbores.
