Abstract:
A system for use in a well includes plural flow control devices to control fluid flow in respective zones of the well, where each of at least some of the flow control devices includes a membrane having a permeable material to provide a flow restriction. The membranes of the at least some flow control devices have different permeabilities to provide corresponding different flow restrictions.
