    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.

    Abstract: Steam injection pipe string apparatus is disclosed comprising an elongated tubular structure with first and second ends, and a plurality of orifices formed in the elongated tubular structure. The sizes of the orifices vary from one end of the elongated tubular structure to the other, and, in one embodiment, the sizes of the orifices increase from one end of the elongated tubular structure to the other. The elongated tubular structure may comprise a plurality of blank pipes in threaded engagement with one another or a plurality of subs with different sized orifices in the subs. The orifices may be formed in the elongated tubular structure using milling techniques or by inserting a nozzle in a threaded aperture formed in the structure. A system utilizing the steam injection pipe string apparatus is especially suitable for use in a steam assisted gravity drainage system.
