Claim 22:
23. A valve assembly for integration within a wellbore string disposed along a wellbore defined within a subterranean reservoir, comprising:
a valve housing comprising a tubular wall defining a passage therethrough and having a housing port extending through the tubular wall for establishing fluid communication between the passage and the reservoir;
a flow controller provided within the passage and adapted to control fluid flow between the passage and the reservoir via the housing port, the flow controller comprising:
an outer sleeve slidably mounted to the valve housing within the passage and having an outer sleeve body defining an outer sleeve passage therethrough, the outer sleeve comprising a sleeve port defined through a thickness of the outer sleeve body and being provided with a flow restriction component adapted to restrict fluid flow through the sleeve port;
an inner sleeve slidably mounted to the outer sleeve within the outer sleeve passage and having an inner sleeve body selectively shiftable within the outer sleeve passage to selectively occlude the sleeve port; and
an occluding sleeve slidably mounted to the valve housing within the passage and adapted to selectively occlude the housing port to control fluid communication between the passage and the reservoir;

wherein the valve assembly is configurable between:
an installation configuration, where the outer sleeve is releasably secured to the valve housing, and the occluding sleeve is positioned in alignment with the housing port to prevent fluid communication between the passage and the reservoir;
an open configuration, where the outer sleeve, the inner sleeve and the occluding sleeve are spaced from the housing port to allow unrestricted fluid communication between the passage and the reservoir; and
a production configuration, where the sleeve port is aligned with the housing port to establish fluid communication between the passage and the reservoir via the sleeve port, and where the inner sleeve body is spaced from the sleeve port within the outer sleeve passage.
