A completion technique to replace cementing casing, perforating, fracturing, and gravel packing with an open hole completion is disclosed. Each zone to be isolated by the completion assembly features a pair of isolators, which are preferably tubular with a sleeve of a sealing material such as an elastomer on the outer surface. The screen is preferably made of a weave in one or more layers with a protective outer, and optionally an inner, jacket with openings. The completion assembly can be lowered on rigid or coiled tubing which, internally to the completion assembly, includes the expansion assembly. The expansion assembly is preferably an inflatable design with features that provide limits to the delivered expansion force and/or diameter. A plurality of zones can be isolated in a single trip.
