Abstract (en)
Methods and apparatus for completing an unconsolidated subterranean zone penetrated by a well bore (510) are provided. The methods basically comprise the steps of placing a pre-packed screen (521) having an outer screen and an inner screen in the zone whereby an annulus (522) formed between the inner and outer screen is packed with sand, placing a shroud (520) in the zone, isolating the screens (521), shroud (520), and well bore (510) in the zone, and injecting particulate material into the annuli between the outer screen and the shroud (520) and between the shroud (520) and the well bore (510) to thereby form packs of particulate material therein to prevent the migration of fines and sand with produced fluids. <IMAGE>
