Patent

CA 2314392

Improved methods and apparatus for completing an unconsolidated subterranean zone penetrated by a well bore are provided. The methods basically comprise the steps of placing a slotted liner having an internal sand screen disposed therein in the zone, isolating the slotted liner and the well bore in the zone and injecting particulate material into the annuli between the sand screen and the slotted liner and the slotted liner and the well bore to thereby form packs of particulate material therein to prevent the migration of fines and sand with produced fluids.
