Methods and apparatus for completing wells in unconsolidated subterranean zones

摘要

A well bore (10) penetrating an unconsolidated subterranean zone (12) is completed by placing in the zone a slotted liner (20) having an internal sand screen (21) disposed therein. The slotted liner and well bore in the zone are isolated and particulate material is injected into the annulus (22) between the sand screen and the slotted liner and into the annulus (23) between the slotted liner and the well bore, to thereby form a pack of particulate material to reduce or prevent the migration of fines and sand with produced fluids.
