ABSTRACT:
Improved methods and apparatus for completing an unconsolidated subterranean zone penetrated by a wellbore 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 wellbore in the zone and injecting particulate material into the annuli between the sand screen and the slotted liner and the slotted liner and the wellbore to thereby form packs of particulate material therein to prevent the migration of fines and sand with produced fluids.
