Abstract
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 with dividers extending between the screen and liner, isolating the slotted liner and the well bore in the zone and injecting particulate material into flow paths formed by the dividers between the sand screen and the slotted liner and into the annulus between 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.
