Abstract
Improved methods of completing subterranean producing zones containing unconsolidated sands penetrated by well bores are provided. The methods are basically comprised of placing a sand screen in the zone, isolating the annulus between the sand screen and the well bore in the zone, introducing particulate solids and foam forming pellets or open cell foam pieces with or without particulate solids and foam forming pellets into the annulus between the sand screen and the well bore to thereby form a formation sand screening permeable pack in the annulus. When utilized, the foam forming pellets are activated by heat or other means to form a foam which expands and solidifies in the pack thereby eliminating voids and strengthening the pack.
