Abstract:
1. A method comprising: introducing a sealant composition as a pumpable slurry into a portion of a subterranean formation, wherein the sealant composition comprises a base fluid, a binder material in an amount from about 0.25% to 9% by weight of the slurry wherein the binder is not a resin or polymer, and a filler material in an amount from about 40% to about 70% by weight of the slurry; allowing the sealant composition to form a cohesive sealant that is at least one selected from the group consisting of ductile, elastic, and nonshrinking, that yields to a stress present in the well bore, and has a permeability in the range of from about 1 to about 1000 miliDarcy; and allowing the cohesive sealant to consolidate at least partially the portion of the subterranean formation.
