Abstract
Disclosed herein are methods and systems for subterranean zonal isolation, and more particularly to systems and methods of plugging a permeable zone in a wellbore using an elastic sealant composition comprising a cross-linkable polymer, a cross-linking agent, and an elasticity modifier, wherein the elasticity modifier comprises at least one elasticity modifier selected from the group consisting of organophilically-modified clay and/or latex. The elastic sealant compositions may be used for downhole and pipeline applications. For instance, the elastic sealant compositions may be placed into annular space or on top of a packer to seal off fluid flow from water and/or gas zone downhole. The elastic sealant compositions may also be used for pipelines where they may be able to withstand the potential change in diameter without breaking apart. The elastic sealant compositions may be used as pigs for pipelines, for example.
