Abstract

A synergistic barrier formation, including a matrix material with expandable metal particles dispersed homogeneously therein. A method of forming a synergistic barrier formation, including forming a wellbore barrier on a conduit disposed in a wellbore; the wellbore barrier including expandable metal particles, and exposing the wellbore barrier to water, acid, saline or heat. A method of forming a pack, including forming an expandable metal sleeve on the conduit, wherein the expandable metal sleeve comprises expandable metal particles, forming a swellable rubber sleeve on the conduit at a location distal to the expandable metal sleeve, exposing the expandable metal particles to water, acid, saline or heat causing the expandable metal sleeve to corrode to form corroded metal particles, detaching the corroded metal particles from the expandable metal sleeve, and consolidating the corroded metal particles on the swellable rubber sleeve.
