AI Technical Summary
Technical Problem
In wellbore applications, expandable metal used for pressure isolation can allow gas migration through interstitial spaces, compromising its effectiveness.
Method used
Incorporating non-reactive colloid particles into the expanded metal, which form colloidal dispersions and fill interstitial spaces, thereby reducing or eliminating gas migration.
Benefits of technology
The inclusion of colloid particles significantly reduces gas migration through the expanded metal, enhancing its effectiveness in pressure isolation applications.

Abstract
Provided is a well system, and a method. The well system, in one aspect, includes a wellbore positioned within a subterranean formation, as well as a downhole tool positioned within the wellbore. The downhole tool, according to one aspect, includes a housing, as well as an expandable metal member positioned about the housing, the expandable metal member comprising a metal configured to expand in response to hydrolysis. The well system, in one further aspect, includes a reactive colloidal dispersion of colloid particles surrounding a surface of the expandable metal member.
