  • HEATERS TO ACCELERATE SETTING OF EXPANDABLE METAL
    Publication number: 20210222509
    Abstract: Provided is a method for setting a downhole tool, and a downhole localized heater. The method, in at least one aspect, includes positioning a downhole tool within a wellbore, the downhole tool including expandable metal configured to expand in response to hydrolysis, and positioning a downhole localized heater within the wellbore, the downhole localized heater being proximate the expandable metal. The method additionally includes subjecting the expandable metal to a wellbore fluid to expand the expandable metal into contact with one or more surfaces while activating the downhole localized heater to create a temperature spike and accelerate an expansion of the expandable metal.
