Abstract
Methods for positioning an expandable metal sealing element in the wellbore. An example method includes an expandable metal sealing element having a reactive metal and disposed in a location. The method further includes actuating a washout prevention element, contacting the expandable metal sealing element with a fluid that reacts with the reactive metal to produce a reaction product having a volume greater than the reactive metal, and allowing the washout prevention element to prevent at least a portion of the reaction product from flowing away from the location.
