Abstract
A method for sealing perforation tunnels in a well includes steps of pumping an initial volume of fluid into the well, mixing expandable material into a carrier fluid to form an expandable fluid mixture, pumping the expandable fluid mixture into the well to force the expandable material into the perforation tunnels in the well, and holding the expandable material under a hold pressure in the perforation tunnels for a cure period to form perforation plugs.
