Abstract
A device and method of repairing a damaged portion of a seal bore interconnected in a tubing string, where the device can include a chamber, a piston positioned within the chamber, and a filler material contained within the chamber. A force applied to the piston can cause the piston to move within the chamber, which can cause at least a portion of the filler material to be expelled from the chamber, with at least a portion of the expelled filler material filling a recess in the damaged portion of the seal bore, thereby repairing the sealing surface of the seal bore.
