Title: SACRIFICIAL PROTECTOR SLEEVE
Abstract:
A method of protecting a nipple profile of a downhole tool that forms a portion of a tubing string and that is exposed to through-tubing completion operations includes securing a single-trip protective sleeve to the tool so that the sleeve covers the nipple profile of the tool during the completion operations and dissolving the single-trip protective sleeve so that it breaks away from the nipple profile to expose the nipple profile for use.
