Description
The Casing Swage is an economical method to swage or open collapsed casing. The tool is also used to make a swage run prior to running a production tool to make sure the casing I. D. is clear.
The tool has a long tapered nose which leads the tool through the damaged or collapsed section, and a tapered heel that leads back through the tight spot on retrieving the tool. Generous circulation slots are provided. In certain instances it may be necessary to run a succession of swages, each larger than the previous one, so as to gradually force the casing back to its original I. D.
The tool is usually run with a safety joint, drill collars, bumper subs and jars. Swages are available for all sizes of casing and tubing.
