ABSTRACT:
An adjustable swage features an ability to enhance a radial collapse force when an obstruction in a tubular is encountered to allow radial contraction so that the obstruction can be cleared. The movable segments are configured to elastically bend on high loading so as to create additional radial component force to aid the adjustable swage in reducing its size to clear the obstruction.
