Abstract
A ball seat is expanded and held in place within a casing using an expander. The ball seat includes one or more gripping elements and one or more sealing elements. An apparatus for expandably installing a ball seat in a casing includes a ball seat having one or more gripping elements and one or more elastomeric sealing elements disposed on an exterior of an expandable sleeve portion of the ball seat that is expanded by pulling an expander into the bore of the expandable sleeve portion of the ball seat. A mechanical fuse is predisposed to fail at a level of force sufficient to move the expander to the installed position. Failure of the fuse and further movement of a pulling mandrel positions a channel on the mandrel into alignment with a distal end of the collet, enabling the collet to collapse and pass through the expander for removal.
