Abstract
A T-shaped slip is retained in an opening of a slip ring to drive the slip in opposed directions to and away from the surrounding borehole wall along a cone. The slip ring and cone do not come together when the slip is engaged. The opening allows release of a lock ring first with the slip engaged followed by release of the slip from the borehole wall. The slip ring and cone come together during removal from the borehole. A travel stop on the axial slip movement is provided to prevent guides on the slip from exiting a track or dovetail on the cone when the slip ring and cone are in contact during removal of the plug or packer. Extension of the guide from the cone track can happen if the slip moves through an enlarged portion of the borehole. The travel stop prevents this.
