Abstract
System and methods for effectively and efficiently cementing a casing annulus are disclosed. A packer system includes an outer case, a landing collar within the outer case and a slidable shifting sleeve coupled to the landing collar. The landing collar and the shifting sleeve are movable. A connecter coupled to the shifting sleeve and is movable in a movement slot with the shifting sleeve. A rubber element is coupled at one end to the connector and is on an outside surface of the outer case. The displacement of the connector in the movement slot compresses the rubber element.
