Abstract
A packer assembly includes a tubular having a surface, a gauge ring provided on the surface, a back-up ring positioned adjacent the gauge ring, a packer element arranged adjacent to the back-up ring, an expansion ring arranged adjacent to the gauge ring, the expansion ring including a step portion, and a support ring arranged axially between the back-up ring and the expansion ring. The support ring includes a step feature. The step portion and the step feature are selectively engaged with expansion of the packer element to form an interlock feature that substantially limits rocking of the expansion ring.
