A packer assembly for use within a wellbore. The packer assembly may include a mandrel, a seal assembly disposed about the mandrel, an anti-extrusion assembly disposed about the mandrel proximate the seal assembly to prevent extrusion of the seal assembly, and a deployment system. The anti-extrusion assembly may include a cradle cone that may include a plurality of arcuate surfaces on an exterior of the cradle cone and a plurality of cradle arms. Each cradle arm may include a flexible tip and be positioned on a respective arcuate surface of the cradle cone. The deployment system may be operable to compress the seal assembly such that the seal assembly seals against a wellbore wall and to rotate the plurality of cradle arms such that the flexible tips of the cradle arms contact the wellbore wall to prevent extrusion of the seal assembly.

Packer assembly with an anti-extrusion assembly

A packer system includes a packer assembly and a setting assembly. The packer assembly includes a packer mandrel that includes a shifting profile and an activation profile formed on an inner surface of the packer mandrel and an expandable packer. The setting assembly is positionable within a bore of the packer mandrel and includes a setting mandrel, an activation collet positioned about the setting mandrel and engageable with the activation profile to shear a first shear device and enable the setting assembly to move from a run-in position to an intermediate position, and a setting collet positioned about the setting mandrel and engageable with the shifting profile to shear a second shear device and enable the setting assembly to move from the intermediate position to a setting position where fluid within a bore of the setting mandrel can flow through the setting port to expand the expandable packer.
