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.

Expandable packer assembly and setting assembly

A downhole tool includes an outer tubular member and an inner tubular member. The outer tubular member may have one or more screens coupled thereto, a packer coupled thereto, and a shunt tube isolation valve coupled thereto. A first sleeve may be coupled to the packer and move from a first position to a second position. The packer may actuate into a set state when the first sleeve is moved to the second position, and the packer may isolate first and second portions of an annulus from one another when in the set state. A shunt tube may be coupled to the packer and provide a path of fluid communication from the first portion of the annulus, through the packer, and to the second portion of the annulus when the packer is in the set state.

System and method for actuating downhole packers

Packers and methods of using same are described. The packer includes a packer body, a slip to engage a casing of the well and a sealing element to seal an annulus of the well, a fluid bypass chamber adapted to allow fluid passage through the packer body during run in hole and in release position, and a re-settable mandrel slideably engaged with guide pins attached to the packer body and adapted to selectively open and close circulation paths upon actuation. This abstract allows a searcher or other reader to quickly ascertain the subject matter of the disclosure. It will not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b).
