Abstract
A technique enables control over anti-extrusion layer movement during packer inflation. A packer employs a packer nipple having an exterior which uniquely engages distinct layers of the packer. The exterior comprises a plurality of distinct retention features, and each retention feature is designed to engage a specific layer of the packer. An individual retention feature can be uniquely designed to secure an anti-extrusion layer.
