Abstract
A down hole flow control device used in a well bore includes a central mandrel and a packer ring disposed thereon. The packer ring is compressible along a longitudinal axis of the central mandrel to form a seal between the central mandrel and the well bore. Upper and lower slip rings are disposed on the central mandrel and include a plurality of slip segments joined together by fracture regions to form the slip rings. The fracture regions are configured to facilitate longitudinal fractures to break the slip rings into the plurality of slip segments that secure the down hole flow control device in the well bore. The upper and lower slip rings have different fracture regions from one another to induce sequential fracturing with respect to the upper and lower slip rings when an axial load is applied to both the upper slip ring and the lower slip ring.
