Abstract
A packer with a slip assembly utilizing retainable wing projections. The slip assembly is configured for anchoring the packer in a well upon setting. This setting or deployment of the slip assembly involves shearing of wing projections from the sides of the slips. In this way, the retaining of the wings by counterbore projections of the packer ceases to keep individual slips also retained. That is, the shearing now allows the slips to expand radially into the noted anchoring position. Additionally, utilizing this type of wing shearing for setting allows the wings and indeed, the majority of the slips to be of a composite polymer or other readily millable or otherwise removable material. Thus, following the isolation, a more efficient packer removal may be realized.
