Abstract
Official abstract text for this publication.
A packer device for forming a fluid seal between an inner tubular member and an outer tubular member. The packer device includes a swage assembly that is expandable from a reduced diameter condition to an expanded diameter condition and a substantially deformable packer element for contacting and forming a fluid seal against a surrounding tubular. The packer element radially surrounds the swage assembly and being moved outwardly into a sealing configuration when the swage assembly is moved to its expanded diameter condition.
