Abstract

The present invention provides an apparatus and method for sealing and/or anchoring against the inside surface of an outer tubular. In one embodiment, a radially expandable sleeve has at least one radially expandable separate rings located there about. The at least one ring is capable of radial expansion without appreciable deformation of the at least one edge for improved engagement between the at least one edge and the inside surface of the outer tubular. In another embodiment, the present invention provides an inflatable metal to metal seal packer that is able to accommodate out of round casing.
