Abstract
An annular packer device that is expandable in an annulus between an inner body and an outer boundary. The annular packer is sealingly movable along at least one of the inner body and the outer boundary. A method of sealing an annulus formed between a pipe and a borehole in a subterranean well can include positioning an annular packer sealingly around the pipe, expanding the packer into sealing engagement with the borehole, and permitting the pipe to displace relative to the packer while the packer remains sealingly engaged with the borehole.
