ABSTRACT A tool, e.g., a well packer, for restricting the flow of fluid through an annulus defined by the interior walls of a fluid conduit, e.g., well casing, and the exterior of a tubular member, e.g., the packer mandrel, is disclosed. The novelty of the present invention lies in the deformable packer element of such a tool, wherein in lieu of rubber, a chemically activated material which expands upon contact with fluid in the conduit is employed to effect the desired seal. A method of using such a tool is also disclosed.
