Abstract
A packer for sealing a space downhole in a well. The packer includes a deformable sheath having a body and first and second ends for defining an interior volume proximate to a tool surface. A material located within the interior volume is deformable, when the sheath second end is moved toward the sheath first end, to move the deformable sheath into the downhole space. The sheath can function as a sealing element or a backup element, and can be applied to different structures and tool configurations downhole in a wellbore. One or more deformation surfaces can selectively contact the sheath body to shape the deformation of the sheath body during the setting process.
