ABSTRACT:
Seal elements for use on well packers having multiple mandrels for sealing between the packer and the inner wall of a well pipe. The seal elements (center elements and/or end elements) are provided with voids therein for controlling the stresses created in the elements during setting of the packers while minimizing the strains resulting from such stresses. The voids are preferably cavities and are readily formed in the elements as they are molded.
