A plurality of anchoring elements and seal means are provided for respective anchoring and sealing engagement along the wall of the well in concert and substantially concurrently with one another when the tool is shifted to the set position. The anchoring means are sandwiched in between first and second, or upper and lower, sets of seal means.
