An inflatable packer construction where the inflatable elastomer element is; (1) constructed from the same type of rubber compound from end-to-end the rubber is cured differentially from end-to-end so that inflation is from one end to the other end; (2) is constructed of rubber having different characteristics from end-to-end so that the cured rubber will inflate from one end to the other end; (3) is constructed of rubber having a release agent between one end of the rubber and a mandrel so as to release one end of the rubber first from the mandrel upon inflation; (4) is constructed of rubber having different thicknesses from end-to-end so that one end inflates sooner than the other end; or (5) is constructed of rubber with a segment of the length of the element having a releasably confining element.
