ABSTRACT:
A method and apparatus for forming an elastic memory foam into an expansion element with an outer diameter larger than a borehole, heating the expansion element to its transition temperature and compressing it to a smaller run-in diameter, cooling the compressed expansion element below its transition temperature and running it into the borehole, then raising the expansion element to its transition temperature to cause it to expand and seal against the borehole wall. Expansion can be enhanced by expanding a mandrel on which the expansion element is formed.
