    摘要: Methods and apparatus are provided for performing an expedited shoe test using an expandable casing portion as an annular fluid barrier. Such an expandable annular fluid barrier may be used in conjunction with cement if so desired but cement is not required. Further provided are methods and apparatus for successfully recovering from a failed expansion so that a shoe test can be completed without replacement of the expandable casing portion.
