Abstract
The present invention provides an expandable packer, and methods for seating an expandable packer. The apparatus comprises an expandable seating body configure to receive a packer body. The seating body is tubular in configuration, and is run into a cased wellbore. The seating body is then set by expanding it into frictional contact with the inner surface of the casing. Thereafter, a packer body is lowered into the seating body. In this respect, the inner surface of the seating body is configured to receive the outer surface of the packer body. The expandable packer can then seal the annulus between one or more tubulars and the casing within the wellbore.
