ABSTRACT:
An emergency casing support utilizes a conventional casing hanger. Casing hanger lands on a wellhead housing internal landing shoulder. The emergency support secures to the lower end of the casing hanger. The emergency support has a body which carries a slips bowl. Body also carries a seal for sealing between the casing and the body. A sleeve nut is engaged by a setting tool lowered through the casing hanger into the body. The sleeve nut when rotated causes the bowl to move upward relative to the slips and also energizes the seal.
