Abstract
A casing hanger support assembly supports an inner casing string within a well containing an outer casing string and a production tubing string. The casing hanger support housing supports the casing hanger in the well, with a casing hanger being secured to an upper end of the inner casing string. One or more of a rupture disk and a blowout plug are provided in a wall of the casing hanger support housing for maintaining the desired pressure differential between an annulus within the outer casing string and an annulus exterior of the outer casing string, thereby preventing casing collapse or burst.
