Abstract
An adjustable pressure hydrostatic setting module includes a collapsible pressure chamber and a setting chamber. The pressure chamber is precharged at a fluid pressure that is greater than atmospheric pressure and greater than the fluid pressure within the setting chamber. In a described embodiment, the setting module also includes a frangible rupture member that closes off the setting chamber from annulus pressure. A regulator governs the transfer of fluid pressure from the collapsible chamber to the setting chamber.
