Abstract: A pressure actuated module associated with a subterranean tool is set with pressure in the well annulus supplemented by added pressure. The addition of pressure to the hydrostatic opens access to a setting piston that is referenced to a low pressure chamber. The piston strokes to a travel stop reducing the volume of the atmospheric chamber while setting the tool. After the tool is set the annulus is communicated to the low pressure reference chamber for the actuating piston to remove a residual net force on the setting piston after the set. One way to do this is to sequentially break multiple rupture discs at different pressures. Another is to have a degradable member in the atmospheric chamber. A piston is fixed in place during setting, and shifts with the application of additional pressure allowing pressure to pass through a port between the annulus and the atmospheric chamber.
