ABSTRACT:
A tool for actuating a subsurface well tool located within a well bore by metering the force applied by hydrostatic pressure within the well bore is disclosed. The tool is actuated in response to an external signal whereby hydrostatic pressure is applied to a hydraulic fluid contained within the tool. The hydraulic fluid is metered to apply a prescribed actuating force to a piston with a metering orifice determining the rate at which force is applied to the actuating piston and to the well tool.
