Abstract
The embodiments include methods and tools to activate downhole apparatuses. In one embodiment, a hydrostatic pressure intensifier includes a housing having at least two different internal cross-sectional surface areas. The housing includes a device mounted on the housing and operable to actuate in response to being subject to a threshold amount of pressure. The housing also includes a first piston housed in a first chamber of the housing, where the first piston has a first cross-sectional area and a first stroke length, and a second piston housed in a second chamber of the housing, where the second piston has a second cross-sectional area and a second stroke length, and where the first cross-sectional area is greater than the second cross-sectional area. The hydrostatic pressure intensifier also includes a fluid flow restrictor that restricts fluid flow through the valve to control an amount of pressure applied by the first piston.
