Abstract
An actuator including an impulse generation arrangement including an atmospheric pressure chamber, and a valve connected fluidly to the chamber, a prime mover arrangement including a device piston, and a hydrostatic pressure source, and a hydraulic chamber disposed between and fluidically connecting the impulse generation arrangement and the prime mover arrangement. A method for actuating a downhole tool including signaling the trigger in an actuator, opening the atmospheric chamber of the actuator, causing a low pressure pulse in the actuator, and moving the device piston with the pulse. A borehole system including a borehole in a subsurface formation, a string in the borehole, and the actuator disposed within or as a part of the string.
