Abstract
A downhole tool and method, of which the downhole tool includes a housing defining a charge chamber and a hydraulic chamber, the hydraulic chamber containing a hydraulic fluid, and a piston disposed in the hydraulic chamber. The piston prevents the hydraulic fluid from communicating with the charge chamber, and is in communication with the hydraulic fluid and the charge chamber. The tool also includes one or more charges disposed in the charge chamber. The one or more charges are configured to ignite and thereby expand a gas in the charge chamber. The tool further includes a fluid-metering device coupled to the housing. The fluid-metering device is configured to control a rate at which the hydraulic fluid is pressed out of the hydraulic chamber.
