Abstract: A downhole placement tool includes an actuation (122) and a placement assembly. The actuation assembly includes a housing (226a) having a fluid pathway therethrough and an actuation piston seated in the housing to block the fluid pathway. The actuation piston is movable by fluid applied thereto to open the fluid pathway and allow the fluid to pass therethrough. The placement assembly is connected to the actuation assembly (122), and includes a housing (226b) having a pressure chamber (217b) to store the wellbore material (103) therein, a door (219), and a placement piston. The placement piston includes a piston head (264a) slidably movable in the housing, and a rod (264b) connected between the piston head (264a) and to the door (219). The piston head (264a) is movable in response to the flow of the fluid from the actuation assembly (122) into the placement assembly to advance the placement piston and open the door (219) whereby the wellbore material (103) is selectively released into the wellbore.

Abstract: A non-explosive, down hole, setting tool, system method includes a hydraulic fluid reservoir, a first compressible fluid for applying a first force against hydraulic fluid in contact with one side of a setting piston that is movable in the tool, and a second compressible fluid for applying a second force greater than the first force against the other side of the setting piston. Hydraulic fluid is pumped against one end of the setting piston to overcome the second force and move the setting piston. A reset valve is located in a hydraulic fluid return passageway that is connected between other end of the setting piston and the source of hydraulic fluid. The reset valve can move to selectively block the flow of the hydraulic fluid or allow hydraulic fluid to flow through the fluid return passageway, so that the setting piston can move the setting piston back to its start position.
