Abstract: A setting tool for setting an auxiliary tool in a well, the setting tool including a housing having a floating piston, the floating piston separating the housing into a pressure chamber, located upstream the floating piston, and a hydraulic chamber located downstream the floating piston; an internal plug having an upstream end attached to the floating piston and having a downstream end extending into the hydraulic chamber; and a cover-insert member covering the downstream end of the internal plug. The internal plug has an internal passage that fluidly communicates (1) with an internal passage through the floating piston, at one end, and (2) with a port at the other end, and the port is covered by the cover-insert member.

Abstract: A sub connects a gun string to a hydraulically activated setting tool for setting an auxiliary tool in a well. The sub includes a housing that prevents a well fluid from entering inside the housing; a plug that covers a hole made in a wall of the housing; and an explosive mechanism located inside the housing and configured to break the plug to open the hole to achieve fluid communication between an outside and the inside of the sub.
