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.

Abstract: A setting tool for setting an auxiliary tool in a well includes a housing having a floating piston that separates a pressure chamber from a hydraulic chamber; and a plug that is removably located in a through passage of the floating piston. The through passage fluidly connects the pressure chamber to the hydraulic chamber, and the plug prevents a fluid to move from the pressure chamber to the hydraulic chamber or from the hydraulic chamber to the pressure chamber when attached to the floating piston.

Abstract: A configurable composite bridge plug apparatus and method for converting bridge plugs into frac plugs in the field of operation is disclosed. The bridge plug apparatus includes a body with a cylindrical hollow inner mandrel, an upper threaded end and a lower threaded end. A release ring with threads disposed on an outer surface is attached to the upper threaded end. An upper restriction element and a lower restriction element plug both ends of the hollow inner mandrel so that flow is restricted in either directions. A stand-off pin holds the lower restriction element in place. A ball seat inserted proximally to the upper restriction element towards the upper threaded end. A cage retainer is attached to the ball seat with a ball. The configurable bridge plug transformed to a frac plug by removing the upper restriction element and the lower restriction element from the bridge plug.

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.
