Abstract

A hydraulically activated setting tool for setting an auxiliary tool in a well, the setting tool including a housing that prevents a well fluid from entering inside the housing; a floating piston placed inside the housing and closing an end of a pressure chamber; an attached piston placed inside the housing and configured to actuate the auxiliary tool; a fluid chamber located between the floating piston and the attached piston, wherein the fluid chamber holds a fluid; and a communication element configured to establish a fluid communication between an outside and an inside of the housing. The fluid communication makes a well fluid in the well to directly act on the floating piston.
