Abstract
A hydraulically operated setting tool for use in setting a plug or other component in a wellbore, and which is responsive to a supply of input actuating pressure to actuate the tool. An elongate tool housing has an inlet to receive the supply of actuating pressure, and an actuator element is axially displaceable relative to housing and also engageable with the plug or other component to set and release the component with respect to the wellbore. A pressure multiplier arrangement includes a hydraulically operated low pressure and high volume output piston which performs initial loading of the tool, and a high pressure, low volume output piston which provides a multiplied hydraulic force applied to the actuator element to set the plug or other component in a required position in the wellbore.
