Abstract
A setting tool for setting of any of a variety of down-hole devices used in petroleum/gas producing wells. A known setting tool employs an explosive charge. A disadvantage of this tool is that due to safety considerations, when such tools are in use, radio silence must be maintained on the drilling rig. Another known setting tool employs hydraulic forces. A number of problems exist with known tools. The present a setting tool (5a, 5b) includes a timer (35a, 35b), a motor and piston arrangement responsive to the timer, and pressure actuated pistons responsive to the action of the motor and piston arrangement for setting a down-hole device in place at a desired location within a well-bore wherein, in use, the timer is set to a predetermined period of time, the tool in association with the device is conveniently inserted into the well-bore to the desired location, and after the predetermined period has elapsed the timer causes the motor and piston arrangement to actuate so causing the pressure actuated pistons to set the device in place in the well-bore.
