Multi-function well service system

Abstract

A system for placing a tool in a production string. The system uses a tubular connection location, like a no-go landing nipple, and a second tool driven by deformable balls. The second tool will be a work tool and may be a jar, perforation tool or other well service tool. The work tool will have a locking mandrel associated with it, and the locking mandrel will utilize a funnel, sized to seat a deformable ball. A number of different deformable balls having different characteristics may be used. Some balls may push the entire second tool to a location within the no-go landing nipple, while others may be utilized to extend locking keys from slots to lock the second tool in place. Balls may, at high pressure, be deformed such that they can pass through the funnel, allowing fluid pressure to be utilized for other tasks within the tool.
