Abstract
A force balancing system for use with a well bore tool, such as a drilling tool, is provided. The tool may be connected to a drill string, and the force balancing system is adapted to decouple the weight of the drill string from the operation of the tool. The force balancing system utilizes hydraulic or pneumatic pressure to advance the tool into the well bore, while preventing excessive weight from being applied to the tool.
