ABSTRACT:
A wire line well tool is connected to a fluid gun which is run into the hole along with the tool. Should the tool become stuck, the gun is actuated, e.g. electrically, to direct mud active fluid around the stuck tool and the inside of the well bore, to destroy the pressure imbalance about the tool and to exert a radial force pushing the tool toward the center of the hole to free same.
