FISHING TOOLS
Junk Baskets
Bowen Reverse Circulation Junk Baskets
The NOV Downhole Bowen® Reverse Circulation Junk Basket is used to retrieve all types of
small junk objects in well bores. This tool’s unique principle of reverse circulation insures complete
recovery of all junk and eliminates mis-runs. A drain through the tool also eliminates the possibility
of pulling a wet string even though the inner barrel is plugged by the core. In addition, it may be
converted into an effective fishing magnet and still retain the reverse circulation feature.
Top Sub
A single junk catcher is used in each assembly. A lifting sub is provided for ease of handling which
includes a storage space for the steel ball used in the operation of the tool. It is converted into a
fishing magnet by replacing the catcher with the Bowen magnet insert.
Valve Cup
Alternate Shoes available are the Type B and Type C. The Type B shoe is similar in design to Type A
but dressed with Itcoloy. The Type C is flat bottomed and dressed with Itcoloy.
Steel Ball
Valve Seat
During operation, with the steel ball dropped into the valve seat, fluid flows through the inner
passage of the barrel and out the vents in its lower end. The fluid is directed outward and downward
and deflected toward the center. Fluid flows in a continuous stream to the center of the tool and up
through return ports in the upper end of the barrel. All junk is thus carried into the barrel above the
junk catcher.
