• Bowen™ Full-Flow Reverse Circulation Junk Baskets


    The Bowen™ Full-Flow Reverse Circulation Junk Basket is similar to the standard Reverse Circulation Junk Basket and is also used to retrieve small junk objects in well bores. The difference is that the Full-Flow type has a unique valve assembly which allows circulation through the center to keep out shale or debris while running in the hole. A drain through the tool eliminates the possibility of pulling a wet string even though the inner barrel is plugged by the core.


    During operation, the ball is dropped to the valve seat. Pump pressure then causes pins to shear which opens the reverse circulation cavity to circulation. Fluid flows through the inner passage of the barrel, out the vents in its lower end, outward and downward deflected toward the center in a continuous stream, and up through return ports in the upper end of the barrel. All junk is thus carried into the barrel above the junk catchers.


     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.



    Two Junk Catchers are 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 also converted into a Fishing Magnet by replacing the catchers with a Bowen Magnet Insert.
