Jet Type Junk Basket

The Gotco Jet Type Junk basket is designed to recover objects from the bottom of the well bore. This superior tool removes items such as slips, hand tools, rock bit cones, and any other small pieces of junk from the well.

Construction

The tool consists of a top sub, jet barrel, lower barrel, jet assembly section, jets, ball seat, drop ball, shoe, and catcher assembly. A lift sub is available to assist in handling and for storage of the steel drop ball.

Assembly and Operation

Make up the junk basket to the bottom of the string and run into the hole.(see Figure 1 - below) When the tool is approximately 4 to 6 feet off the bottom of the hole, circulation is initiated to wash the hole in order to retrieve junk. During this operation, the ball seat is secured in place within the upper portion of the jet pump head with shear pins. This seals off the reverse circulation jet ports providing full circulation through the entire length of the tool. The barrel, jet assembly, and junk catchers will be washed clean going into the hole while preparing for junk retrieval.

When the tool is over the fish (junk), the steel drop ball is then dropped through the inside diameter and seats inside the ball seat. (see Figure 2 - below) When pump pressure is applied, the pins will shear allowing the ball seat top drop down into the lower section of the jet pump head. The flow will now be directed out of the jey nozzles at an angle as to not washout the hole. Flow will then be directed downward and back up through the junk basket catcher, lower barrel, jet housing, around the jet nozzles, and back out of the jet barrel ports. thus, creating reverse circulation and directing junk into the catcher assembly.

The Jet Type Junk Basket can easily be coverted to a standard Core basket by simply removing the Jet Barrel and Jet Assembly and screwing the Lower Barrel directly to the Top Sub.

O.D. Conversion and Accessories

The Lower Barrel can be replaced by an oversized barrel in order to adapt to a larger junk catcher assembly. There are four types of mill shoe's available to fit the Jet Type Junk basket. Type A, B, C, and the Finger Type Shoe. See standard Shoes in Reverse Circulation Junk basket Section on page 22 of our catalog.
