Junk Catcher - Internal Fishneck
To reduce debris on top of sub surface tools.
BT Junk Catchers are made up of 2 components:
1. Fishneck 2. End Cap
Tighten end cap onto fishneck and attach to GS running / pulling tool and hoist inside of lubricator. Lower into wellbore to top of sub surface tool, jar down to shear GS. Remove tool string from wellbore.
If a large amount of debris is expected, an extension barrel may be added to accommodate added volume. Ensure that jarring down to release the junk catcher will not damage equipment below.
