Downhole Tools
The Junk Sub (Fishing Cup) is a downhole fishing tool used to collect and retain heavy debris that cannot be removed by conventional fluid circulation. Typical junk includes carbide teeth, metal shavings, bearing fragments, and broken tool parts that may settle at the bottom of the wellbore.
By capturing these heavy objects, the junk sub helps maintain a clean well bottom, protects drill bits and BHA components, and reduces the risk of unexpected damage during subsequent drilling operations.
