JUNK SUB

TECHNICAL SUMMARY

Designed for onshore/offshore drilling operations, this junk sub targets heavy drill cuttings or metal debris that standard mud circulation can’t remove from the wellbore. Its detachable cup body simplifies debris retrieval, cleaning, and maintenance—supporting continuous while-drilling use when connected to the drill string.

The cup’s tight clearance with the wellbore slows mud flow at the cup opening, creating a vortex that traps heavy debris inside, purifying the drilling fluid. Compatible with various wellbore sizes (across models like LB94 to LB340), it boosts drilling fluid cleanliness, reducing wear on downhole tools and lowering debris-related operational risks.
