FISHING BUMPER SUB

TECHNICAL SUMMARY

The KXZ Fishing Bumper Sub is a mechanical jarring tool for stuck drill string remediation. It delivers repeated jarring to free stuck points; if jarring/lifting fails, it rotates to assist releasing fishing tools. Paired with internal cutters, it provides constant feed force for stable cuts; with back-off tools, it compensates for post-backoff thread stroke. It fits API connections (NC38/NC50) for onshore/offshore fishing operations.
