Project Description

Ultimate Double Acting Hydraulic Drilling Jar

Using proprietary new technology, Wenzel Downhole has been able to dramatically increase the allowable overpull force. The Ultimate Double Acting Hydraulic Drilling Jar (UHJDA) is a bi-directional drilling jar incorporating hydraulic delay without a latch mechanism.  This jar will allow the operator to apply variable impact in both the up and down directions.  The UHJDA is intended for use in highly deviated or high friction wells, where conditions may prevent applying sufficient force to release a mechanical latch.
