For reliable defense against stuck drillinstrings in highly deviated or high-friction wells, the Wenzel double-acting hydraulic jar (HJDA) offers sturdy and powerful hydraulic, bidirectional action. Variable, operator-controlled impact is achieved thanks to a pair of hydraulic metering valves that feature high-level flow restriction with large passage. The metering device (Visco Jet) ensures consistent delay times over a full range of operating temperatures and delay can be changed by swapping jets. These high-performance valves have been used successfully in the aerospace industry, where precision and reliability is paramount. The HJDA's latch-free design increases the range of jar placement options significantly. It can be used in tension or compression and is an excellent option when available force is not sufficient to jar down with conventional hydraulic mechanical drilling jars. The HJDA is also designed without housing ports to the annulus that could restrict jar stroke, and impact strength and seal integrity. It is also built with just two oil chambers; this reduces the seals required, increasing reliability. Our patented Ultimate configuration substantially increases overpull capacity to the highest in the industry. This design features multiple high pressure chambers to deliver this high overpull capacity, and allow you to make the most of modern rigs and today's premium strength drill pipe. Invest in an insurance policy on which you can rely. Equip yourself with the industry-leading overpull strength of a Wenzel Ultimate drilling jar. This pre-owned tool has been certified to be in good running order by Wenzel Downhole Tools ULC.
