drilling jar

Published on: Nov 10 , 2022

We designed every aspect of this double-acting hydraulic jar to withstand the rigors and long hours of challenging applications.

 Featuring an extra-long stroke length for exceptional impact and impulse forces during jarring operations, 

the Double-Acting Fully Hydraulic Drilling Jar  offers infinitely variable trip loads up to the maximum rating of the tool. 

Only a minimal load is required in both the up and down jarring directions, which is crucial in directional, horizontal, and extended-reach wellbores. 

This makes the jar an ideal solution for modern drilling operations.
