Drill Stem Testing 5" Hydraulic Jar/Big John Jar in Stock
Features
The hydraulic jar is included as part of a toolstring to help remove stuck tools. The jar helps free a
stuck tool or toolstring by resisting a pull on the workstring. When the workstring is stretched by
the pull, tension in the jar is released and an upward impact is delivered to the stuck tool.
Features and Benefits
• Design of the hydraulic system ensures long life with little maintenance.
• Rig time is reduced.
• Jar can be recocked rapidly.
• Jar time delay is adjustable.
• Amount of pull to trip the jar can be varied within the limits of the time-delay system.
