Wireline Hydraulic Jar
Hunting Hydraulic Wireline Jars are normally situated above a set of mechanical link jars.
Hydraulic Jars are used for jarring when difficulty is faced when attempting to obtain a good jar action with mechanical jars, particularly when in deviated wells or wells that contain highly viscous fluids. Hydraulic jars only provide an upwards jarring stroke and are run above the mechanical jars and below the stem
Delivers a controlled upward impact load during wireline operations
The closed hydraulic system makes it possible for the jarring action to be controlled
Available in various diameters and supplied with standard pin byt box connections complete with fishing necks
Controls the jarring action from very light impact to substantial force
