Hydraulic Jars
Available out of Provost, Kindersley, and Weyburn.
Use Cases:
Intended for fishing, coring and milling applications but tough enough for drilling applications
Delivering impact force to free stuck pipe, tools, or assemblies
Impact force is controlled by a metering device that ensures consistent delay times over the full range of operating temperatures
A long, splined mandrel ensures the jar is not affected by torsional forces, the spline is sealed and lubricated to minimize friction and extend tool life
Free stroke of 4″ to 6″ (depending on tool size) provides an impact force to the stuck point several times higher than the overpull force applied to the jar
Standard seals are effective to 250ºF (120ºC), and the HJ can be dressed with seals effective to 400ºF (200ºC) for hot hole environments
All external sealing surfaces are coated with wear and corrosion resistant tungsten carbide
