- High over-pull capability (with additional safety factor)
- Greater than conventional jars of the same size
- Longer free stroke
- No other jar has a greater free stroke
- Higher impact capability
- It can hit harder than any other jar the same size
- Hydraulic timer is self-compensating for hole temperature
- Resulting in more consistent pull times
- Mechanical up cocking lock prevents accidental cocking of the up jar section and firing of the down jar section
- Lock is adjustable from 5,000 lbs. up to any practical maximum
- Jar has rugged V-packing for extended service
- Jar can be used for high temperature service with minimum packing changes
- Jar has high tensile strength for higher impact service capability
- Tapered end connections allow jar to transverse smaller hole radii as well as reduce fatigue damage to the tool
- Optional “ZIP” lift or elevator lift shoulders available on upper end of jar for ease of use
- Jar is fully pressure balanced against hydrostatic pressure
- Jar’s large pump open area allows the tool to be run in compression
- Jar will not automatically cock or fire with the pumps in normal drilling
- Hydrostatic pressure strengthens jar
- More over-pull capability with increasing hole depthSplines are constantly engaged
- No rotary slack to cause directional drilling problems
- Straight push and pull operation for easy jar operation
- Torque trapped in drill-string doesn’t effect jar operation
- Large through bore for passage of instruments
- Negligible pressure drop through jar
- Massive over-pull failure results on internal washpipe collapse
- No parting of tool and no washout (Jar acts as a bumper sub)
- Packing is preloaded to prevent low pressure leakage and seal compression set problems
- Seals maintain sealing capability at any pressure (including at zero pressure)
- All connections, shoulders and tensile/torque carrying parts are a fatigue resistant design. Additionally, the parts are cold worked to provide additional fatigue resistance (shot peened)
