Ultimate Hydraulic/Mechanical Drilling Jar

The Ultimate Hydraulic/Mechanical Drilling Jar (UHMJ) is a double acting jar, designed to deliver hydraulic delay when jarring in the up direction, and mechanical release when jarring in the down direction. Using proprietary new technology, Wenzel Downhole Tools has been able to dramatically increase the allowable overpull force. The UHMJ incorporates a latch mechanism to keep the jar locked in the neutral position and eliminate unexpected jarring while tripping or racking on the derrick.

Features and Benefits

• The UHMJ is normally operated in the latched position to reduce unexpected jarring while drilling and eliminate movement between jar components, increasing service life.
• The UHMJ operates with a simple up and down motion and is not affected by torque.
• The spline drive and latch mechanism are enclosed in a single, sealed oil chamber without ports to the annulus. Such ports on other jars may fill with cuttings and restrict the down jar stroke.
• The hydraulic delay mechanism is located in a separate chamber to prevent contamination and increase reliability.
• With the latch mechanism in the latched position, the inner mandrel and outer housing act integrally, virtually eliminating seal and inner tool wear during normal drilling conditions. There is no need to extend or open the jar before running in the hole.
• Standard seals in the tool are effective to 250ºF (120ºC). The UHMJ can be dressed with seals effective to 400ºF (200ºC) and above for hot hole environments. External sealing surfaces are tungsten carbide-coated to enhance wear and corrosion resistance.
• The UHMJ can be run in tension or in compression within the preset latch settings.

Ultimate Double Acting Hydraulic Drilling Jar

The Ultimate Double Acting Hydraulic Drilling Jar (UHJDA) is a bi-directional drilling jar incorporating hydraulic delay without a latch mechanism. This jar will allow the operator to apply variable impact in both the up and down directions. Using proprietary new technology, Wenzel Downhole Tools has been able to dramatically increase the allowable overpull force. The UHJDA is intended for use in highly deviated or high friction wells, where conditions may prevent applying sufficient force to release a mechanical latch.

Features and Benefits

• The UHJDA is hydraulically controlled and jars in both directions, with impact force controlled by the operator.
• Impact force is controlled by a metering device that ensures consistent delay times over the full range of operating temperatures.
• The UHJDA operates via a simple up and down motion and is unaffected by right- or left-hand torque.
• Standard seals are suitable for use up to 250°F (120°C). Optional high-temperature seal kits are available for service to 400°F (200°C) and above. External sealing surfaces are tungsten carbide-coated to enhance wear and corrosion resistance.

Operation

Jarring Up

• With the jar in the neutral position, apply the desired overpull in excess of the free string weight, starting the hydraulic delay sequence. At the end of the hydraulic delay, the jar will release causing an upward impact force.
• If necessary, lower the drill string sufficiently to close the jar to the neutral position, ready to jar up again.

Jarring Down

• With the jar in the neutral position, lower the drill string to apply the desired downforce, starting the hydraulic delay sequence. At the end of the hydraulic delay, the jar will release causing a downward impact force.
• If necessary, raise the drill string sufficiently to open the jar to the neutral position, ready to jar down again.

Enhanced Hydraulic Mechanical Drilling Jar

The Wenzel Downhole Tools Enhanced Hydraulic/Mechanical Drilling Jar (EHMJ) is a double acting jar, designed to deliver hydraulic delay when jarring in the up direction, and mechanical release when jarring in the down direction. The EHMJs offer higher latch settings and smaller pump open area than our standard HMJ. These jars are well suited for working in wells with high weight on bit and high pressure drop across the bit.

Features and Benefits

• The EHMJ is normally operated in the latched position to reduce unexpected jarring while drilling and eliminate movement between jar components, increasing service life.
• The EHMJ operates with a simple up and down motion and is not affected by torque.
• The spline drive and latch mechanism are enclosed in a single, sealed oil chamber without ports to the annulus. Such ports on other jars may fill with cuttings and restrict the down jar stroke.
• The EHMJ incorporates a latch mechanism to keep the jar locked in the neutral position and eliminate unexpected jarring while tripping or racking on the derrick.
• The hydraulic delay mechanism is located in a separate chamber to prevent contamination and increase reliability.
• With the latch mechanism in the latched position, the inner mandrel and outer housing act integrally, virtually eliminating seal and inner tool wear during normal drilling conditions. There is no need to extend or open the jar before running in the hole.
• Standard seals in the tool are effective to 250°F (120°C). The jar can be dressed with seals effective to 400°F (200°C) and above for hot hole environments. External sealing surfaces are tungsten carbide-coated to enhance wear and corrosion resistance.
• The EHMJ can be run in tension or in compression within the preset latch setting.

Hydraulic Fishing/Drilling Jar

The Wenzel Downhole Tools Hydraulic Jar (HJ) is a single acting jar designed primarily for fishing applications, jarring in the upward direction. Hydraulically operated, with impact force controlled by the operator, the HJ is ideally suited for fishing, coring, milling or other downhole applications.

Features and Benefits

• The HJ is hydraulically controlled and jars in the up direction, with impact force controlled by the operator.
• 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. These splines are sealed and lubricated to minimize friction and provide long wear life.
• While this jar is designed to be rugged enough for drilling applications, it is intended for fishing, coring, and milling applications.
• A 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 in the tool are effective to 250°F (120°C). The jar can be dressed with seals effective to 400°F (200°C) and above for hot hole environments. External sealing surfaces are tungsten carbide-coated to enhance wear and corrosion resistance.

Operation

Jarring Up

• The Hydraulic Jar (HJ) should be run in the hole in the open position.
• HJ is activated by applying upward pull from the closed position.
• The amount of upward impact force can be changed by varying the amount of overpull applied at surface. See the table for the maximum pull during delay.
• When upward overpull has been applied, the jar will fire after a timed delay. The delay is reduced as upward force is increased.
• After the jar strikes an upward blow, re-setting is quickly accomplished by lowering the drillstring until the jar is in the closed position.

Hydraulic Jar Accelerator

The Wenzel Downhole Tools Hydraulic Jar Accelerator is a hydraulic spring that stores energy when tension is applied to the drilling string. During the jarring stroke, the energy is released upwards to accelerate the drill collars and the upper portion of the Jar, intensifying the jarring impact.

Features and Benefits
