The Ultimate Double Acting Hydraulic Drilling Jar (UHJDA) is a bi-directional drilling jar incorporating hydraulic delay without a latch mechanism, enabling the operator to apply variable impact in both the up and down directions. 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.
• Increased allowable overpull force.
• Hydraulically controlled and jars in both directions.
• Impact force is controlled by a metering device that ensures consistent delay times over the full range of operating temperatures.
• Operates via an up and down motion and is unaffected by right- or left-hand torque.
• External sealing surfaces are tungsten carbide-coated to enhance wear and corrosion resistance.
• Standard and high temperature seals available
• Max pull during delay
