Products by G-FORCE JARS, LLC

G-Force Hydraulic jars use a piston (metering device) and oil to create a time delay. Once the energy is stored, the jar piston bypasses (step), creating a hammer-and-anvil effect that imparts an impact load to the end of the tool assembly. As the jar is pulled in tension, a piston moves through a...

The G-Force Impactor is a double acting accelerator used to increase the impact effect of the G-force Hydraulic jars. The Impactor stores concentrated energy in an optimal position in the Jar string. It helps to absorb impact shock waves that travel up the drill pipe allowing the drill string to be...

The hydraulic jar utilizes an oil reservoir with some type of metering orifice and a bypass area. When the string becomes stuck, overpull is applied. As the force is applied the sliding mandrel will begin to compress the oil in the reservoir, forcing the oil to bleed off slowly through the metering...
