Jar Impact Amplifier

The Gotco Jar Impact Amplifier is a vital accessory tool designed to be run with the Gotco Hydraulic Fishing Jar. It will accelerate the upward motion of the drill collars and the fishing jar allowing the operator to apply significantly greater impact to the fish.

This particular helpful in deviated holes where friction may reduce the impact of the jar or in shallow holes where ther is insufficient string length to provide adequate stretch to the running string. Acting also as a shock absorber to the rebounding string, the jar impact amplifier will protect tools and string from damage.

Construction

Manufactured from high strength alloy and heat treated for maximum toughness, the jar impact amplifier is both rugged and reliable. Heavy splines allow the application of full torque and a generous through bore offers unrestricted circulation at all times.

Operation

The jar impact amplifier should be located in the string immediately above the drill collars. No presetting is required. When a stretch is applied to the string, the jar impact amplifier fluids are compressed, storing additional energy. When the jar trips, this energy is released. The tool will automatically reset, each time the jar trips, and will continue to operate as many times as necessary to free the fish.

Service Kit

A service kit is required to properly redress and fill the hydraulic jar. One kit will service all Gotco Jars and Jar Impact Amplifiers.

Setting Tools

A mandrel body setting tool is required for each size of jar impact amplifier. Setting tools are used to properly position and set the standard copper back-up and non-extrusion rings.
