DOWNHOLE tool provider Peak Well Systems has launched the Peak Hydraulic Jar premium utility toolstring, which it says is simple and easy to redress in the field.

The jar features an inverted upstroke for high angle, standard wireline or wireline fishing operations when installed as part of a standard or fishing toolstring.

Compared to alternative jars available, the unique design of the Peak Hydraulic Jar ensures minimal debris influx during upstroke so that high performance is achieved, even in high debris environments.

The internal workings of the Peak Hydraulic Jar are located in the upper section of the assembly.

Any debris which has entered the outer housing simply falls to the bottom of the tube and away from the critical working components.

It provides variable and sustained jar forces when deployed with a Peak Accelerator, and achieves optimal performance even in high angle, deviated wells if aligned with Peak’s fluted roller centraliser sub, WellGlide.

The simplicity of the Peak Hydraulic Jar, with minimal working parts, means that it is simple and easy to redress in the field.
