The Jar incorporates harmonised hydraulic and mechanical functions improving reliability and performance in both oil and gas wells. By maintaining an overpull, the Jar will trip and ‘fire’ the toolstring upwards in a rapid motion. The jar is then simply re-cocked by setting down toolstring weight to re-latch the body to the jar rod. Unlike most jars available on the market the jar collet latch mechanism is positioned in the upper section of the jar housing. This makes the jar less prone to failure by the incursion of debris in and around the latch mechanism during utilisation.
