Impact Selector :: Wireline Jar DemonstrationWith over 1,000 descents behind it, the Open-Hole MCT is the world's first multi-conductor, all-mechanical open-hole jarring tool. Uses patented technology to reduce the risk of costly "stripover" downtime and the need for expensive pipe conveyance or logging-while-drilling. Helps overcome tool-string differential sticking and increases the string's ability to function in deviated holes. Provides a stroke length of 9-3/4 inches. This proven tool has been endurance-tested at 30,000 psi and 500 degrees F.
