• Bowen ™ Ultra Hydraulic Coiled Tubing Jar


    The Bowen™ Ultra coiled tubing jar is a bi-directional hydraulic CT jarring assembly designed to operate in conjunction with the coiled tubing jar intensifier. This jar’s unique design allows for easy, dependable, and hard hitting operation, with no setting or adjustment is required before going in the hole or during operation. The assembly allows the operator to easily control the intensity of jarring impacts by varying the applied load. The jar can deliver a wide range of impacts, from low to very high impact and impulse forces. The new patent-pending technology within the assembly allows the tool to deliver higher impacts.

    To complement the new Ultra CT jar, we have designed a new jar placement program that provides impacts at the stuck point for service companies and operators to use.

    The new CT jar placement program:

    • Impacts at the stuck point, not just the jar

    • Allows the service company to optimize the BHA to deliver the hardest impact and impulse

    • Considers configuration and length of fish, hole profile, friction, mud weight effects, CT size, etc.

    • Program designed only for NOV tools - all calculations and results are based on NOV tools

    • Customers can download program for free at nov.com

    NOV offers free technical support on the program and our tools 24/7 at 1-888-DHT-TOOL.

    We will run jar impact calculations for customers through the 24-hour hotline.
