By isolating axial bit vibrations from the drill string, the shock tool will reduce lateral and torsional drill string vibrations, and related fatigue damage or failure of the rotary connections.

The Challenger shock spring rate can be adjusted for additional applications such as, P.D.C. bits and used with vibration tools and MWD. The Challenger PDC Shock Tool This design of our Shock Tool is built with PDC bits in mind. The PDC style bit requires far less weight while drilling, the Challenger PDC style Shock is built to operate and perform better with these lower WOB. The typical shock is used and designed to operate with Roller Cone style bits that require significantly higher WOB than a PDC, we designed a shock to run with a PDC application which allows the shock to operate better at the lower WOB utilizing its entire stroke more effectively. When ordering shocks WOB and application information should be considered to assure maximum performance from the Shock Tool.

By isolating axial bit vibrations from the drill string, the shock tool will reduce lateral and torsionaldrill string vibrations, and related fatigue damage or failure of the rotary connections.

    The shock tool allows optimum bit speed to be used under rough drilling conditions, increasing the rate ofpenetration. The Challenger shock spring rate can be adjusted for additional applications such as, P.D.C. bits andused with vibration tools and MWD.

    The Challenger PDC Shock Tool

    This design of our Shock Tool is built with PDC bits in mind. The PDC style bit requires far less weight while drilling,the Challenger PDC style Shock is built to operate and perform better with these lower WOB.

    The typical shock is used and designed to operate with Roller Cone style bits that require significantly higher WOBthan a PDC, we designed a shock to run with a PDC application which allows the shock to operate better at the lowerWOB utilizing its entire stroke more effectively.

    When ordering shocks WOB and application information should be considered to assure maximum performancefrom the Shock Tool.

    Reduces drill string vibration and impact from MWD

    systems

    Adjustable spring rate for P.D.C. applications

    Can be provided in both near bit and string

    applications

    Does not use temperature-sensitive elastomers for

    shock absorption, therefore is suitable for use in

    temperatures to 275F (135C), with optional seals

    available for temperatures up to 450F (230C)

    Reliable Belleville disc springs provide optimum

    load/deflection characteristics to maintain consistent

    contact between bit and formation, effectively

    reducing impact loading to extend bit life

    Low friction torsional drive permits free vertical

    movement

    Reduces wear and tear on rig and equipment, and

    fatigue failures on drill collars and drill pipe

    Automatically compensates for pump open force

    Isolates bit induced vibrations from the drill string

    Pressure balanced to eliminate the effect of downhole

    hydrostatic pressure

    If ran with MWD tool, position shock as close to MWD

    equipment as possible

    With a packed bottom hole assembly, the shock tool

    may be located a minimum of two drill collar lengths

    above the top stabilizer, however bit protection will

    be reduced due to the greater un- sprung mass below

    the tool.

    For maximum effectiveness, the shock tool should be

    positioned immediately above the bit.

    Automatic compensation of pump open effect makes

    the shock tool effective with any combination of bit

    weight or circulating pressure.
