21® Double Duty Drill Collar & Tool Joint Compound
Environmentally-friendly, double duty drill collar and tool joint compound, formulated to provide a superior level of performance for the increasing demands of today’s oilfield market. 21's lead-free formulation contains copper flake as the only metallic component and is fortified by a unique blend of natural, inorganic, extreme-pressure, and anti-wear additives. 21 utilizes our EXTREME base grease which is resistant to invert or high-pH muds and provides better pipe storage properties.
APPLICATIONS:
21 is recommended for the entire drill string in most drilling conditions. Typical applications would include geothermal wells, high angle holes, and problem holes involving high temperature, whip stocks, and horizontal drilling applications. JET-LUBE 21 prevents high stress in drill pipe connections which shortens their useful life.
