KOPR-KOTE

KOPR-KOTE® drill collar and tool joint compound is a premium-quality, unleaded compound containing copper flake, graphite, and other natural extreme pressure and anti- wear additives. KOPR-KOTE’s solids package is formulated to prevent excessive circumferential makeup by increasing the coefficient of friction under compressive forces. As stress levels rise above 50% of yield, the friction factor increases, limiting downhole makeup. Full hydraulic joint efficiency is maintained allowing joint shoulder faces to mate completely without standoff or deformation. For invert or high-pH muds, use Jet-Lube®    EXTREMETM. For wedge-type thread connections, use NCS-30® ECFTM for best thread-wear protection.

For optimum performance on API drill string connections,KOPR-KOTE should be utilized with the torque charts in API RP7G or by contacting the drill pipe and connection manufacturer.Premium drill string connections such as HI-TORQUE® (HT), eXtreme® Torque (XT®), and XT-MTM connections, etc., utilize make-up torques based upon thread compound friction factors of 1.0. Therefore, use the torque provided by the premium connection manufacturer. Adjusting make-up torque based on thread compound friction factor may still be advised.

PRODUCT CHARACTERISTICS

* Many factors such as pipe size, thread geometry, drilling mud contamination, etc. affect the friction factor. This is a relative number and in all applications experience and prior knowledge should be used to adjust make-up torque accordingly. Contact your drill pipe manufacturer for torque and friction-related specifications.
