JLS® Tool Joint Compound is a high quality product contain- ing premium grade copper flake, amorphous graphite, rust and corrosion inhibitors, and other inorganic solids. All are blended in JET-LUBE’s unique grease compounded from custom refined, low-sulfur oil to ensure brushability over a wide temperature range, tenacious adherence to all surfaces, re- sistance to water washout, and prevention of rust/corrosion.
JLS is a result of laboratory and field development efforts spanning several decades. It is manufactured under the industry’s toughest quality control regimen and is especially designed to prevent thread and shoulder wear, and to provide superior performance on the rig floor and downhole in me- dium duty drilling just as KOPR-KOTE® and JET-LUBE 21® perform in more severe conditions. For invert muds or high-pH muds, a special base grease is available.
- Lead Free
- Zinc Free
- Formulated with a proprietary blend of copper flake, graphite, and other inorganic additives for protection and prevention of excessive circumferential make-up of tool joints in average drilling conditions.
- Unique high temperature grease base with brushability over a wide temperature range.
- Sticks to wet joints.
- Low sulphur content.
- Consistent rig floor make-up.
- Resistance to further make-up downhole in medium drilling.
- Available in Arctic and Thermal base greases.
JLS is recommended for use on tool joints in a variety of drill- ing depths and formations. It provides consistent control of make-up and break-out in these conditions and protects against galling and seizure. JLS prevents excessive stresses which shorten tool joint life, and the metallic solids of JLS form a gasket on threads and shoulders that prevent metal-to-metal contact under high torque loads.
