What Does Copper Cote Mean?
Copper cote is a lubricating grease used to seal and lubricate the joints and collars of a drill string. The compound's anti-seize and low-friction properties come from micro-sized copper flakes and graphite together with corrosion inhibitors and other additives. Copper cote is specifically formulated to withstand wash out and to handle the high temperature and high friction environments of drilling operations.
Trenchlesspedia Explains Copper Cote
The drilling equipment used to drill an oil or gas well is exposed to hostile and corrosive conditions. Drilling mud is pumped through the drill string to clear the well of debris as well as cool and lubricate the drill bit. The equipment constantly runs at high temperatures and high friction levels in order to drill through the rock. Copper cote lubricating grease is designed to prevent seizure and minimize damage to the drill pipes and collars, thus prolonging the life of the drilling equipment.
