Cougar Drilling Solutions



At Cougar, we work in close collaboration with each of our clients to understand your needs and provide stabilizers that are consistently constructed to exacting standards. To start with, we use only 4145H heat-treated, stress-relieved steel — every bar of which is tested by independent metallurgical laboratories to verify its quality. We then dedicate a single piece of steel for each stabilizer that we mill. All connections are machined to API specification, with bore back, stress-relief and phosphated.

Benefits & Features

Plasma Transfer Arc

Cougar consistently uses Plasma Transfer Arc (PTA) to rebuild Cougar stabilizers to the correct gauge. PTA consists of a nickel-based hardfacing powder containing tungsten carbide. This alloy is specifically designed to stand up against severe abrasion or moderate combined corrosion and abrasion. PTA is abrasion and friction resistant because of tungsten carbide particles that are evenly distributed throughout the entire matrix of the stabilizer blade. This production of tiny grains of tungsten carbide, melted by a revolutionary process, reaches a hardness of 3000-4000 on the Vickers hardness scale.

Cougar uses unique welding methods, applying tungsten carbide directly to the base metal of the stabilizer instead of laying it on the carbide.
