A Superior Energy Services Company
Precision-machined for strength and reliability, our drill collars deliver consistent weight-on-bit and performance under pressure.
Stabil Drill’s full range of drill collars—from compact pony styles to high-spec non-mag options—brings reliability to every formation. Optimized designs reduce drag, improve toolface stability, and mitigate sticking risk, while our coatings and treatments prevent corrosion and extend collar service life.

Also known as a Short Drill Collar (SDC), pony collars measure less than the standard drill collar length. While our average drill collar length is 31’ 6”, pony collars can measure between just five and 15 feet.
Thicker portions of the pipe wall are known as upsets. Used in high-stress applications, these collars feature center upsets which reduce hole drag—improving overall rate of penetration and maintaining drill string steer-ability.
These drill collars are designed with a smooth surface that comes just as they were mill rolled. These designs are preferable when you need more weight and contact with the wellbore wall.
These collars are machined with spiral grooves throughout their length to help minimize wall contact, which dramatically reduces the risk of sticking during operations.
Our non-magnetic drilling collars are typically made slick, but can be spiral-machined as needed. These collars are often used in directional drilling applications to avoid interference.
For enhanced resistance to corrosion on non-magnetic collars, Stabil Drill applies a mechanical bore treatment (RSC or roller burnishing) and shot peening on outside diameters. Stabil Drill's exclusive MAGCOAT process can also be applied to extend tool life and reduce galling by up to ninety-nine percent.
