A Superior Energy Services Company
Even in normal drilling conditions, the drill string can take a beating. At Stabil Drill, our shock subs are engineered to absorb downhole impacts and vibrations—drastically reducing their transmission to the rest of the drill string. The result is better protection and faster rate of penetration.
From shock subs that absorb destructive vibration to the Hydra Hammer™ jar that delivers precise mechanical force, Stabil Drill equips your string with the tools to take on high-stress environments. Built tough and tailored to your formation, these tools extend equipment life, preserve directional control, and provide the muscle needed when things get stuck downhole.

Vibration is the enemy of your drill string. These heavy-duty subs prevent damage to critical drill string components such as drill collars, pipe and more—even helping protect surface equipment. And Stabil Drill can make and specify them to run in any formation type or temp.
When your drill string is stuck, you need a high-impact fix. The Hydra Hammer Drilling Jar is used to apply a mechanical impact on another downhole component—such as dislodging a stuck BHA. This hydraulic drilling jar is capable of jarring both upward and downward, and can be configured to deliver an impact load in a variety of directions and magnitudes to get you back on track.
