integral spiral blade string drilling stabilizer

The Integral Blade Stabilizer (IBS) is a one-piece rotating stabilizer that can be placed near the bit or up in the drill string. It is a one-piece construction manufactured from high-strength alloy steel (non-magnet steel optional). It prevents differential sticking of the drill string by stabilizing the BHA and keeping drill collars and drill pipes away from the borehole wall. This reduces vibration, drill pipe whirl, and wellbore tortuosity; furthermore, the stabilization maintains drilling trajectory whether drilling straight, horizontal, or directional wells.
