API Spiral Drilling Stabilizer
API Spiral Drilling Stabilizer is a one piece rotating stabilizer which can be
near 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 and keeping drill collars and drill pipes away from the borehole wall. This reduces vibration, drill pipe whirl, and well hole twist. Furthemore, the stabilization maintains drilling trajectory whether drilling straight, horizontal or directional wells.
