Integral Blade Stabilizer Fishing neck length 660-772 mn Crown length 254-508 mm
Descriptions of Integral Blade Stabilizer Fishing neck length 660-772 mn Crown length 254-508 mm:
Integral Blade Stabilizer (IBS) is a one piece rotating stabilizer which can be placed near bit or higher in the drill string. It is a one piece construction manufactured from high strength alloy steel (non-magnet steel optional), that prevents differential sticking of the drillstring 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.
