Stabilizer

1. INTERGRAL BLADE STABILZERS (IBS)

is a one piece rotating stabilizer which can be placed 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 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 OPTIONAL STABILIZERS

Materials: both alloy steel and non-magnet materials:

(a). Spiral Integral Blade Stabilizer;

(b). Straight Integral Blade Stabilizer;

(c). Non-Magnet Integral Blade Stabilizer;

2. REPLACEABLE SLEEVE STABILIZER

GEPEC replaceable sleeve stabilizer consists of an integral mandrel and a sleeve. One mandrel series can be equipped with different size of sleeve for several hole sizes. The sleeves are easily changed on the rig floor, either when changing hole size or changing the type of wear surface to match drilling conditions

3. NON-ROTATING STABILIZER (RUBBER SLEEVE STABILIZER)

It is a special tool in drilling to avoid blade wear and wall damage. The non-rotating stabilizer consists of mandrel, copper washer, rubber sleeve, spacer sleeve and self-locking lower sub. During drilling, the non-rotating stabilizer transfer the torque by means of mandrel, the rubber sleeve is sliding and moving relative to the mandrel, the rubber sleeve thus plays a role in stabilizer of well. A locking clutch (self-locking lower sub) will avoid sleeve rotation during wash over operation
