Drilling Stabilizers
Control hole deviation. Reduce differential sticking. Ream out doglegs and key seats
Types of Stabilizers we supply
INTEGRAL BLADE STABILIZERSOur Integral Blade Stabilizer sets the standard in both directional and straight hole drilling applications. The all-in-one construction makes it an industry workhorse – able to perform in the most rugged and abrasive drilling conditions. Milled directly into a steel forging, the one-piece rotating stabilizer can be run near the bit or up in the drill string in soft to medium and abrasive formations. |
| Non-Magnetic, Near Bit, String Stabilizer |
REPLACEABLE SLEEVE STABILIZERSOur sleeve stabilizers are the product of simple design coupled with engineered technology. We understand the need to swiftly change out a sleeve on the rig floor which is why our sleeve and mandrel design is virtually foolproof. Our one-piece mandrel is manufactured from high strength 4145 heat treated alloy with ample tong space for connection recuts. |

Connection Features
API connections
All API connections (regular, NC, H90, and PAC) comply with dimensional requirements specified in API Spec. 7-2 and guidelines presented in API RP7G. Other connections are available to meet specific needs.
Phosphate coating
All connections are phosphate-coated to improve resistance to galling.
Stress relief features
API pin stress relief groove and API box boreback decrease the frequency of fatigue failures. These features increase connection flexibility and reduce high-stress concentrations that normally occur adjacent to the end of engaged threads. Stress-relief features are machined in compliance with API Spec. 7-2.
Hard Banding Options
HF5000, HF6000 and HF 6500
