Four versions are available:

• GunDRILL 6 Blade Bi Directional Reamer
• GunDRILL 4 Blade Bi-Directional Reamer
• GunDRILL 4 Blade Directional Reamer
• GunDRILL 6 Blade Uni-Directional Reamer

The GunDRILL Reamer is a versatile drilling reamer. This unique PDC-based reamer is the only one of its type on the market today, delivering accurately gauged and high quality wellbores. This tool can open boreholes in cases of severe swelling and/or borehole instability.

It provides reaming through a simple blade design that uses proprietary Tungsten Carbide Inserts (TCI) that provide more reaming or stabilization according to the drilling and formation conditions and maintains the gauge for extended durations. TCI distribution is optimized to provide continuous reaming in longitudinal and radial directions. The Rubicon PDC distribution works with our in-house cutter matrix design, resulting in balanced drilling and reduced vibrations. PDC gauge is passive allowing it to interact with formation only when undergauge occurs.

The GunDRILL Reamer is highly flexible being uni- directional for applications where only back reaming is required and bi-directional for applications where front and back reaming is required. There is also the directional variant with flat TCIs for application where sliding is expected. The tool can be made in steel and non- magnetic configurations to extend the flexibility of tool placement anywhere along the BHA.

By utilizing the GunDRILL Reamer the borehole is reamed to perfection, the BHA can be pulled to surface safely overcoming high torque, multiple sticking points and difficult intervals. In some situations, it increases ROP due to smoother running in hole and casing /completions can be set to TD without issue.
