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 Tercel 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 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 applications 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.
Uni-directional GunDRILL Reamer
The single direction (uni-directional) GunDRILL Reamer is suitable for applications where only back reaming is required.
Bi-directional GunDRILL Reamer
The bi-directional GunDRILL Reamer is suitable for applications where front and back reaming is likely.
Directional GunDRILL Reamer
This directional variant is suitable for applications where drilling directional holes with mud motors and sliding is required.
