Tapered Mill

The Tapered Mill is designed for milling through various types of downhole obstructions, and reaming out liners and whipstock windows. It works well in collapsed casing as well as tight spots. - Removing Downhole Obstructions: Used to mill and grind irregular obstacles in the wellbore, such as: - Broken casing segments, collapsed formation debris, or cement protrusions. - Stubborn remnants of stuck tools, packers, or bridge plugs. - Wellbore Reconditioning: When preparing a well for re-completion, re-entry, or sidetracking by restoring a smooth, uniform borehole profile. - Handling Non-Metallic Debris: Efficiently milling soft to moderately hard materials like plastic, rubber, or composite tool parts.

Product highlights:

➤ Obstruction Elimination: Milling expert for collapsed casing, tight spots, and cemented junk.  

➤ Dual-Function Design: Simultaneously mills obstructions and reams liner/whipstock windows.  

➤ Collapsed Casing Specialist:Tapered geometry navigates restrictions impossible for standard mills.  

➤ Downhole Versatility: Processes everything from scale to stuck oil tools in one run.  

➤ Heavy-Duty Endurance:Tungsten carbide inserts (TCI) rated for 10,000+ psi wellbore conditions.  


Overview of Tapered Mill:

The Tapered Mill is a mission-critical milling tool engineered to tackle the most challenging downhole environments. Its signature conical profile excels where conventional tools fail:  

- Milling through obstructions: Cement, scale, or stuck drilling tools  

- Reaming applications: Opening liner tops & whipstock windows  

- Navigating tight spots: Collapsed casing and restricted wellbores  

"The Tapered Mill works well in collapsed casing as well as tight spots" – leveraging its gradual diameter increase to center itself while generating maximum cutting force. Field-proven to reduce milling time by 25% vs. straight-body designs.

Advantages of Tapered Mill:

✅Unmatched Downhole Access**  

   - Restriction Navigator: 7°–12° taper clears tight spots without hanging up.  

   - Single-Run Efficiency: Combines milling and reaming functions to save trips.  

✅Enhanced Tool Protection**  

   - Vibration Control:Tapered profile stabilizes drilling tools during high-RPM operations.  

   - Debris Management: Integrated fluid ports prevent chip accumulation around downhole tools.  

✅Operational Versatility**  

   - Multi-Material Capability: Mills metal, composite, and cement obstructions.  

   - Pressure-Adaptive Design: Functions in sour gas and HP/HT wells (175°C/350°F).  

✅Cost-Saving Performance 

   - TCI Longevity: Tungsten carbide inserts last 3x longer than milled teeth.  

   - Reduced NPT: Clears obstructions 30% faster than conventional milling tools.
