Axe SR
Scribe-ridged diamond element
Overview
Enhanced cutting efficiency for faster drilling
The latest member of the Axe™ ridged diamond element family, the Axe SR™ scribe-ridged diamond element makes drill bits last long and increases ROP performance..
The Axe SR element adds a scribe shape to the ridged design. It combines the cutting action of a regular PDC cutter with the crushing action of a tungsten carbide insert, resulting in at least 22% deeper penetration and higher drilling speed. When placed in the cone of the bit, it requires less WOB and rotation speed than traditional PDC cutters.
Our ridged diamond elements are compatible with any BHA configuration. Bits using the Axe ridged diamond element family improve ROP in medium to hard formations with unconfined compressive strength (UCS) greater than 5,000&nbsh3p;psi [35 MPa].
Applications
Unconventional well intervals, including the vertical, curved, and lateral
Benefits
- Improves cutting efficiency by maintaining a consistently sharp edge
- Maintains sharpness over time through self-resharpening
- Extends bit life due to its self-resharpening properties
Features
Faster and more efficient rock cutting operations that enhance the drilling ROP.
Consistent cutting performance and reduced downtime as the cutting edges continuously wear to expose new, sharp cutting surfaces.
Longer lifespan for the drill bit as the Axe SR element experiences less overall wear and tear as compared with conventional cutting elements.
