Where it is used

Axe TR triple-ridged diamond elements are used with matrix- and steel-bodied bits to drill unconventional well intervals, including the vertical, curve, and lateral. Ridged diamond elements are compatible with any BHA configuration. And bits using the Axe TR element improve ROP in hard formations with unconfined compressive strength (UCS) greater than 5,000 psi [35 MPa].

How it improves wells

The Axe TR triple-ridged diamond element extends bit life for drilling longer intervals because the triple-ridged shape not only better absorbs impact loading to reduce the effects of impact damage but also reduces cutting force. This 3D cutting element lessens overall torque, reduces reactive torque fluctuation, and improves toolface control in curve applications. These advantages yield better build rates and higher overall ROPs, helping maximize production zone exposure and minimize drilling time.

How it works

Like the original Axe ridged diamond element, the Axe TR element combines the shearing action of a conventional PDC cutter with the crushing action of a tungsten carbide insert (TCI). This combination achieves at least 22% deeper penetration to deliver higher instantaneous ROP while using less WOB and reducing the rpm from that applied to conventional PDC cutters. The Axe TR element was developed specifically to endure high-impact drilling conditions without sacrificing cutting efficiency. The triple-ridged shape increases impact strength by 15% while improving cutting efficiency by 29% in carbonate formations and by 4% in sandstone formations.
