Scribe-ridged diamond element
The Axe SR scribe-ridged diamond element is used with PDC matrix and steel-bodied bits to drill unconventional well intervals, including the vertical, curve, and lateral. 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 strengths (UCS) greater than 5,000 psi [35 MPa].
The Axe SR element extends bit life for longer intervals and sustains the performance of the classic Axe element. The ridged shape reduces the cutting force required by AxeBlade ridged diamond element bits, which lessens overall torque, reduces reactive torque fluctuation, and enables better toolface control in curve applications. This advantage yields better build rates and higher overall ROPs, helping maximize production zone exposure and minimize drilling time.
The Axe SR element complements the benefits of the ridged shape with a scribe shape. Like the Axe element, Axe SR elements combine the shearing action of a conventional PDC cutter with the crushing action of a tungsten carbide insert (TCI), achieving at least 22% deeper penetration to provide higher instantaneous ROP. But when the Axe SR element is strategically placed in the cone of the bit, it uses less WOB and rpm than bits using conventional PDC cutters.
